A comparative study of short range wireless sensor network on high density networks

ZigBee, Wibree, Z-Wave, and RuBee are four protocol standards for short range wireless communications with low power consumption. From an application point of view, ZigBee is designed for reliable wirelessly networked monitoring and control networks, RuBee is proposed for high security applications and use in harsh environment, Wibree considered for sports and healthcare while Z-Wave is planned for residential control systems. In this paper, after an overview of the mentioned four short-range wireless protocols, we attempt to make a preliminary comparison of them and then specifically study their radio frequency, data coding, security etc. At last we have compared different protocols capabilities in high density network.
