| Abstract(in English) | Wireless Body Area Network (WBAN) is a communication system between wearable devices in human body area. WBAN using millimeter wave is expected to solve inter-WBAN interferenceproblem. The human body attenuation is important to reduce the interference especially in user-dense condition. In the millimeter-wave band, due to its linearity and attenuation characteristics, the number of interferers varies depending on the location of the WBAN user. However, conventional interference avoidance protocols such as Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) do not consider the variation in the number of inter-WBAN collisions. Thus, the fairness of communication opportunities in an overcrowded environment is degraded. In this paper, we propose an inter-WBAN interference avoidance algorithm that selects the optimal Contention Window (CW) size to ensure the communication time of WBAN users. The fairness and total communication time of the proposed method are evaluated by computer simulation. The results show that the proposed method can achieve high fairness even when the interference increases. |
