Abstract

Background and Objectives:Body Area Networks (BAN) is an example of a Wireless Sensor Network (WSN) that includes several small electronic sensors that are placed inside or outside the human body. By collecting information and sending it to medical centers, these sensors can significantly help patients, the elderly and reduce treatment costs. One of the challenges in these networks is routing emergency packages to send to medical centers.
Methods: To reduce the delay of sending packets in the proposed protocol, packets are divided into two categories: emergency and normal. In order to send emergency packages, in addition to the delay of the nodes, we have also considered the traffic so that the packets are sent from the route with less delay and traffic. To send normal packets, the path with the most energy is selected from the shortest possible paths. In this research, we simulated the proposed algorithm using MATLAB software.
Results: The analysis and simulation results of the proposed algorithm show that the delay of sending emergency packets in the proposed protocol is 34% improved compared to the other protocols.
Conclusions: In this study, we have expressed the importance of sending emergency packets as quickly as possible in the body's wireless sensor networks, and by providing a delay-sensitive routing protocol, we have been able to delay the delivery of emergency packets compared to previous protocols.
