Data gathering is a basic activity of many wireless sensor network applications. We propose a novel collaborative data gathering approach utilizing data co
We study the energy consumption of individual links in wireless sensor networks (WSN). Three widely used digital modulation schemes, i.e. MQAM, MPSK, and MFSK, are analyzed and com...
— This paper considers two important issues for video sensor network, (1) timely delivery of captured video stream and (2) energy-efficient network design. Based on network calc...
Ad hoc sensor networks consist of large number of wireless sensors that communicate with each other in the absence of a xed infrastructure. Fast self-reconguration and power eci...
— Simulation can be an important step in the development of software for wireless sensor networks and has been the subject of intense research in the past decade. While most prev...
