An Energy Efficient Routing Protocol under Distance, Energy and Load Parameter for Heterogeneous Wireless Sensor Networks

In wireless sensor network sensor nodes are inexpensive portable devices with limited processing power and energy resources. To maximizing the lifetime of wireless sensor network we need an effective routing approach. The proposed routing protocol uses Region-Based static clustering approach to provide efficient utilization of total coverage area and Hybrid Routing approach is used for transmitting data to base station that enhances lifetime of the network. The fuzzy logic technique is used for cluster head selection based on distance, residual energy and load parameters, minimizes the overall energy consumption among the nodes. Simulation results shows that proposed protocol improves the overall network performance in terms of throughput and lifetime.
