Cooperative Communication for Multi-Hop Routing in ZigBee Network
Chang-Bin Ha, Hyoung‐Kyu Song · International Journal of Engineering Research and Applications · 2017
In this paper, we propose multi-hop routing scheme using RSSI to improve the reliability of ZigBee network.By using RSSI for the routing, the transmitted signal is less affected by the fading in each link on the routing path.If the proposed routing scheme is applied to relaying, the demodulation error is reduced in each relay node and the performance is significantly improved as the number of hops increases.Also, if the proposed scheme is applied to the cooperative communication, the improved diversity gain is additionally obtained.
