Critical Data Routing (CDR) for Intra Wireless Body Sensor Networks

摘要: Recently, Wireless Body Sensor Network (WBSN) has been emerged as a promising technology to provide medical and healthcare monitoring. It can significantly reduce the health-care cost by providing continuous health monitoring facility elderly people suffering from chronic diseases. The life critical real time application of WBSNs requires assurance demanded Quality Service (QoS) both in terms delay reliability. This paper proposes Critical Data Routing (CDR) that categorizes sensory data packets non-critical packets. Along with heterogeneous natured data, it also addresses high dynamic path loss temperature rise issues caused postural movement human body electromagnetic waves absorption respectively. simulation results show proposed CDR scheme achieves its designed objective forwarding within certain limits highest reliability while reducing in-body sensor nodes.
