A wireless mesh network is described. The mesh network uses a plurality of data communications nodes that are organized in a tree-like structure. The network also includes an access server which communicates with the nodes. The mesh network nodes are one or more root access point nodes having a wired connection to an external network; and one or more mesh access point nodes. Both types of nodes communicate with an external network. Each non-root node automatically connects to an associated parent node selected from one or more nodes within a direct wireless communication range of the node. The node selects a parent node based on one or more parent selection criteria from the access server and establishes a connection to the selected parent node. The node then calculates its routing path to the external network. The nodes include unique identifiers and two or more radios.

High performance wireless network

A multilayer architecture for supporting variable networks is discussed. The architecture includes an application layer in communication with a simulation and network management layer and a coupling layer. The coupling layer interfaces with physical connections within a network device and the remaining layers; and wherein the simulation and network management layer sets one or more network parameters within the application layer.

Evolutionary wireless networks

A network combining wireless and wired elements is described, using a multi-slot modular mesh node to house diverse transceiver elements (e.g. IR, Wi-Fi, Powerline). A radio agnostic tree based mesh network is formed, based on what type of wireless links are formed on the uplink and downlink of the backhaul and what type of radios are used for the Access Points AP. In addition to servicing IP based clients (e.g. Wi-Fi, WiMax, Bluetooth), the modular mesh nodes APs may also serve as receivers/collectors for low cost chirp devices. The method of transport is standard IP based packets yet security is inherent in this chirp-based implementation: only mesh nodes are privy to the routing tables that indicate that packet addresses are not IP. Multiple methods to obfuscate packet flow are presented. An organic approach to providing category/class based form of data type identification is proposed, to support a (dynamic) M2M Social Network Applications in-device discovery, registration and control are presented.

Chirp networks

A tree-shaped mesh network is discussed which uses a mesh of wireless nodes that form a tree shaped network with one root node having a connection to an external network; chirp clients; and wireless network clients. Chirp clients comprise low cost chirp devices wherein said low cost chirp devices transmit short duration messages wherein transmission of said short duration messages are scheduled at preset transmission intervals. At least one wireless node of the mesh of wireless nodes is a designated chirp-aware node wherein said chirp-aware node sets the preset transmission intervals for chirp client communication by broadcasting a beacon prior to transmission by chirp clients and said chirp-aware node further comprises a bridge between the short duration messages and IP based devices wherein said bridge includes a wireless receiver to receive the short duration messages and is connected to said external network. The short duration messages are encapsulated into action frames, for onward transmission to other chirp aware routers. Each wireless node further comprises two logical radios and a service radio wherein each wireless node uplink and downlink operates on distinct non-conflicting frequencies. The wireless network clients communicate with the wireless nodes using node service radios.

Terse message networks

In one version, the system uses a mesh of wireless nodes that form a tree shaped network. One of the nodes is a root node that has a connection to an external network, with other network participants being chirp clients, and wireless network clients. The chirp clients are low cost devices that transmit short duration messages that are scheduled using a chirp scheduling technique. At least one wireless node of the tree shaped network is designated as chirp-aware and has a bridge between the short duration messages and IP based devices. The bridge includes a wireless receiver and is connected to the external network. All nodes other than the root node disregard the short duration messages using adaptive filtering. Each node has two logical radios and a service radio, the nodes' uplink and downlink operating on non-conflicting frequencies. Wireless network clients communicate with the nodes using the service radios.

A wire-less/Wired mesh network is described, using a multi-slot modular mesh node to house diverse transceiver elements (e.g. IR, Wi-Fi, Powerline). A radio agnostic tree based mesh network is formed, based on what type of wire-less links are formed on the uplink and downlink of the backhaul and what type of radios etc are used for the Access Points AP, see FIG.. In addition to servicing IP based clients (e.g. Wi-Fi, WiMax, Bluetooth), the modular mesh nodes APs may also serve as receivers/collectors for low cost chirp devices. These devices are not 'agile' and therefore contentious. APs, servicing these devices, alleviate potential contention by multiple means including: sending out a 'incoming' CTS, efficient delivery through container based schedulable bus deliveries, and its reverse (moving chirp transmission times to be sequential). Multiple approaches for &#x201c;pollen&#x201d; to reach the intended &#x201c;flower&#x201d; in a timely manner are described. The method of transport is standard IP based packets yet security is inherent in this pollen-flower based system: only mesh nodes are privy to the routing tables that indicate that packet addresses are not IP. Multiple options to further obfuscate packet flow are presented. A multi-agent based approach driving business process flow is described. Such agents can also provide specialized mesh network routing e.g. navigation agents for chirp devices. Tree based routing and logical radio abstractions are revisited. An organic approach to providing category/class based form of data type identification is proposed, to efficiently match publishers and subscribers, based on the type of data being sought. A private, secure and natively Publish/Subscribe M2M community is engendered at the edge. It has loosely, dynamic and ad hoc couplings to big data servers, also operating on their own private exchange/market place, using a real time publish/subscribe infrastructure with content categories used as part of pollen identification.

