Abstract— We consider an unreliable wireless sensor gridnetwork with n nodes placed in a square of unit area. We are interested in the coverage of the region and the connectivity...
In this paper we propose an improved alternative for the path key establishment phase of bootstrapping in a sensor network. Our scheme lets the network adapt to the deployment conï...
Distributed localization in wireless sensor networks has attracted significant interest in recent years. In this paper, we propose two improvements towards the DV-Hop algorithm: th...
We present the definition and performance evaluation of a protocol for building and maintaining a connected backbone among the nodes of a wireless sensor networks (WSN). Building ...
—The paper addresses the maximal lifetime problem in sensor-target surveillance networks. Given a set of sensors and targets in an Euclidean plane, each sensor can watch all targ...
