This paper studies means of archiving energy balance in Wireless Sensor Networks (WSNs) as criterion to increase network lifetime. While protocols for balancing energy through centralized computation have been established, effective solutions for more realistic distributed settings are still an open research field. In this work, we present a novel approach for balancing energy in WSNs in a distributed...
A wide range of applications in wireless sensor networks rely on the location information of the sensing nodes. However, traditional localization techniques are dependent on hardware that is sometimes unavailable (e.g. GPS), or on sophisticated virtual localization calculus which have a costly overhead.Instead of actually localizing nodes in the physical two-dimensional Euclidean space, we use directly...
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...
Evaluating target tracking protocols for wireless sensor networks that can localize multiple mobile devices, can be a very challenging task. Such protocols usually aim at minimizing communication overhead, data processing for the participating nodes, as well as delivering adequate tracking information of the mobile targets in a timely manner. In this paper we design a new localization protocol, where...
