Two Ranked Aware Phase Surveillance in Wireless Sensor Networks.
Event detection and environment surveillance are the important issues in wireless sensor networks. However,using the non-renewable power source leads to the short lifetime of the networks. For this reason the scheduling process is to determine the time sensor node wakes up and goes sleeping to conserve energy, so the delay time and the working interval would become trade-off. In this article, we introduce the two ranked aware phase surveillance to lower the delay time, and we use the sensed data to make the scheduling policy.We consider the event happening in two phase, so we propose two surveillance models to cope with these two phases,although this model is simple to create it can achieve the goal of reducing the delay time of detection and delivery. Finally, we show our performance in the simulation section and then describe the improvement of our approach in the future work section.
