Sink mobility protocols for data collection in wireless sensor networks
TL;DR: This work proposes four characteristic mobility patterns for the sink along with different data collection strategies and demonstrates that by taking advantage of the sink's mobility, it can significantly reduce the energy spent in relaying traffic and thus greatly extend the lifetime of the network.
