Energy Efficient Broadcasting and Forward Node Selection Using Network Coding In Mobile Wireless Sensor Networks (MWSN)

摘要

In mobile wireless sensor networks (MWSN), broadcasting and forward node selection scheme may result in redundancy, collision, congestion, performance degradation, broadcast storm problem and so on. In order to overcome these issues, in this paper, we propose an energy efficient broadcasting and forward node selection using network coding in (MWSN). In this technique, the number of nodes involved in broadcasting operation is reduced by eliminating the nodes using minimum connected dominating set algorithm. Then the rebroadcast redundancy is minimized by selecting the forwarders using fuzzy logic based on the parameters such as delay, residual energy and distance. To minimize rebroadcasts, each node rebroadcast only when its coverage degree is above a threshold value. By simulation results, we show that the proposed technique minimizes the energy consumption and redundancy.
