Joint Sink Mobility and Routing for Lifetime ElongationThe longevity of wireless sensor networks is a major issue that impacts the application of such networks. While communication protocols have already been improved to save energy, recent results show that network lifetime can be prolonged by further involving sink mobility. Since most proposals give their evidence of lifetime improvement through numerical simulations, the following two important aspects are still missing:
In this part of the project, we are focusing on the theoretical analysis and protocol implementation related to joint sink mobility and routing for increasing the lifetime of wireless sensor networks.
Positioning Sensor Nodes with Mobility-Differentiated ToALocation-awareness is crucial to many applications of sensor networks. Existing location surveying approaches either rely on an inflexible infrastructure or suffer from high computation and communication load. In this part of the project, we present Non-intEractive lOcation Surveying (NEOS) to address certain deficiencies in the existing approaches. The key contribution of NEOS is twofold:
MDToA enables us to devise flexible and robust positioning algorithms; the resulting computational load fully obeys the processing constraints of sensor nodes. Furthermore, the non-interactive feature of NEOS allows of a substantial reduction on the nodes' energy consumption. We have implemented a preliminary prototype of NEOS using CricketMotes.
