Abstract: Wireless Sensor Networks (WSNs) are adhoc networks, consisting of distributed devices (motes) using sensor nodes to monitor physical or environmental conditions at different locations. Devices in a WSN are resource constrained; they have low processing speed, storage capacity, and communication bandwidth. In most settings,the network must operate for long periods of time, but the nodes are battery powered, so the available energy resources limit their overall operation. It is a great challenging aim to design an energy efficient routing protocol, which can minimize the delay while offering highenergy efficiency and long span of network lifetime. In this paper, we study the impact of heterogeneity and survey different clustering algorithms for heterogeneous WSNs; highlighting their objectives, features, complexity, etc. Then proposed the TSEP routing protocol for prolong the lifetime of a WSN and compared the result with basic distributed clustering routing protocol LEACH (Low Energy Adaptive Clustering Hierarchy). Simulation results using MATLAB are showed that the TSEP hetrogeneous system significantly reduces energy consumption and increase the total life time of the wireless sensor network compared with LEACH.
