In contention-based sensor networks, nodes compete to access a shared channel for data transmission and collision is a common challenge. For power conservation, periodical active/s...
Abstract-- The emergence of nomadic applications have recently generated much interest in wireless network infrastructures that support real-time communications. In this paper, we ...
—Ultra-wideband (UWB) is a physical (PHY) layer technology that promises high transmission rates, as well as high resistance to noise and multipath effects. However, the impulseb...
In this paper, we propose a novel MAC protocol, called Quality-ofservice Guarantee Multiple Access (QGMA), in wireless local area networks to support the quality of service requir...
— Mobile ad hoc networks (MANETs) provide a powerful and dynamic platform to enable mobile computers to establish communications without an existing infrastructure. In order to p...
