Abstract

The energy consumption in wireless sensor networks is a significant matter and there are many ways to conserve energy. The use of mobile sensors is of great relevance to minimize the total energy dissipation in communication and overhead control packets. In a WSN, sensor nodes deliver sensed data back to the sink via multi hopping. The sensor nodes near the sink will usually consume more battery power than others; consequently, these nodes will quickly drain out their battery energy and decrease in the network lifetime of the WSN. The presence of mobile sinks causes increased energy reduction in their proximity, due to more relay load under multi hop communication. Moreover, node deployment technique can also be used to improve the life time of the network. Performance comparisons have been done by simulations between different routing protocols and our approach show efficient results.

Conclusions

The paper investigated Random deployment node in a square area, predetermined deployment of node in rectangular grid and hexagonal grid deployment strategy along with mobile sink that have significant advantages to enhance the network lifetime of wireless sensor network. Hexagonal grid deployment show better result because coverage and connectivity is maintained. The simulation results show dominance of predetermined node deployment strategy and sink mobility over random node deployment. Finally the simulation results are compared with one of the existing strategy taking network lifetime and energy as performance metrics.The comparative results improves the network lifetime as well as energy consumption.
