An apparatus includes a network node configured to communicate with other network nodes via a communication network. The network node includes a plurality of transceivers and a controller. The controller includes a packet management module that identifies a link profile solution set that includes a set of link profiles corresponding to communication links for multicasting the message packet. The link profile solution set maximizes coverage of network target nodes of the multicast message packet. The packet management module places a first message clone of the message packet in a transceiver queue for transmission to one or more of the network target nodes, updates the link profile solution set when the first message clone reaches the end of the transceiver queue, and initiates transmission of the first message clone or drop the first message clone according to the updated link profile solution set.

Just in time link transmission for a multi-frequency multi-rate multi-transceiver communication device

A modified protocol independent multicast (M-PIM) routing protocol is an improvement to protocol independent multicast (PIM) routing protocol. M-PIM is optimized for use with at least one low bandwidth multi-hop network. The improvement comprises at least one modification to PIM that facilitates the transport of multicast traffic in a multi-layer routing system.

Protocol for multicasting in a low bandwidth network

A node (-) determines a power level for transmitting to a neighboring node (-) in a wireless network (). The node (-) receives one or more messages indicating a location of the neighboring node and a type of directional antenna of the neighboring node (-) that transmitted the one or more messages. The node (-) determines the power level for transmitting to the neighboring node (-) based on the location of the neighboring node (-) and the type of the directional antenna.

Systems and methods for directional antenna power control in a wireless network

A communications system has stations arranged in clusters (and) of communication member stations (CM, CM, CMand CM), with one member station (CH, CHor CH) in each cluster being a head station for the cluster. Each member station (CM, CM, CMand CM) communicates with the network through a cluster head station (CH, CHor CH). The cluster head stations (CH, CHand CH) communicate among other cluster head stations (CH, CHand CH). A mobile communications station (e.g., CM) evaluates a beacon message received from a first member station (e.g., CM) of the plurality of mobile stations through a transceiver. The station CMalso determines whether to communicate with the first member station CMdirectly or to communicate with the first member station CMby forwarding messages through a cluster head station CHthat is affiliated to the mobile communications station CM

Using direct cluster member to cluster member links to improve performance in mobile communication systems

A system tests the protocols for a network containing a group of network devices. The system includes a simulation controller () that transmits network configuration information during the protocol testing and one or more nodes (-to-N) that emulate a network device, receive the network configuration information from the simulation controller (), and perform one or more operations in response thereto. The system also includes an analysis device () that monitors and analyzes the nodes (-to-N) during the protocol testing.

System and method for testing protocols for ad hoc networks

A system selects an antenna for transmitting data from a node ( - ) in an ad-hoc, multi-hop, wireless network ( ). The system receives a message from another node ( - ) of the wireless network ( ), the message including location data associated with the other node ( - ). The system determines an angle from the node ( - ) to the other node ( - ), based on the location data, to produce a determined angle. The system selects an antenna from a plurality of antennas for transmitting data to the other node ( - ) based on the determined angle.

A network for routing packets includes multiple nodes. A first node has a direct link to a second node. The first node receives a packet and identifies a primary next hop to which to transmit the packet ( ). The primary next hop identifies at least the second node. The first node transmits the packet to the second node ( ), determines whether the transmission was successful ( ), and identifies at least a third node when the transmission to the second node was unsuccessful. The first node identifies the third node by: finding a node in the network that has a direct link to both the first and second nodes ( ); identifying at least one alternate next hop, assuming that the link between the first and second nodes is unavailable, determining the cost associated with each of the alternate next hops, and selecting one of the alternate next hops based on the determined cost ( ); or retrieving a predetermined alternate next hop from a forwarding table stored by the first node ( ). The first node then transmits the packet to the third node for forwarding to the second node ( ).

A communications system for communication among plural stations in a network has stations (CH CM CM CH CH CM CM ) arranged in clusters ( ) of communication member stations, each communicating with each other. One of the member stations (CH CH CH ) is a head station of the cluster. The cluster head stations (CH CH CH ) communicate with other cluster head stations (CH CH CH ). A method for configuring the network of stations includes a step of operating at least a first (CH ) and a second (CH ) station of the plural stations as cluster head stations, the first (CH ) and second (CH ) stations forming a communications link. The method also includes a step to resign the first (CH ) station from operating as a cluster head station when a predetermined resignation condition is met. The method also includes a step of maintaining the communication link between the first (CH ) and second (CH ) station as the first station (CH ) transitions from operating as a cluster head station (CH ) to operating as a cluster member station (CM ) of a cluster headed by the second cluster head station (CH ).

A communications system for communication among plural stations in a network has stations (CH , CM , CM , CH , CH , CM , CM ) arranged in clusters ( ) of communication member stations, each communicating with each other. One of the member stations (CH , CH , CH ) is a head station of the cluster. The cluster head stations (CH , CH , CH ) communicate with other cluster head stations (CH , CH , CH ).
