Abstract—Wide research has been carried out in this Wireless Sensor Networks to improve the lifetime of the sensor nodes in order to enhance the performance of the network. Clustering hierarchical structure is the base for the most of the existing methods which significantly reduces the energy consumption of each node, but it increases the communication burden of the cluster heads. In the proposed method both the intra-cluster and inter-cluster traffic are used to reduce the load of the cluster heads. Sensor nodes and Cluster Heads are arbitrarily placed in the deterministic setup phase with the knowledge of their locations. Each Cluster Head routes its traffic directly to the sink or relays it through other Cluster Heads. In the proposed method, a power-balanced optimal clustering/routing algorithm is used, which constitutes two mechanisms, a routing-aware optimal cluster planning and a clustering-aware optimal random relay for achieving balanced power consumption. We evaluated the performance of the proposed algorithm and concluded that this algorithm outperformed existing algorithm in terms of energy consumption and longevity of network.
Keywords— Wireless sensor networks, Routing aware optimal clustering, clustering aware optimal random relay.
