In wireless sensor networks (WSNs), one major challenge is how to prolong the network lifetime while maintaining a certain data collection rate for resource-limited static sensors. To achieve this goal, many mobility-assisted data collection (MADC) schemes have been proposed in the literature. However, there is a lack of systematic analysis on the behaviors of the MADC models in terms of both throughput...
Recently, mobility-assisted data collection has been proposed to prolong network lifetime. However, the upper bound of throughput capacity in such mobility-assisted data collection models has not been studied. In this work, we first derive the upper bound of throughput capacity when a mobile sink is available for data collection. Given the traveling speed of the mobile sink and the required delay...
