A 4-tiers architecture for mobile WBAN based health remote monitoring system

Nowadays, remote monitoring systems (RMS) attract much attention for their usefulness in many fields of application such as in medical or terrain monitoring, sport, military etc. Thereby, many projects have been initiated and developed especially in health domain defining thus different architectures. As the RMSs are heterogeneous, their system model requires rigorous connections between involved modules and a non-dependent architecture of application should offer many advantages. This paper proposes 4-tiers architecture for health RMS to allow mobility of mobile tiers. On the one hand, it includes a traffic classes mapping function between WBAN and peer-networks. On the other hand it proposes the implementation of a priority weighted round robin scheduling technique at the coordinator for emergency and medical data with also vertical handoff decision making algorithm to sustain the mobility, what is so far the first suggestion according to our knowledge. Results of analysis and simulations show the impact of this architecture on the system in terms of mobility, end-to-end delay in peer-networks and waiting time especially for time-sensitive data flows.
