QoS Management in WSN-MCN Convergence Network Using Priority Based Traffic Models

Abstract

Technological advancements and increased developments leads to increase the development of hand-held devices which encourage the growth of Machine-to-Machine (M2M) communication. In this context devices belongs to heterogeneous network require a common platform to meet the challenges of data centric wireless services and applications. To satisfy the needs of M2M communication, Mobile Cellular Network (MCN) and Wireless Sensor Network (WSN) converged to a single platform. In this paper two priority models has been proposed with non preemptive priority and preemptive priority to analyze the data traffic at MAC layer of the converged network. The performance matrices are determined to maintain QoS in terms of reduced dropping and blocking probability, waiting time in the queue etc. Finally, the proposed models are compared in terms of QoS factors.

Improving network performance with an integrated priority queue and weighted fair queue scheduling

“…As showcased by Anita Swain and Arun Kumar Ray in [7], priority queue (PQ) scheduling is designed for key service applications for congestion management. In this model, the key services such as voice and video which are sensitive to delay and jitter are scheduled favorably to reduce the response delay when congestion occurs in the network.…”
