Research on pertinence of QoS Metrics Based on IEEE 802.15.4 in Wireless Sensor Networks

It is important for multi-constrained QoS MAC protocols to study the pertinences of QoS metrics. This paper investigates the pertinence of traffic load, average packet delay and delay jitter based on IEEE 802.15.4 with variable beacon order and superframe order in wireless sensor network by simulation and analysis. The relationship formulation of QoS metrics is proposed. Simulation is performed to validate correctness of these formulations, and shows that analytical results are consistent with simulation results.
