“…Unlike DCM, InterACS applies only the switching channel into WBASNs to mitigate interference without considering packet loss. In InterACS [ 26 ], the framework for interference records the node’s activity and status, and the coordinator selects the channel based on the current SIR value to avoid collision. Although this algorithm is simple and standard, it ensures inter-WBASN interference.…”

“…Although this algorithm is simple and standard, it ensures inter-WBASN interference. However, the simulation in [ 26 ] was run with low-density WBASNs. Therefore, it is necessary to investigate the performance of InterACS in a high-density WBASN scenario.…”

“…It has been shown by experimentation that the transmission efficiency of the lightweight and robust interference mitigation scheme (LRIM) [ 27 ] is suitable for application. As with InterACS [ 26 ], LRIM applies channel hopping to avoid interference. However, LRIM is more effective than InterACS because of channel sensing.…”

“…Interference between WBASNs can be monitored by using an interference framework that decides to switch the operating channel of interfering WBASNs to another channel [ 26 ]. An interference framework includes a set of network nodes, a set of device state models, and the interface interconnecting them.…”

A wireless body area sensor network (WBASN) consists of a coordinator and multiple sensors to monitor the biological signals and functions of the human body. This exciting area has motivated new research and standardization processes, especially in the area of WBASN performance and reliability. In scenarios of mobility or overlapped WBASNs, system performance will be significantly degraded because of unstable signal integrity. Hence, it is necessary to consider interference mitigation in the design. This survey presents a comparative review of interference mitigation schemes in WBASNs. Further, we show that current solutions are limited in reaching satisfactory performance, and thus, more advanced solutions should be developed in the future.

As an important coexistence technology, channel hopping can reduce the interference among Wireless Body Area Networks (WBANs). However, it simultaneously brings some issues, such as energy waste, long latency and communication interruptions, etc. In this paper, we propose an enhanced channel hopping mechanism that allows multiple WBANs coexisted in the same channel. In order to evaluate the coexistence performance, some critical metrics are designed to reflect the possibility of channel conflict. Furthermore, by taking the queuing and non-queuing behaviors into consideration, we present a set of analysis approaches to evaluate the coexistence capability. On the one hand, we present both service-dependent and service-independent analysis models to estimate the number of coexisting WBANs. On the other hand, based on the uniform distribution assumption and the additive property of Possion-stream, we put forward two approximate methods to compute the number of occupied channels. Extensive simulation results demonstrate that our estimation approaches can provide an effective solution for coexistence capability estimation. Moreover, the enhanced channel hopping mechanism can significantly improve the coexistence capability and support a larger arrival rate of WBANs.
