Abstract
Typically, wireless sensor network (WSN) uses static sinks to gather sensor data. However, it brings not only excessive sink installation cost but also energy-hole problem. In this paper, we consider data acquisition with guaranteeing latency in WSN by multiple mobile sinks. In particular, we optimize the number of sinks as well as the itinerary of each sink for this problem such that the total cost, incurred by these two factors, is minimum. We also conduct extensive simulations to evaluate the performance and efficiency of our proposal.Keywords
