Remote Patient Monitoring System Based Coap in Wireless SensorNetworks

Patient monitoring is a process of collecting medical parameters of a patient present at a remote location. To deal with this particular issue in a hospital or medical assistance centre, this paper proposes an alternative vision that includes support through internet based on wireless networks and also compatible with existing infrastructure. Most of the existing paper deals with monitoring through sophisticated hardware in a private network and each have its own overheads of switching to a new system model. This paper deals with the enhanced Constrained Application Protocol (CoAP) using multi hop flat topology, which makes the patients being monitored by a central system. It also provides secure communication among the patient nodes by using the public key algorithm. We aim to minimize as well improve implementation method more domestically and secure communication between client and server.
