| Summary: | 碩士 === 國立臺灣科技大學 === 電子工程系 === 99 === In [14], a Ripple protocol was proposed to maximize the spatial reuse and protect nodes from unintentional packet collisions for a chain-based multihop wireless backhaul network (MWBN). A physical-carrier-sensing-based Ripple (PCS-Ripple) protocol is then presented to remove assumptions of ‘identical data transmission time’ and ‘identical interference range and transmission range’ in Ripple, and the shadowing effect was considered. An analytical model is further presented to estimate the performance of PCS-Ripple. The effectiveness of PCS-Ripple and the accuracy of the analysis were verified via NS-2. Simulation results indicate that PCS-Ripple achieved stable and higher throughput than that of 802.11 DCF in highly loaded situations.
