Modeling and analysis of the gateway node in body sensor networks

The paper suggests a model for implementation of a body sensor network´s gateway functions. The gateway is based on a mobile smartphone with a Linux kernel. Analysis on traffic management schemes based on different queue disciplines is presented in the paper. Since the gateway is modeled as a standard mobile device, the typical traffic flows for such devices are taken into account and their influence on the medical sensors data flow traversing through the gateway is considered. The paper presents the results from experimental analysis on performance parameters. Testbed experiments are conducted on a Nexus One smartphone platform and Linux traffic control tool.
