RF4CE规范,2009年9月板,The ZigBee RF4CE specification is based on IEEE 802.15.4. MAC/PHY radio technology in the 2.4GHz unlicensed frequency band and enables worldwide operation, low power consumption and instantaneous response time. It allows omni-direct
Abstract—For the application of wireless sensor network technology in an energy self-sufficient condition monitoring appliance, we propose a new hybrid network topology to combine the advantages of the ZigBee standard with the need for lowest power
we propose a data fragmentation scheme to increase channel utilization and avoid inevitable collision. Our proposed scheme outperforms the standard IEEE 802.15.4 MAC in terms of collision probability and aggregate throughput. The proposed scheme is
