Designing insistence-aware medium access control protocol and energy conscious routing in quality-of-service-guaranteed wireless body area network

Abstract

Wireless body area network is a type of wireless sensor network that enables efficient healthcare system. To minimize frequent sensor replacement due to resource restrictions, it is necessary to improve energy efficiency in wireless body area network. This article deals with energy efficiency and quality-of-service improvement together in novel wireless body area network architecture. A novel wireless body area network architecture is designed with dual sink nodes in order to minimize delay and energy consumption. A novel insistence-aware medium access control protocol which is aware of criticality of sensed data is presented in the proposed wireless body area network. Prior knowledge-based weighted routing algorithm is responsible to select optimal route for data transmission. In prior knowledge-based weighted routing, weight value is computed by considering significant metrics such as residual energy, link stability, distance, and delay in order to improve energy efficiency and quality of service in the network. Energy consumption is further minimized by incorporating graph-based sleep scheduling algorithm. In graph-based sleep scheduling, criticality of sensor node is also considered as major metric. In coordinator, split and map-based neural network classifier is involved to perform packet classification. After classification, packets are assigned to corresponding sink node according to packet type. Then, throughput and delay metrics are improved by frame aggregation process which is involved in sink node. Extensive simulation in OMNeT + + shows better performance in network lifetime, throughput, residual energy, dropped packets, and delay.

Blockchain Based Delay and Energy Harvest Aware Healthcare Monitoring System in WBAN Environment

“…Data classification is significant to perform before data routing because successful data transmission shows high QoS performance. A priority-based MAC protocol is designed [ 31 ] to show better performance achievement for WBAN. A prior knowledge-based weighted routing algorithm is presented to choose the optimum route, and it is computed by residual energy, distance, delay and link stability.…”

“…Traditional QoS‐based protocols compute the priority level of different packets and measures the energy levels of each routing path for efficient QoS routing. Also, congestion aware mechanisms are employed to ensure minimizing high levels of congestion which has a high impact over QoS 38 Coherent and non‐coherent based: these kinds of protocols 7,39 save the node energy by saving the computations for processing the data.…”
