This LEACH is a widespread protocol in wireless senor networks to reduce the energy dissipation of wireless sensor system. However, through the analysis, the authors found there are still some limitations in this protocol. In this paper, they propose a revised LEACH algorithm called Multi-Local LEACH to address these problems, which incorporates multi-hop and internal rotation mechanism to the convention LEACH. The authors establish the simulation platform in a virtual wireless environment by matlab and simulate the operations of the two protocols. The result of experiments shows that Multi-Local LEACH can significantly extend the network lifetime and be superior in energy saving compared with conventional LEACH.
