Abstract: In recent years, there has been a growing interest in wireless sensor networks. One of the major issues in wireless sensor network is developing an energy efficient routing protocol. LEACH is very effective in enhancing nodes’ lifetime from

One of the most critical issues in the wireless sensor networks is the network s nodes limited availability of energy. The network lifetime strictly depends on its energy efficiency. Clustering is a method to make the consumed energy efficient. LEA

The sensor nodes of a wireless grain depot surveillance system are deployed in crystal grids, which provide lot of valid position information. To avoid the energy consumption unbalance of the single hop routing model adopted by LEACH prot

In our work we extend the LEACH s cluster head selection algorithm in WSN based on different node characteristics like, density, centrality and energy. This paper focuses on increasing the lifetime of wireless sensor networks.
