Comprehensive Collection

Wireless Body Area Network (WBAN) is an application of wireless sensor network (WSN). WBAN therefore forms a comprehensive collection of devices that are not only capable of providing continuous information about the health status of a person but also offers helpful details about the activities and environment of the person. In this paper, we have evaluated TDMA based MAC protocol performance through several metrics and TDMA approach is used to avoid packet collision which leads to higher packet loss rate. Reinforcement Based Clock synchronization is the solution of problem like packet collision. After clocks of WBAN sensor nodes are synchronized, data can be transferred between sensor nodes and sink efficiently and rapidly. Reinforcement learning iteratively optimizes the clock synchronization technique. Experimental results indicate that the proposed algorithm is more efficient than existing techniques.

Medium Access

Wireless body area networks (WBANs) have become a leading solution in mobile health (mHealth). Typically, a WBAN consists of in-body or around-body sensor nodes for collecting data of physiological feature. For a WBAN to provide high throughput and low delay in an energy-efficient way, designing an efficient medium access control (MAC) protocol is of paramount importance because the MAC layer coordinates nodes’ access to the shared wireless medium. To show the difference of MAC protocols between Energy-Harvesting wireless body area networks (EH-WBANs) and battery powered WBANs (BT-WBANs), this paper surveys the latest progresses in energy harvesting techniques and WBAN MAC protocol designs. Furthermore, a novel energy utility architecture is designed to enable sensor node lifetime operation in an EH-WBAN.

Scheduled Traffic

In the present era the use of e-health plays a major role in the field of medical science. Today a significant attraction interest is towards Wireless Body area network (WBAN). The major challenges of Wireless Body area network (WBAN) technique are to maintain the quality service and to track the network stability for a longer time, e.g., probability of delivery, and latency. The main important issue is to maintain the energy efficiency within the formed network. Here we propose a protocol for WBANs based on MAC using the multi-dimension (MD) graph optimization to compromise the energy consumption and QoS in data transmission. In WBANs, low battery performing on-body or inculcate biomedical sensor nodes are applicable to observe and gathers the physiological signals like body temperature, blood pressure, ECG and EEG. The MAC protocol design utilizes an optimization algorithm to optimize the scheduled traffic and channel of WBAN. The proposed protocol simulation results will be better than TDMA, CA-MAC and IEEE 802.15.6 MAC in terms of energy efficiency and QoS for large network conditions.

Wireless Medium

The increasing use of wireless communication and the continuous miniaturisation of electronics devices have brought about the concept of Wireless Body Area Network (WBANs). In these types of networks, the sensor node operates in close proximity to the body and also the wireless nature of the system presents various novel, real-time and new methods to improve health care delivery. The sensor is capable of measuring any parameter which it has been designed to read, for example the heartrate and the body temperature. This paper presents a review of the concept of WBANs with a focus on the mechanism of data communication over the wireless medium. Further, it examines ways to power such devices, in particular focusing on minimisation of energy requirements, thereby reducing maintenance demands and contributing to making the environment ‘greener’.

An interference avoidance mechanism for Chinese Wireless Body Area Network (WBAN) is proposed in this paper. This mechanism firstly classifies the channels by priority based on the distribution characteristics of potential interference on the China medical band, commits energy detection on all channels in the network initialization phase, and compares to energy threshold to form available channel set. Then differentiated channel maintenance strategy is utilized to avoid interference as far as possible in network running phase. The scheme proposed in this thesis is proved to be superior by simulation from either the interference probability or packet loss rate. Apart from that, the interference detection threshold that can satisfy the least communication demand is calculated for every Type B, C channel by simulation and convenient for referring to.
