AI Technical Summary

Problems solved by technology

This process requires many message exchanges, resulting in multiple channel collisions
[0005] Thus, while standard SIP operates satisfactorily in a single-hop environment, standard SIP tends to fail in a multi-hop environment because the broadcast of SIP registration messages exponentially increases the chance of collisions in the MANET channel

Embodiment Construction

[0020] Example embodiments of the present invention provide a resource and location management solution that is independent of the underlying MANET routing protocol. This example embodiment uses enhanced SIP that can be used in a dynamic, multi-hop MANET. The example embodiments provide a fully distributed fault-tolerant communication system and method that uses fewer messages, generates fewer channel collisions, and facilitates fast updates to account for the dynamic nature of MANETs.

[0021] In an example embodiment, a MANET may include multiple network devices (eg, wireless telephones, wireless equipped PDAs, wireless equipped computers, etc.), each device representing a node within the network. Each node can be assigned a unique ID within the MANET, which can be derived from a MAC address, social security number of a user associated with that node, CPU id, or any other identifier that is unique to that node. Alternatively, a form of authentication can be used to ensure t...

Abstract

The invention is a method for registering first equipment (node 1) in AMNET, in an instance, transmitting register information to single-hop adjacent equipment (S10), where the register information includes hop limit and freshness indicator of first equipment and the freshness indicator indicates the experience grade of the first equipment in the MANET and the hop limit indicates the limit to number of hops of transmitting register information; in another instance, receiving register information (S50) of first equipment, where the register information includes first freshness indicator and the first freshness indicator indicates the freshness of the register information; based on the received register information, able to transmit its reverse register information (S75) and / or it to other equipment (S80).

Description

Background technique [0001] Mobile Ad Hoc Networks (MANET) are designed to serve as network devices in areas where no base stations, routers, or access points are available, such as battlefields, post-disaster areas, and other areas lacking network capabilities Provide means of communication. MANETs can be used for any purpose generally associated with networking, such as making voice and video calls, sharing photos, audio and video clips, playing games, and generally exchanging information. Some research has been done on using the Session Initiation Protocol (SIP) as a resource and location management mechanism. [0002] SIP is a signaling protocol used in 3G networks for establishing, managing and withdrawing sessions. Generally, SIP uses a client / server architecture where each SIP client registers an IP address and a unique ID with a SIP registrar in a process known as binding. To initiate a communication session, a first client sends a communication request to a SIP red...
