TAEO-A Thermal Aware & Energy Optimized Routing Protocol for Wireless Body Area Networks

Abstract

Wireless Body Area Networks (WBANs) are in the spotlight of researchers and engineering industries due to many applications. Remote health monitoring for general as well as military purposes where tiny sensors are attached or implanted inside the skin of the body to sense the required attribute is particularly prominent. To seamlessly accomplish this procedure, there are various challenges, out of which temperature control to reduce thermal effects and optimum power consumption to reduce energy wastage are placed at the highest priority. Regular and consistent operation of a sensor node for a long-time result in a rising of the temperature of respective tissues, where it is attached or implanted. This temperature rise has harmful effects on human tissues, which may lead to the tissue damage. In this paper, a Temperate Aware and Energy Optimized (TAEO) routing protocol is proposed that not only deals with the thermal aspects and hot spot problem, but also extends the stability and lifetime of a network. Analytical simulations are conducted, and the results depict better performance in terms of the network lifetime, throughput, energy preservation, and temperature control with respect to state of the art WBAN protocols.

Energy Optimized Congestion Control-Based Temperature Aware Routing Algorithm for Software Defined Wireless Body Area Networks

“…The performance of the proposed EOCC-TARA is compared with the existing routing algorithms, namely E-OCER [22], TAEO [24], and PCAR [29] to estimate the superiority of the proposed algorithm for SDN-based WBAN in terms of energy, temperature, and congestion control aspects. The performance metrics used are energy consumption, network lifetime, throughput, temperature control, congestion overhead, delay, and successful transmission rate.…”

“…The comparison is to analyze the superiority or inferiority of the proposed approach for the routing in WBAN. Figures 9, 10, 11, and 12 visualize the hop count, queue length, packet delivery ratio, and delay comparisons, respectively, of the proposed EOCC-TARA with the existing E-OCER [22], TAEO [24], and PCAR [29]. It can be seen from the figures that the proposed EOCC-TARA has outperformed the other models with improved performance.…”

“…EOCC-TARA has less hop counts, less queue length, less delay, and improved packet delivery ratio. Figures 13 and 14 visualize the network lifetime and the number of dead nodes comparisons, respectively, of the proposed EOCC-TARA with the existing E-OCER [22], TAEO [24], and PCAR [29]. It can be seen from the figures that the proposed EOCC-TARA has a higher lifetime and a reduced number of dead nodes than the existing algorithms.…”

“…However, this model does not employ adaptive weighted selection for choosing the next-hop node and it may lead to over-exhaust nodes and increased hot-spot nodes. Javed et al [24] introduced a thermal aware & energy-optimized (TAEO) routing protocol for WBAN using the detection model to identify the hot-spot nodes. This approach reduced the energy consumption through reduced usage of hot-spot nodes and enhanced the overall network lifetime and throughput of WBAN.…”
