—In this paper, we describe and analyze the design of a joint Transport, Routing and Spectrum Sharing (TRSS) optimization algorithm for wireless networks with frequencyagile radi...
Abstract—Employing multiple base stations is an attractive approach to enhance the lifetime of wireless sensor networks. In this paper, we address the fundamental question concer...
In a tree-based ZigBee network, ZigBee routers (ZRs) must schedule their beacon transmission times to avoid beacon collisions. The beacon schedule determines packet delivery laten...
Delivering sensed data to the sink reliably in sensor networks calls for a scalable, energy-efficient, and error-resilient routing solution. In this paper, a reliable energy-effic...
