H-LEACH Protocol with Fault Tolerance in WSN

Abstract: The wireless sensor network is the type of networks in which sensor nodes sense the network information and pass the sensed information to the base station. Due to small size of the sensor nodes, the battery of the sensor nodes is very limited. In the recent times, various techniques has been proposed which will reduce energy consumption of the wireless sensor networks. In this paper, we evaluate and analyze H-LEACH protocol which is the combination of HEED and LEACH protocol. In this we apply Boltzmann learning technique to select intermediate node between Cluster Head and the Base Station for fault tolerance and to increase the network lifetime. The simulation results show that our method has less delay, energy consumption, less packet loss and high throughput.
