Wireless body area networks: a comprehensive survey.

Current progress in technology, especially wireless body area network (WBAN) became one of the enabling technologies that provide many successful applications in non-medical or medical field. WBAN is a communication standard optimised for low power devices and operation on, in or around the human body, to monitor the human health issues and route the physical or vital data from biosensors nodes to the server for further analysis. The challenge of WBAN is that the energy of the biosensors is limited by the battery life and many routing protocols have been designed specifically for relaying collected data to a base station for additional processing, it might differ depending on the network architecture. This paper based on the recent publications provides a WBAN survey.

Wireless body area network for health monitoring.

A Wireless Sensor Networks (WSNs) consists basically of a group of nodes, that communicate with each other through a wireless transmission, and does not need any existing infrastructure. The recent developments in technology and wireless communication, to be used in various applications, foster the development of Wireless Body Area Networks (WBANs). They are emerging as important networks in order to reduce the need for patients, and to help the elderly and chronically ill people to live an independent life. In this paper, we propose a routing protocol for wireless body area networks, to transfer data in the network with minimum energy consumption, and longer network lifetime through multi-hop communication. The proposed protocol has been verified by performing simulations, and the obtained results show that our routing protocol ensures a robust optimisation of the energy consumption which helps to increase the lifetime of the network and its stability.

An energy efficiency routing protocol for wireless body area networks.

The wireless body area networks (WBANs) play an important role in monitoring and minimising the duration of patients stays at the hospital. The aim of our study was to design an energy efficient routing protocol for WBANs taking into consideration the minimisation of energy and maximisation of the network lifetime, such as that the routing is recognised as a resource hungry operation. In this protocol, to confront the different constraints, we use the concept of the gateway body sensor which is responsible for sending data to the base station. Some biosensors transmit data directly while some use clustering technique to send data, it depends on the type of transferred information. Simulation results showed that clustering based routing protocol for wireless body area network (CRPBA) improves the quality of our network by minimising the energy consumption and enhances the stability period.
