Routing Algorithm of Unequal Clusters Based on ARMA Model

In this paper, An uneven clustering routing based on ARMA model(UCR-A) was proposed for the "hot spot", and the main ideal is that the entire region is divided into unequal radial level with the base station at the center. Cluster head is chosen based on the residual energy and the relative position. Multi-hop data routing was formed in inter-cluster, and apply ARMA prediction model to the cluster head nodes, thus avoiding the cluster head death because of energy depletion.At the stage of stable transmission each cluster head using dynamic routing to avoid the relay node rapid death due to excessive energy consumption. The simulations show that the new protocol proposed in this paper can effectively reduce network energy consumption, better balance the energy consumption of network nodes, significantly extending the network life period.
