Abstract
This paper concerns the definition of an analytical model and of a distributed protocol, termed Greedy Maximum Residual Energy (GMRE), for determining the routes of a mobile data collector (sink) traveling through the nodes of a wireless sensor network (WSN). The routes are determined with the overall aim of maximizing the network lifetime. An ns2-based simulation comparison between GMRE, optical static sink placement and random sink mobility shows that GMRE yields remarkable improvements both for network lifetime and for balancing energy consumptions throughout the network.

Joint Sink Mobility and Node Deployment for Prolonging Lifetime in Wireless Sensor Networks
BCGIN '13: Proceedings of the 2013 International Conference on Business Computing and Global InformatizationWhen cluster heads transmit their data to the sink via multi-hop mode, the cluster heads closer to the sink are burdened with heavy relay traffic and tend to die early. In this paper, taking both sink mobility and node deployment into account, we ...

Using sink mobility to increase wireless sensor networks lifetime
WOWMOM '08: Proceedings of the 2008 International Symposium on a World of Wireless, Mobile and Multimedia NetworksA critical issue for data gathering in wireless sensor networks is the formation of energy holes near the sinks. Sensors near the sinks have to participate in relaying data on behalf of other sensors and thus will deplete their energy very quickly, ...
