Various embodiments that pertain to network functions are described. A network can be an ad hoc network that function with peer-to-peer communications. The network can be physically decentralized, yet logically centralized. Various functions can be practiced within this network environment. In one example, a provider can provide an authorization to a robot by way of a peer-to-peer communication. The robot can validate the authorization and practice what is authorized in response to the authorization being validated. This authorization can be to perform a function autonomously for a defined length of time.

Various embodiments that pertain to artificial intelligence algorithms. A repository can retain a reusable common set of artificial intelligence algorithms. Different users can access this common set of artificial intelligence algorithms and employ individual artificial intelligence algorithms in programs as appropriately as they are developing different applications and/or products. Employment of these individual artificial intelligence algorithms can include, for example, tailoring parameters based on the desires of the individual user's desires using the same common set of algorithms or individually or as a group as appropriate.

A cross-layer security scheme can be used for a Multi-Input Multi-Output (MIMO) antenna-based large-scale multihop mobile ad hoc network (MANET) with a set of frequency-nonselective, slow/Rayleigh fading, and uncoded channels along with interference combining both physical, link, and higher layer encryption techniques for the payload in addition to signaling. Furthermore, MIMO-aware cross-layer secure MANET physical and key-based logical hierarchical routing proving scalability can be used. Security can be provided in Multi-Hop MIMO MANETs in Physical, medium access control (MAC), and internet protocol (IP) Routing layer. The MIMO-aware MANET IP Routing can include two kinds of routing: Physical Routing such as secure ad-hoc on-demand distance vector (SAODV) in the access MANET and Secure Key-based distributed hash table (DHT) 'logical' routing in the backbone MANET. Both security and performance metrics can be employed to improve (e.g., optimize) both network secrecy and throughput/bandwidth capacity.

Various embodiments are described that relate to a generalized Bloom filter design methodology. The Bloom filter design methodology can be used for preventing Bloom filter-specific cyber-attacks instead of designing special-purpose Bloom filters that can be applied preventing a specific kind of attack for a given kind of communications networking environment. The resultant security functionalities that can be considered as a package for the generalized secure Bloom filter can include Identifier Modifications, Secure Indexes, Dynamic Salting, Independent Multiple Hash Functions, Random Bit Insertions, Fake Bit Injections, Secure Record Linkage, Single Bloom Filter with all Identifiers, and Encryption. The overall secure generalized Bloom filter algorithms can be devised along with numerous sub-algorithms for these functionalities for making the Bloom-filter-based communications over a network providing robust security, reliability, and availability, preventing known cyber-attacks.

Various embodiments are described that relate to network communication. In a mobile peer-to-peer ad hoc network, nodes can use a context-aware key-based distribution hash table routing algorithm to create the route scheme. This can be done among nodes that are cluster-heads while nodes that are within a cluster can use a non-context based algorithm.

A framework of a common mobility management protocol for Q.5/16 includes a high level protocol for performing the functions of address resolution, routing, location update and authentication. The common mobility management protocol can be used by existing and future multimedia applications (MA's) to support mobility management for messaging among mobility management authentication function (AuF), home location function (HLF) and visitor location function (VLF) databases/servers, and the corresponding multimedia application functional entities (MAFEs) of the multimedia applications (MA's). The common mobility management protocol may replace, act in concert with or in sequence with existent interworking protocols for the various multimedia applications. Reference point architectures, functional characteristics, features, and capabilities of the protocol are described including call flows and message syntax. The disclosure presents the scope of Q.5/16 and how H.MMS.1 (H.323 Mobility), H.MMS.2 (Global Mobility), and H.MMS.3 (Presence/Instant Messaging Mobility) can be a part of the same common mobility management protocol.

An interworking function (IWF) for a first and second protocol based network, for example, an H.323 protocol based network and an SIP protocol based network comprises an interworking gateway server including a state machine for defining each call processing state and a translation table for use in translating addresses formatted in each protocol. A method of interworking for use in interworking between said first protocol based network and said second protocol based network comprises the steps of receiving at said interworking gateway server serving said first and second protocol based networks a request from an endpoint in the first or second protocol based networks, establishing a state machine in memory whereby, for each state of said state machine, a message associated with that state is categorized as one of a triggering message, a non-triggering message and an error message, establishing a translation table in said memory whereby an address formatted in said first protocol has a one-for-one correspondence with an address formatted in said second protocol, processing said request in accordance with said translation table and said state machine and permitting communication between said first and second endpoints utilizing a realtime transport protocol. In the event media is terminated at said interworking gateway server, the interworking gateway server, in one embodiment, comprises a media switching fabric for switching media terminated at the gateway to an addressed endpoint capable of receiving it.

A customer premises border element is disclosed that functions as an interface between devices, such as SIP devices located on a customer's premises, and a border element located in the service provider's network. Such customer premises border elements are advantageous in that they are relatively inexpensive since they only have to support devices located on the customer's premises. At the same time, by performing a number of functions, such as media transcoding and a portion of call processing, it reduces the processing requirements of network border elements.

An access architecture for real-time communications is described. The architecture includes an inter-architecture network utilizing a single protocol, a plurality of border elements in communication with the inter-architecture network and with an external network, and one or more call control elements in communication with said inter-architecture network. The external network utilizes any of a variety of known networking technologies and protocols. The inter-architecture network utilizes a single protocol such as SIP. The present architecture provides a single common infrastructure for offering real-time communications services independent of call control protocols and networking technologies.

The present invention provides a method and system for assuring H.323 alias address portability to an H.323 user in real-time H.323 multimedia communications where the H.323 user is registered with a home gatekeeper for the home zone of the H.323 user. Alias address portability may be obtained using a central database that is known to the administrative zones and is used for alias address mapping, or alternatively, may be obtained by using a distributed database. The method may be implemented by: sending, by the H.323 user, a message with a called H.323 entity's alias address, to the home gatekeeper to originate a call to the called H.323 entity; confirming that the alias address, services, and service providers are portable; converting the alias address to a called routable alias address for the called H.323 entity and sending the alias address to the H.323 user; and placing the call to the called H.323 entity.
