Research on Communication Protocol Agreement Based on Ad Hoc Network

Routing technology is the key technology of Ad Hoc network and is one of the most important factors influencing overall performance of network. Routing protocol has not adapted to topological structure of dynamic change for Ad Hoc network, so the new Ad Hoc routing protocol must be designed. The paper starts from the basic concept of Ad Hoc network and proposes an effective key protocol agreement in Ad Hoc network based on bilinear pairing and hierarchical routing protocol which not only makes logical key agreement model correspond to topological structure of actual network , but also supports the establishment and dynamic update of initial group of key and has less communication traffic. The performance analysis indicates that the protocol proposed in the paper is very effective on the network with larger range, stronger ability of equipment process and worse communication environment.
