A wireless body area network (WBAN) consists of several sensors implanted inside the body or placed on the
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, interinterference 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 the comparative
analysis of existing game theoretic solutions designed to mitigate interference. As per our knowledge, this is the first
survey work based on usage of game theory approach for interference mitigation in WBANs.
