Abstract Recent technological advancements in miniaturization of sensor and wireless communication lead to development of Wireless Body Area Networks (WBAN). It is similar to Wireless Sensor Networks but mainly focuses on health care applications to monitor the health condition of patient continuously. It consists of implantable and wearable computing devices placed inside or outside the surface of human body for sensing and data communication. Due to continuous operation, the sensor node introduces electromagnetic radiations which causes damage to delicate human tissues as well as degrades the performance of the network. In addition, WBAN data are sensitive to delay and it is necessary to send critical patient data to the remote server in a timely manner to protect patient’s life. However, alternating the routing path of critical data leads to collision, packet loss, high power consumption, maximum delay and reduced network life time. In this paper, Optimum Path Optimum Temperature Routing Protocol is introduced to address the above issues. The proposed protocol chooses optimum routing path by determining the temperature of sensor nodes and by defining two threshold limits (minimum and maximum). It also considers the critical data signals to be sent when the temperature of node exceeds the admissible threshold limit. The obtained simulation results are compared with conventional routing protocols and was analyzed that the proposed protocol has decreased delay, minimum energy, reduced power, uniform temperature distribution and maximum lifetime of sensor node.

1 Introduction Nowadays, technological developments in remote healthcare applications and Internet of Things (IoT) [1] have gained the attraction of more researchers towards Wireless Body Area Networks (WBANs). A modern WBAN supports many integrated, advanced and personalized applications in different fields such as military, disaster relief, fitness, medical, sports etc [2]. WBANs are smart wireless networks used for continuous health monitoring of patients.

It consists of implantable/wearable computing devices fixed inside or on the human body’s surface for short range communication. A WBAN system consists of numerous tiny sensor nodes. The node’s function is to sense and measure human body’s specific parameters such as sugar level, heart beat rate, body temperature, Electroencephalography (EEG), blood pressure, Electrocardiography
