Prolonging the Lifetime and Optimizing the Energy of Wireless Sensor Network System using Mobile Sensor Nodes

As the technology of wireless sensor networks become increasingly matured and supported by small, micro-mobile devices fully, wireless sensor network has gradually become an effective tool for gathering data in various situations. It has very broad application prospects and great potential value in many areas such as in the military & national defense, environmental monitoring, biomedical, remote monitoring dangerous areas & so on. In this paper, we developed simulated an energy efficient mobile sensor node clustering protocol for WSN systems – EEMSNCP, a protocol architecture for energy efficiency, data aggregation & transmitting aggregated data to base station to achieve good performance in terms of energy efficiency and network lifetime. EEMSNCP includes self organization of sensor nodes, rotation of cluster head positions to evenly distribute energy load among all the nodes, TDMA scheduling for energy efficiency & replacement of cluster head with mobile sensor node when its energy gets depleted to improve system lifetime. Our results show that EEMSNCP improves system lifetime by an order of magnitude compared with LEACH.
