Cluster Head Selection Using Analytical Hierarchy Process for Wireless Sensor Networks

The cluster-based wireless sensor network (WSN) can enhance the whole network lifetime. In each cluster, the cluster head (CH) plays an important role in aggregating and forwarding data sensed by other common nodes. A major challenge in the WSN is the appropriate cluster head selection approach. In this paper, we propose a centralized cluster head selection approach using analytical hierarchy process (AHP). Three factors contributing to the network lifetime are considered and they are energy, mobility and the distance to the involved cluster centroid respectively. Simulation results demonstrate that the proposed approach is effective in prolonging the network lifetime
