A dynamic self-adaptive routing update algorithm for MANET

Recent routing algorithms based on clustering mechanism in mobile ad hoc networks (MANET) mostly adopt the hybrid routing strategy whose routing update process only performs in local network (or in cluster). In this paper, we proposed an improved routing update algorithm, a dynamic self-adaptive routing update algorithm based on clustering mechanism. It processes intra-cluster update through clusterhead nodes and processes inter-cluster update through clusterhead and gateway nodes, therefore it controls the routing overhead while gets relatively exact global routing information.
