Survey on Game Theory Approach in Wireless Body Area Network

摘要

A Wireless Body Area Network (WBAN) is used to collect biological signals from human body with the help of medical equipment and sensors that are connected wirelessly and they are placed outside or inside the body for different no-nmedical and medical applications. The standard developed for WBAN is IEEE 802.15.6. The rapid enhancement of Body Sensor Networks (BSNs) provides continuous health monitoring to control patient’s life as they play important role for saving life of patient’s by utilizing several variety of sensors that are used in the health care applications. These sensors monitor continuously different biological functions such as blood pressure, temperature, Electrocardiogram(ECG), heart rate, Electroencephalogram (EEG) etc. The data which is collected are transmitted the information at regular intervals to a central hub. The patient’s health monitor in real-time is the primary goal as it helps to design and support several non-medical applications such as detection of gesture for interactive games, cognitive, movement and recognition of emotions during drive assistance etc. However, WBAN application concept is still a exigent post to be considered for several technical demands like energy efficiency, lifetime of network, security, criticality of data, network throughput and prioritization. Hence, most of the WBANs utilizes wireless channel for process of communication in which these typical sensors with single transceiver device transmits the information with low power by utilizing a single /multi-channel by game theoretic approach in WBAN. In this paper, an attempt has been made to explain different types of game theoretic approaches used in WBAN.
