Novel Radio Scheduling Framework for Optimal Energy Efficiency in Wireless Sensor Network

Wireless Sensor Network (WSN) has been penetrating deeper into various commercial monitoring services/application which demands substantial amount of residual energy to assure superior network lifetime. In this perspective, there are various Medium Access Control (MAC) as well as Carrier Sense Multiple Access (CSMA) scheme which is frequently adopted to address this problem; however, they too have shortcomings. Hence, this paper introduces a novel computational model of radio scheduling where a network model and neighborhood exploration are carried out using graph-based method. Further, the scheme introduces a novel management of routing to effectively control timeslots and message. Further, a simplified packet prioritization scheme is implemented balancing the demands of normal and urgent services. The simulation outcome shows that proposed scheme excels better data transmission performance in contrast to existing MAC and CSMA-based schemes.
