Performance of RSS Based Cooperative Localization in Millimeter Wave Wireless Sensor Networks

Localization in wireless sensor networks (WSNs) is a necessity as there is a vital need to have location information combined with the measured quantities. The received signal strength (RSS) based localization is a simple and a cheap model but it provides a low positioning accuracy. However, its accuracy can be enhanced by applying a cooperation mechanism among sensors. In this paper, the performance of RSS, based localization, and its cooperative version are studied, analyzed, and simulated in WSNs which operate in the millimeter wave frequency bands. Moreover, this performance is compared with that of WSNs which operate in radio bands. It can be concluded that, the positioning accuracy is high in WSNs operating in millimeter wave bands. Moreover, their performance is better than that of the corresponding WSNs operating in radio bands especially at low levels of signal to noise ratio.
