Wireless sensor network protocol for patient monitoring system

In this paper, an efficient routing protocol for patient monitoring system in rural areas was proposed using wireless sensor network (WSN) so that the patients can be treated within less time. In this system, a village with GSM network is considered and the people in that village are continuously monitored using AMON sensor, an advanced medical monitoring and alert system. All the AMON's work in ADHOC region and one AMON in the village will work in GSM network acts as a gateway between the other sensors and BS. According to the patient's condition the information has to be sent to base station (BS). In this scenario, the routing of information is based on condition of the patient so on demand or reactive routing protocols are used. Different reactive routing protocols AODV, DSR are studied and modifications are done in them and compared to find the best protocol. Routing is done based on the efficient routing protocol and by simulation it is shown that the routing protocol is best in terms of throughput, end to end delay compared to other protocols.
