Wireless Ad Hoc Network Of Organizations In A Leap-forward Routing Protocol Design And Implementation,

The routing protocol is a key technology in wireless self-organized networks. In a self-organized network, the topology structure changes quickly and the wireless channels have a very limit bandwidth, sometimes there are one-way communication channels in the entire network. These characteristics need the routing protocol to be quickly converged, avoid routing ring and infinite counting, be able to treat one-way channels and have a low costs.This dissertation was based on the project"The half real simulation system of wireless self-organized networks", its target was to design and implement an efficient routing protocol used in a self-organized network. By studying the zone method of ZRP and improving the link-layer four hops routing protocol which was already used in this project, this dissertation designed a new routing protocol which used a logic next-hop. Be different form traditional routing protocols, the next-hop in each routing entry selected by this protocol would be a logic neighbor host. The network layer could take all in-zone hosts as neighbor hosts. This mechanism would decrease the influence of topology's changes in local areas. When designing this protocol, the cross-layer principle and the mechanism"routing in network layer and relay in link layer"were used. The reason why taking advantage of the link layer was that the link layer could aware the neighbor hosts and local topology structure faster than the network layer, it could also enhance the flexibility of routing protocol.This routing protocol was designed and implemented in the linux operation system, debugged and tested in the half real simulation system. The principle of logic next-hop can be referenced by other routing protocols used in the plane structured self-organized networks.
