چکیده
Wireless Sensor Network (WSN) consists of hundreds or thousands of sensor nodes which have limited energy, computation and memory resources. WSNs are highly affected by the energy dissipation of the nodes. LEACH is a cluster based routing for sensor networks for efficient data collection problem where small numbers of clusters are being formed in a selforganized manner. In this paper the advancement of the LEACH protocol has been done for heterogeneous networks. .We have proposed a cluster based routing protocol for heterogeneous WSN in order to minimize the energy consumption and increase the network lifetime. Simulation results using MATLAB shows that the proposed Leach-heterogeneous system significantly reduces energy consumption and increase the total lifetime of the wireless sensor network.
