Improved LEACH Protocol with Cache Nodes to Increase Lifetime of Wireless Sensor Networks

摘要

The wireless sensor network is the decentralized type of network in which sensor nodes sense information and transmit to base station. The energy consumption is the major issue of wireless sensor network due to small size of sensor nodes and far deployment of the network. In this research paper, the Improved LEACH protocol is further improved by deploying cache nodes in the network. In the Improved LEACH protocol with cache nodes, the cluster head are selected on the basis of distance and energy. The cluster heads transmit data to cache node which is nearest and has minimum access time. The simulation of proposed modal is done in MATLAB. To validate the results of Improved LEACH protocol is compared with Improved LEACH protocol with cache node.
