Energy-efficient Video Transmission in Wireless Body Sensor Networks

Due to continuous enhancement to safety and effectiveness in medical health a video transmission is considered as a quite significant step during first hour of the emergency event. However, the energy hungry video encoding and transmission processes and slow progress in battery technologies have become a major and serious problem for the evolution of video technology in wireless body sensor networks (WBSN). So enhancing energy-efficiency during voluminous and variable bit rate (VBR) video transmission in WBSN is a challenging and crucial problem for researchers and engineers. Therefore, the need arose to conduct research on energy-efficient battery-friendly technologies to cater the need of upcoming sensor nodes. It is reported that a significant amount of energy is consumed during communication, which shortens operation and battery lifetime of the nodes for particular applications in WBSNs. Therefore, in this context it is very vital to develop energy-efficient and battery-friendly solutions that can minimize energy-deficiency and extend battery lifetime of WBSNs. Moreover, due to large temporal variations in the wireless on-body channel, typical conventional techniques do not provide the sufficient energy saving in WBSNs.
