“…W1:(3,1), W2:(4:2), W3:(4,0) and W4:(4,2) have already been set and W3 is set in slot 11 instead of 7 which is an offset of 4 slots (Each slot is a aBaseSuperframeDuration). At the time we want to set W5: (3,0) it cannot fit in the S2frame without using an offset, so it will be put in slots 8 and 16. But this whole scenario is equivalent to Figure 5.b where no offsets are used.…”

“…Multiple interference detection schemes have been studied before. Methods based on RSSI (Received Signal Strength Indicator) and LQI (Link Quality Indicator) have been proposed [3], yet [10] shows that these measurements vary significantly in different situations and are not reliable as accurate indicators of coexistence. Other methods have been proposed based on the reception of ACKs, beacons and test frames [3] which are custom designed and don't fit into the IEEE 802.15.4 standard.…”

Using the promiscuous mode of the standard is the most trivial way of detecting coexisting WPANs; however every incoming packet has to be processed and the transmitter has to be kept on which makes it inefficient regarding power consumption.…”

“…At the highest level, the problem may be classified as homogeneous and heterogeneous coexistence. As low-power wireless transmissions (like IEEE 802.15.4) may be intensely affected by high-power ones (like IEEE 802.11), there have been numerous researches published in the area of the interference between different types of wireless technologies which can be referred to as the heterogeneous coexistence [3].…”

Wireless Body Area Networks (WBANs) comprise a fast growing technology that enables remote monitoring of vital signs and is aimed at providing support for healthcare services. These systems normally use low-power wireless technologies, such as IEEE 802.15.4, which are limited in bandwidth and range. The dense population of patients in places like hospitals is likely to raise situations where the coexistence of multiple WBANs results in severe loss of performance and functionality. Therefore providing coexistence mitigation mechanisms for this kind of systems is a necessity. In this paper, we present the performance analysis of a simulated mechanism designed to mitigate the harmful effects of coexistence on the operation of IEEE 802.15.4 based WBANs. The distributed and collaborative design of this scheme makes it well suited for typical healthcare applications. The proposed mechanism detects the coexistence situation and reorganizes the communication of the coexisting WBANs. We implement the proposed scheme and show the simulation results using OPNET.

“…Significantly interfered environment could cause severe performance degradation to the sensor network. General conclusion obtained from a number of studies shows that there is certainly coexistence issue within the 2.4 GHz ISM band and the IEEE802.15.4 devices tend to have severe impact from other systems especially the IEEE802.11 devices operating on an overlapping frequency band in the same area [1] [2].…”

Interference is one of the major factors influencing system performance of Wireless Sensor Networks (WSNs). This issue needs a serious attention, since WSNs are typically operating on the shared and unlicensed spectrum band. In other words, interference may not be controllable especially under the coexistence of devices operating with different standards within the same area. Collection Tree Protocol (CTP) is a routing protocol that is able to support large scale WSNs. With its ability, low level interference can be overcome by the routing process. This paper proposed an adaptation of CTP, so called multi-channel CTP, which provides higher system tolerance to the interference by allowing the multiple channel usage on top of the routing ability. The proposed system is evaluated via system level simulation and the results show the system performance enhancement under severe interference scenario in comparison with the traditional CTP.

With the development of technology for the Internet of Things (IoT), a large number of mobile, intelligent sensors are being connected to the Internet. The IoT is a heterogeneous environment. In industrial environments, wireless technologies coexist on the same frequency and generate different kinds of traffic. The use of different wireless technologies that are not designed to be compatible with each other causes an external interference problem, which degrades the system performance. The medium access control (MAC) sublayer protocols must be carefully designed to overcome such a problem. The time‐slotted channel‐hopping (TSCH) mode, which is dedicated for industrial applications, can mitigate such a problem because it uses the channel‐hopping technique. Because these channels are subjected to different levels of interference, this may greatly degrade the system performance when wireless sensors with mobility devices hop blindly from one channel to another. This paper improves the reliability of communications of the TSCH MAC sublayer protocol, proposed by the IEEE 802.15.4e standard, in wireless sensor networks, by applying a new, dynamic blacklisting technique. The technique selects and uses only high‐quality channels and blacklists those with low quality. The proposed solution has been simulated using Network Simulator 3. The results show significant improvements in terms of throughput, energy, and reliability.
