Performance Analysis of Unsaturated Slotted IEEE 802.15.4 with Downlink and Uplink Traffic

摘要：

In this work, we analyze the performance of unsaturated slotted IEEE 802.15.4 with downlink and uplink traffic in the beacon enabled mode. We assume that the coordinator has Poisson flow to every node through indirect transmission and each node has Poisson flow to coordinator through direct transmission. Based on the assumption, we study the normalized throughput of the network with different Beacon Order (BO) and traffic load, and investigate how the factors affect the performance by comparing the simulation results between downlink and uplink traffic, where the Network Simulator (NS-2) is used.
