Neighbor Discovery in Mobile Sensor Networks
Mobile sensor nodes can be used for a wide variety of applications such as social networks and location tracking. An important requirement for all such applications is that the mobile nodes need to actively discover their neighbors with minimal energy and latency. Nodes in mobile networks are not necessarily synchronized with each other, making the neighbor discovery problem all the more challenging. In this paper, the authors propose a neighbor discovery protocol called U-Connect, which achieves neighbor discovery at minimal and predictable energy costs while allowing nodes to pick dissimilar duty-cycles. They provide a theoretical formulation of this asynchronous neighbor discovery problem, and evaluate it using the power-latency product metric.
