Abstract
In Mobile Wireless Sensor Networks (MWSNs) where mobile sensor nodes densely exist, it is desirable to gather sensor data from the minimum number of sensor nodes which are necessary to guarantee the sensing coverage in order to reduce communication traffic. In the past, we have proposed a data gathering method using mobile agents in dense MWSNs. However, since this method assumes that only one sink is present in a network, it cannot effectively reduce traffic in environments where multiple sinks exist. In this paper, we propose a mobile agents control scheme which guarantees multiple sinks’ coverages and efficiently gathers sensor data. In the proposed method, mobile agents are communalized if their sensing points overlap, and sensor data are aggregated to transmit them to same direction.
