Abstract. In the recent years, Wireless Sensor Network (WSN) has become a great field of interest for scientific community. This novel kind of network provides a panoply of applications in different areas of human life. However the WSN must ensure the quality of service (QoS) to give the requested performance for the final user. Among different techniques presented in the literature to provide the QoS, the multipath routing is commonly used. Nevertheless this solution may become a serious problem if the multipath routing design does not consider the phenomena of interference. Indeed the constructed paths can have a zone of interference, and mainly a shared carrier sense range. In this paper we show by analytical and experimental results that using multipath technique can never overshoot the performance of single path when the interferences are not taken into account. Also we show how the carrier sense range can influence the network performance.
