WBAN health care-based: Modeling Signal to Interference ratio with Different MAC Protocols

Wireless Body Area Network (WBAN) is widely used in E-healthcare system as it provides continuous monitoring on physiological parameters. However, when two or more WBANs overlap with each other, there exists inter-WBAN interference. The inter-WBAN interference may cause transmission failures. In this paper, the signal to interterfernce ratio with different medium access control protocols, such as ALOHA, CSMA/CA and CSMA/CA with reservation is modelled and derived based on the honey grid model.
