This paper proposes a secure encrypted-data aggregation scheme for wireless sensor networks. Our design for data aggregation eliminates redundant sensor readings without using encr...
Abstract— In this paper, we propose and evaluate a selforganizing communication mechanism for wireless sensor networks where a large number of sensor nodes are deployed. To accom...
The paper addresses the relay node placement problem in two-tiered wireless sensor networks. Given a set of sensor nodes in Euclidean plane, our objective is to place minimum numbe...
Abstract— A crucial issue in deploying wireless sensor networks is to perform a sensing task in an area of interest in an energy-efficient manner since sensor nodes have limited...
