WBANs consist of a number of miniaturized sensors that are primarily used to monitor the patient's vital parameters over a long period of time. Those wirelessly connected sensors and actuators placed inside or around the body to introduce a continuous, effective, and unobtrusive monitoring of physiological signs to support medical applications, lifestyle, and entertainment. However, because of the coexistence of other wireless technologies as well as the presence of many WBANs in the same area, interference can occur. Since WBAN networks are used in health care applications, loss of data because of interference will be particularly dangerous for critical medical applications. Therefore, it is extremely important to mitigate this interference to ensure reliable data communication. This survey will firstly provide an up-to-date view of WBAN interference. Then, it will introduce a comparative study on the mutual interference mitigation schemes with considering the taken approach either MAC or power control.

WBAN, Coexistence, Interference, Mitigation, MAC, Power control

Interference is dangerous in WBAN networks because it affects WBANs' performance and reliability. In medical applications, it puts the patient's health at risk. Therefore, the adoption of interference mitigation plans is mandatory in WBAN design. In this survey, the coexistence of WBAN networks with respect to interference problems has been reviewed, the current mitigation plans for WBAN have been classified, and the WBAN mutual interference mitigation schemes were introduced and compared qualitatively. This survey has recommended a mitigation scheme that take the merits of the two discussed approaches, MAC approach and power control approach. Although many interference mitigation schemes are reported, there is no dominant scheme that outperforms other systems. There is a need for an analytical tradeoff between network throughput and power consumption. Quality of Service, Delay, Reliability, and network lifespan should also be considered with interference mitigation design.
