The deficient energy supplies of Wireless Sensor Networks (WSNs) drives network designers to optimize energy consumption in various ways. Not only with regard to the energy issue, but also with respect to system performance, the authors design a local search technique for sink placement in WSNs that tries to minimize the maximum worst-case delay and extend the lifetime of a WSN, simultaneously. Since it is not feasible for a sink to use global information, which especially applies to large-scale WSNs, they introduce a Self-Organized Sink Placement (SOSP) strategy that combines the advantages of their previous works and. The goal of this research is to provide a better sink placement strategy with a lower communication overhead.
