报告题目：Mobile Elements in Wireless Sensor Networks
报告摘要：Data collection is one of the main applications of wireless sensor networks. Traditional ways to such an important task use either direct transmissions to the sink node, forcing further away nodes to consume their on-board energy excessively, or multi-hop forwarding, while imposing heavy traffic to the nodes around the sink, both leading to a shorter network lifetime. Mobile elements introduce a new dimension to reducing and balancing the energy consumption of sensor nodes, however, they also increase the data collection latency due to the limited travel speed. In this talk, we present a progressive optimization approach to data collection in wireless sensor networks with mobile elements, and extend it to the scenario with multi-rate wireless communications. We also investigate the performance of data collection with mobile elements in an online scenario where the data collection requests and thus their locations only arrive progressively, and show such an approach to applications beyond data collection, such as wireless recharging. This is a joint work with Prof Liang He at the University of Colorado, Denver, CO, USA.
