Research on Clustering Routing Protocol of MANET

摘要

In general, each cluster consists of a cluster head and several member nodes in clustering routing protocol of MANET. Its advantages are obvious, such as better scalability, less control overhead, and it also reduce the number of nodes sharing the same channel. But it needs a clustering algorithm to maintain the hierarchy so that it can adapt well to changes of network topology, and the routing elected by the clustering algorithm is not always optimal. This paper proposes a new clustering routing protocol EARP. New protocol takes into account the mobility and residual energy, it significantly improves network performance. The results of simulation show EARP is much better than CBRP routing protocol.
