An energy efficient coverage guaranteed greedy algorithm for wireless sensor networks lifetime enhancement
AbstractOne of the most significant difficulties in Wireless Sensor Networks (WSNs) is energy efficiency, as they rely on minuscule batteries that cannot be replaced or recharged. In battery-operated networks, energy must be used efficiently. The network lifetime is an important metric for battery operated networks. Several approaches are available to improve the network lifetime; such as data aggregation, clustering, topology, scheduling, rate allocation, routing, and mobile relay. Therefore, in this paper, the authors present a method aimed at improving the lifetime of WSN nodes by using a greedy algorithm. The proposed Greedy Algorithm method is used to extend the network's lifetime by dividing the sensors into a number of disjoint sets while satisfying coverage requirements. Comparatively the proposed greedy algorithm has improved network lifetime than heuristic algorithms. The method was able to generate a greater number of disjoint sets.
