MobiRoute: Routing Towards a Mobile Sink for Improving Lifetime in Sensor Networks
Improving network lifetime is a fundamental challenge of wireless sensor networks. One possible solution consists in making use of mobile sinks. Whereas theoretical analysis shows that this approach does indeed benefit network lifetime, practical routing protocols that support sink mobility are still missing. In this paper, in line with the authors' previous efforts, they investigate the approach that makes use of a mobile sink for balancing the traffic load and in turn improving network lifetime. They engineer a routing protocol, MobiRoute, that effectively supports sink mobility.
