Inter-BSN Interference Investigation for Body Sensor Netwoks

Recently, much interest has been involved in the design of Body Sensor Networks (BSNs). It is extremely desirable to maintain high reliability for BSNs. One of the main causes that deteriorate BSN performance is inter-BSN interference, which refers to the interference due to simultaneous transmission of several BSNs in the proximity of each other. This paper investigates how often and severely the inter-BSN interference exists in the common scenarios. The interference duration and the interference level are utilized as two metrics to measure the interference. The results of our simulation imply the significance of mitigating the inter-BSN interference effect. Moreover, it provides a guideline for the inter-BSN interference mitigation scheme design, and a test bed to test whether a mitigation method can be effectively applied in a specific scenario as well.
