Implementation of Enhanced LEACH Protocol for Energy Efficient Routing in WSN

The wireless sensor network consists of a large number of small sensing nodes, this sensing node having very restricted small energy. In this type of network, energy consideration is a crucial issue and this is very important for designing this type of protocol. This paper gives a detailed idea how to improve the energy factor and it give a brief overview of the previous LEACH protocol and Advanced LEACH protocol which having very good result as compared to previous LEACH. In advanced protocol the cluster head is choosing at every single round, the node which having more residual energy in particular cluster as compare to all nodes that node automatically selected as a cluster. By this new technique we energy consumption in the network becomes low and indirectly it increases a network lifetime. The delay value, throughput value also indicates that advanced LEACH is very good result than previous LEACH protocol.
