Kavya A.P., D.J. Ravi . A Context-Adaptive Hybrid MAC Scheme for Provisioning QoS and Energy Savings in Delay Sensitive Wireless Sensor Network Application. International Journal of Computer Applications. 184, 49 ( Mar 2023), 40-45. DOI=10.5120/ijca2023922614
An effective WSN communication protocol can help IoT applications to offer faster services in an efficient way. In order to reduce the energy consumptions various MAC protocols are introduced by the researchers based on duty cycle mechanism. However, none of the existing MAC protocols have been able to successfully balance the need for high power efficiency, low latency, and excellent QoS. A context-adaptive hybrid MAC (CA-HMAC) protocol is proposed in this paper for providing a higher degree of energy conservation under low traffic loads, and better transmission rates under high traffic loads. It presents hybrid scheduling algorithm to handle packet collisions, control idle listening, and conserve energy. The proposed protocol also focuses on adjusting power for packet transmission and data prioritization, followed by delay-aware routing mechanism. The design of the proposed MAC protocol is carried out in such a way that its response is faster towards executing its operation associated with duty cycle and packet transmission. The design and development of the proposed scheme is carried out on MATLAB tool. The experimental results show, that the proposed MAC protocol outperforms similar existing techniques in terms of throughput, remaining energy, and reduced packet delay.
