Data classification and scheduling for sensor virtualisation scheme in public healthcare system

Abstract

It is really surprising that most of the sensor nodes in wireless sensor network WSN remain idle for maximum period of its lifetime resulting underutilisation of resources. There are many ongoing researches to utilise WSN resources in an efficient way. Virtualisation of sensor network VSN is one of the novel approaches to utilise physical infrastructure of WSN. VSN can be simply defined as the virtual version of WSN over the physical sensor infrastructure. By allowing sensor nodes to coexist on a shared physical substrate, VSN may provide flexibility, cost effectiveness and manageability. This paper proposes quality of service QoS aware data classification and scheduling framework for VSN in the healthcare sector. We develop a tiny virtual machine called VSNware for healthcare application which facilitates QoS aware data classification and scheduling ensuring reliability, delay guarantee and speed. Simulation results also show that proposed scheme over performs conventional WSN approaches.
