Development of mechanisms for MAC channel selection to improve the performance of IEEE 802.15.4 beacon-enabled network

An improved mechanism called Scan First 3 Channels (SF3C) is developed to reduce the communicating frequency among devices and PAN Coordinator. The throughput and energy consumption are major performance indexes for it. Meanwhile, the beacon-enabled mode for broadcast transmissions in WPAN has higher flexibility than the non-beacon -enabled mode. In the research, a new analytic mode of the IEEE 802.15.4 beacon-enabled mode is developed to improve throughput. Furthermore, the MAC performance in the simple star topology is evaluated.
