Abstract
People normally live in community and often work in group, and the WBAN applications intends to reinforce this way of living. WBAN subjects as persons should interact cooperatively each other by providing information redundancy, better coverage, etc. and so improve the WBAN's quality of service. As WBAN subjects are likely to move, the localization service is important for emergency, guidance, securing etc. The main goal of this thesis is to o er to a user a system with a high quality, that should ensure the quality of intra/inter-WBANs transmissions, be less energy consumer and adaptable to changes of environment. To ful ll these requirements, cooperation mechanisms are a chosen as solution and localization service is studied due to mobility e ects.
Apart from a survey on WBAN technology, applications and services, and WBAN based monitoring systems projects, this thesis encompasses three main parts:
The rst part proposes a 4-tiers architecture for WBAN-MS to sustain mobility. It is a really improvement of a 3-tiers architecture mostly used for healthcare monitoring systems.
Noticing that there is so far no mechanisms proposed for tra cs going out of WBAN, it is proposed to implement at the coordinator a Priority Weighted Round Robin (PWRR)scheduling technique to bridge sensitive data from WBAN to peer-networks.
The second part deals with the intra-WBAN and inter-WBANs cooperation. For this end, a Decode and Merge cooperative MAC mechanism is de ned for intra WBAN and a NetBAN, a concept of network of BANs, is designed for inter-WBANs cooperation with a routing protocol to optimize energy consumption.
The third part undergoes the localization problem in WBAN. Thus, from a survey on WBAN localization mechanisms, a comparative study was done fallowed by a cooperative technique based on body posture detection is given. It is also proposed a kridged ngerprinting mechanism for WBAN indoor localization and a localization technique based on Kalman lter and kriging using environmental data for WBAN outdoor localization.
Finally, new horizons are described as open issues.
