The simulation and analysis of modified LEACH protocol for wireless sensor networks using TOSSIM

The most important routing protocol LEACH of wireless sensor networks (WSNs) has been incorporated by W. Heinzelman. LEACH uses the concept of dynamic clustering when sensor nodes are deploying randomly. Therefore the number of cluster impact on the network. This paper describes the network quality that depends on the optimum selection of number of clusterhead in Modified LEACH protocol using new simulator TOSSIM. hi this paper we discussed and explain the comparison of data packet broadcasting, energy consumption and dead node of LEACH and Modified LEACH respectively. Simulation result shows Modified LEACH performs better than LEACH for extending overall network performances.
