The rapid proliferation of wireless sensor networks has stimulated enormous research efforts that aim to maximize the lifetime of battery-powered sensor nodes and, by extension, the overall network lifetime. Most work in this field can be divided into two equally important threads, namely (i) energy-efficient routing that balances traffic load across the network according to energy-related metrics...
While wireless sensor networks have important applications in many fields, the limited battery life and high deployment cost pose serious challenges. One way to maintain good coverage and extend the network lifetime is to deploy sensors in high density and schedule them to sleep between active cycles. In this paper, we propose an algorithm to schedule the sensors to sleep based on the area of overlapped...
