A real-time MAC protocol for wireless: Virtual TDMA for Sensor (VTS)

Wireless Sensor Network(WSN)are designed for data gathering and processing, with particular requirements and constraints: low hardware complexity, low energy consumption,special trafic pattern suport, scalabity, and in some case, real time operation. In this paper we present the Virtual TDMA foe Sen...
