ABSTRACT
As multimedia or visual WSN has contributed to new application areas, apart from power consumption, performance and QoS assurances, such as end to end delay, priorities differentiation are becoming crucial as opposed to the best-effort performance in traditional monitoring applications. Two-level Parallel Wireless Token Ring Protocol (TPWTRP) is introduced for priority-based delay sensitive collision-free channel access in WSNs, which uses parallel 1-limited and Exhaustive services to realize the priority-based scheme. A polling network model is proposed for mean queue length and information packet waiting time analysis. Theoretical and simulation results are identical and show that the new system efficiently differentiates priorities and meets the practical demands of priority based applications well.
