A Survey on Game Theory based Interference Mitigation in WBASN

A wireless body area network (WBAN) consists of several sensors implanted inside a body or placed on a body that help in the continuous monitoring of health conditions such as heart rate. The sensor nodes transmit the data to a central controller, which serves as a gateway to transmit this information to medical servers and then finally to the hospitals for medical attention. Due to multiple body area networks operating in the same frequency band, inter-interference takes place. The WBAN’s working in a small sphere cause inter-interference resulting in packet-loss and performance degradation. Hence, interference is a complex and challenging problem. Interference mitigations are receiving immense attention from the research community but are far from creating a complete solution. Usage of game theoretic approach to address the interference issues is very promising. This survey paper presents a comparative analysis of the existing game theoretic solutions designed to mitigate interference. As per our knowledge, this is the first survey work based on the usage of the game theory approach for interference mitigation in WBANs.
