Efficient data transmission scheme for ubiquitous healthcare using wireless body area networks

Abstract

Data generated by wireless body area network (WBAN), are heterogeneous as they have different characteristics in terms of priority, transmission rate, required bandwidth, tolerable packet loss, delay demands etc; thus transmitting them in uniform fashion is unsuitable. This paper proposes an efficient data transmission scheme which classifies and prioritizes data patients according to their current status and their diseases; also we utilize multiple paths routing between the coordinator and gateway to provide a solution satisfying the delay requirements of different data types. Finally, it's shown that the proposed scheme is efficient for timely data transfer in WBAN. © 2011 Springer-Verlag.
