A new routing algorithm in cluster-based wireless sensor networks with mobile sinks

Abstract

The greatest challenge in senseor networks is the constraint on energy. Therefore, how to minimize the energy consumption while maintaining an extended network lifetime becomes the most critical issue when it comes to the design of the mobile base station for the wireless sensor networks. Sensor nodes nearby to the sink disperse large amount of data to the sink with less energy consumption while the nodes far away from the sink require more energy to do the same. A key advantage of incorporating mobile sinks into the design of a sensor network is that it may enable the gathering of timely information from remote deployments and may also potentially improve energy efficiency. The best position to locate the sink is determined at begining of each round and then sink move to based onrandom waypoint model.
