Abstract

This paper proposes a detection scheme of a selfish node in a wireless body area network (WBAN) utilizing CSMA/CA (Carrier Sense Multiple Access / Collision Avoidance) defined in IEEE 802.15.6. In the Internet of Things (IoT) era, the existence of a selfish node giving disadvantage to the network by acting selfishly is a problem. Especially, its influence is large in a WBAN dealing with medical and healthcare information. Hence, we proposed a detection method of such a node. Specifically, we focused on an illegal act of arbitrarily changing parameters of CSMA/CA in IEEE 802.15.6. In the proposed method, the illegal act was detected using measured values of back-off time. As a result of computer simulations, it was found that the detection effect can be enhanced by selecting the ratio of measured values according to the assumed illegal act and environment.
