More and more wireless networks are deployed with overlapping coverage. Especially in the unlicensed bands, we see an increasing density of heterogeneous solutions, with very diverse technologies and application requirements. As a consequence, interference from heterogeneous sources—also called cross-technology interference—is a major problem causing an increase of packet error rate (PER) and decrease...
The low-power, low-rate ZigBee/IEEE 802.15.4 wireless sensor network (WSN) is vulnerable to the interference from a collocated wireless local area network (WLAN), which operates with considerably higher power in the same 2.4GHz Industrial, Scientific, and Medical (ISM) band. In this paper, a novel and effective Interference Aware Adaptive Clear Channel Assessment (IAACCA) technique is proposed to...
Wireless Sensor Networks (WSNs) are particular networks characterized by limited energy and computational resources and, if their transmission range is limited to a person's area, they are known as Body Area Networks (BANs). When two or more BANs are co-located and operate on the same channel, active periods can overlap and transmissions can conflict. This phenomenon, that drastically reduces performances...
In Cyber-Physical system (CPS), different wireless technologies are used, which results in cross-technology communication interference. Specifically, ZigBee networks share the 2.4GHz ISM band with WiFi but have much lower transmission power. Thus, the ZigBee networks inevitably suffer the interference from WiFi Networks. This paper focuses on the locality of WiFi interference and proposes an interference...
