Abstract
The recent advancement in information technology and evolving of the (IoT) shifted the traditional medical approach to patient-oriented approach (e.g., Telemedicine/Telemonitoring). IoT permits several services including sensing, processing and communicating information with physical and bio-medical constraints. Wireless Body Area Network (WBAN) handles the issues pertaining to the medical purposes in the form of sensor nodes and connected network. The WBAN takes human physiological data as an input to subsequently monitor the patient conditions that are transferred to other IoT components for analysis. Such monitoring and analysis demand a cohesive routing approach to ensure the safe and in-time transfer of data. The temperature rise of bio-medical sensor nodes makes the entire routing operation very crucial because the temperature of implanted nodes rises and ultimately damages body tissues. This needs dispersion in data transmission among different nodes by opting various available routes while avoiding temperature rise. In this paper, we present Adaptive Thermal-Aware Routing algorithm for WBAN. The ATAR is designed to overcome the temperature rise issue of implanted bio-medical sensors nodes. The new protocol is based on Multi-Ring Routing approach to find an alternative route in the case of increasing temperature. The simulation results indicate that proposed protocol is more efficient in terms of temperature rise and throughput than existing approaches.
Highlights
Internet-of-Things (IoT) is the network of interrelated physical objects embedded with electronic, software devices and wearable sensors that efficiently collect and exchange data with each other over the network [1,2,3,4,5,6]
The low-temperature peaks for Adaptive Thermal-Aware Routing (ATAR) in the simulation are due to the reason that ATAR always selects the forwarder with minimum available temperature
In case of temperature rise of the forwarder, ATAR selects another forwarder within the ring level to forward obtained sensor readings
Summary
Internet-of-Things (IoT) is the network of interrelated physical objects embedded with electronic, software devices and wearable sensors that efficiently collect and exchange data with each other over the network [1,2,3,4,5,6]. The emerging IoT technology plays a consequential role in various walks of life e.g., business, transport, education, etc., as well as healthcare system by providing health’s facilities to the patient at low cost on his doorstep [7]. These IoT devices are harnessed to connect the patients and doctors around the world through Internet [8]. Excessive rise of various chronic and acute diseases has put the life of many people at an immense danger, which has caused many to maintain good health. Patients with chronic diseases (i.e., diabetes, heart stock, high blood pressure, etc.) are required to be monitored on a regular basis
