In this research paper, we propose an energy efficient routing protocol low energy adaptive clustering hierarchy (LEACH) for wireless sensor networks. There are many sensing nodes and sink nodes in wireless sensor network system. Routing protocol and its improvement is a major issue in wireless sensor networks. Our proposed protocol is the modification of LEACH. The main idea is to increase the network life and maximizes the throughput. In this research paper, residual energy is to be considered for the selection of cluster head from various nodes. Time division multiple access (TDMA) technique is used for the communication between common nodes and cluster head. Cluster head (CH) chooses code to be used in its cluster and code division multiple access (CDMA) technique is used between clusters. The comparison between improved versions of LEACH protocol shows that multi-hop LEACH shows significant improvement than energy LEACH (E-LEACH).
