A Zone Routing Protocol Based on Cluster
LI Li-xin · Journal of Southwest University · 2011
Because of the defect of the zone generating algorithm in zone routing protocol(ZRP),a new protocol,C-ZRP,is presented in this paper.By changing the zone generating algorithm,the nodes no longer enter the overlap zone repeatedly,thus reducing the number of routing tables in the nodes and the broadcast packets generated by route lookup and lowering the routing overhead.In addition,the geographical information is introduced to trigger the route updating,which lowers the network overhead.The result of a simulation test with ZRP and C-ZRP based on NS-2 shows that C-ZRP has a distinct advantage in controlling the routing overhead and the network overhead.
