Performance evaluation of channel capacity in Wireless Sensor Networks using ISM band in dense urban scenarios

Abstract

Nowadays the deployment of Wireless Sensor Networks (WSN) is rapidly increasing specially in dense urban scenarios, due to upcoming new technologies based on Internet of things. In this context, the presence of WSN, Wi-Fi and Bluetooth sharing the ISM band, could cause unsuspected interference levels that could deteriorate channel capacity in WSN and consequently deteriorate the performance of WSN and other wireless systems. Viewing this future perspective, this paper sees the importance of evaluating the performance of WSN under dense urban scenarios considering chaotic interference conditions. For this reason, a Manhattan type scenario with different concentration of WSN and Wi-Fi devices is selected and analyzed in order to detect the existence of severe interference problems for WSN channel capacity under dense urban scenarios.
