An Acceleration-based Packet Transmission Mechanism for Wireless Sensor Systems
Hansol Ji, Namgi Kim · International Journal of Bio-Science and Bio-Technology · 2015
A wireless body sensor system (WBSS) provides diverse healthcare services by attaching sensors to the arms, abdomen, and feet of a user and by swiftly obtaining the user's movement and health-related information.In order to overcome the battery limitations of sensors and the variations in wireless channels in such WBSSs, much research is being conducted.This paper aims to propose a new packet transmission power control (TPC) mechanism that judges wireless channel conditions using acceleration values and inhibits packet transmission when the channel is unstable, thereby reducing energy consumption.The TPC mechanism proposed in this paper was able to save energy efficiently while not increasing the delay time much when the channel condition changed.
