In battery powered systems such as wireless sensor networks, energy efficiency is one of the most important system design goals. In this paper, energy efficiency is examined fro...
Abstract. Recent researches on energy efficient coverage configuration in wireless sensor networks mainly address the goal of 100% or near 100% coverage preserving. However, we fin...
Wireless sensor networks have attracted increasing attentions considering their potentials for being widely adopted in both emerging civil and military applications. A common prac...
Abstract— Providing end-to-end data security, i.e., data confidentiality, authenticity, and availability, in wireless sensor networks (WSNs) is a non-trivial task. In addition t...
We study the multicast problem in wireless sensor networks, where the source can send data to a fixed number of destinations (actuators) at a different rate (multiratecast). A typi...
