For smaller scale wireless sensor networks (WSN) it has been clearly shown that a single mobile sink can be very beneficial with respect to the network lifetime. Yet, how to plan the trajectories of many mobile sinks in very large WSNs in order to simultaneously achieve lifetime and delay goals has not been treated so far. In this paper, we delve into this difficult problem and propose a heuristic...
Abstract-In this paper, we propose an efficient planarizationalgorithm and a routing algorithm dedicatedto Unit Disk Graphs whose nodes are localized usingthe Virtual Raw Anchor Coordinate system (VRAC).Our first algorithm computes a planar 2-spanner underlight constraints on the edge lengths and induces a totalexchange of at most 6n node identifiers. Its total complexity is O(n?, with ? the maximum...