The system describes a collaborative machine social network system with several elements. There is at least one system participant which communicates with the network. The participant's communications include short bursts of information not directed to a particular recipient but rather the network as a whole. The network further includes propagator nodes and integrator nodes to process communications from participants.

Collaborative logistics ecosystem: an extensible framework for collaborative logistics

There exists a need to reduce re-transmission delays in real time feeds (such as video) by sending the packet with sufficient repair/recovery information inside the packet container so the relaying stations and/or the receiving devices can fix errors in transmission by perusing the contents of the packet and the repair information, and modify the packet and then relay it. By providing the relaying station the ability to fix the error, retransmission of the packet is avoided along each relay station along the network path from source to destination and also by receiving devices that would otherwise request a re-transmission. This application teaches a method so real time streams (e.g. video) may be more efficiently transported over a CSMA based network.

Real-time packet transforms to avoid re-transmissions

A self-forming VoIP connection capability is described that may be superimposed over wired networks, wireless networks, or combinations thereof. As described herein, a local network cluster forms while isolated from a conventional SIP server, or alternately may exist as a cluster of network nodes and clients that later becomes isolated from a conventional SIP server by a break in the network. Either way, each network node thus enabled with distributed SIP registry functionality according to this invention independently constructs a local SIP registry and SIP server capability within that node. Subsequently, while isolated from a conventional SIP server, VoIP conversations among client devices connected to nodes within an isolated cluster will continue, and nodes and clients may join or leave an isolated cluster with conversations able to be initiated or continued while a node has network connectivity to the cluster.

Self-forming VoIP network

A structured wireless mesh network is disclosed where a tree-like connection topology is formed. In one embodiment, each node has separate uplink and downlink radios operating on different channels. When a cluster of such nodes becomes isolated as in the case of a mobile mesh application, a node in the cluster according to this invention acts as a root node thus enabling the tree structure to persist, even in isolation. Example methods of joining sub networks are disclosed that guide the joining of mesh networks and channel management. Nodes that may operate in isolation also support a distributed DHCP capability such that IP addresses are assigned to clients even when a connection to a central DHCP server is unavailable.

Persistent mesh for isolated mobile and temporal networking

A system of aggregating messages utilizing at least one device transmitting at least one short communication message wherein said short communication message comprises a terse command or status message; at least one network router comprising a means of receiving the short communication messages; wherein said means receives said short communication message without interrupting other communications; and an uplink from the at least one router to an external ip-based network wherein said router aggregates said short communication messages and forwards the aggregated messages via the uplink to the external ip-based network wherein said external ip-based network comprises a tree-based logical network comprising wireless nodes.

Real time packet transforms to avoid re-transmission

A design and proof of concept of a new type of WLAN, complete with simulation and results from the simulation has been described. Each AP Node is implemented as a self-contained embedded OS unit, with all algorithms resident in its Operating system. The normal day-to-day functioning of the AP node is based entirely on resident control algorithms. Upgrades are possible through a simple secure communications interface supported by the OS kernel for each AP node. Benefits provided by a wireless network, as proposed in this invention, are that: it installs out of the box; the network is self-configuring; the network is redundant in that mesh network formalism is supported, ensuring multiple paths; load balancing is supported; there is no single point of failure; allows for decentralized execution; there is a central control; it is network application aware; there is application awareness; there is automatic channel allocation to manage and curtail RF interference, maximize non interference bandwidth and enable seamless roaming between adjoining wireless sub networks (BSS) and it supports the wireless equivalent for switching&#x2014;for seamless roaming requirements.
