Dynamic data collection algorithm with a mobile element in wireless sensor networks

초록

To improve energy efficiency in wireless sensor networks, there are lots of research efforts. In this paper, we utilize the notion of mobile element (ME), which moves and gathers data from sensors within communication range. And sensors resident in nearby area would form a cluster and select one among them to be their cluster node (CN). To determine the tour of ME, we first devise urgent message-based tour selection algorithm, and then supplement it by considering old CNs which do not generate any messages. © Springer-Verlag Berlin Heidelberg 2014.
