A Femtocell Cluster Based Cache Handover Strategy by Jihong Zhao, Xun Wang, Zhirong Luan

“…To improve the quality of indoor wireless communication,the femtocell begins to be deployed in different indoor wireless communication scenarios.In the densely deployed femtocell network,when users handover from the macrocell to the femtocell,the multiple RSRP from different femtocell seriously affect the accuracy of the handover process.To solve above problems,the idea of femtocell cluster was proposed to improve the handover accuracy and reduce the unnecessary handover.In addition,a cache handover strategy was proposed to improve the efficiency of handover from macrocell to femtocell.Simulation results verify the proposed algorithms and strategies.…”

Relay-based cooperative MAC protocol with rate adaptation by Fang-min LI, Tao ZHANG, Shuang-yin HU, Xin-hua LIU

“…The existing wireless cooperative MAC protocols rarely consider the impact of channel condition and node energy consumption.To this issue,a new wireless cooperative MAC protocol was proposed,which used the random linear network coding,and introduced a mechanism of request relay frame to solve the hidden terminal problem.Specifically,the proposed method adaptively adjusted the node rate according to RSSI,and determined the relay node based on the requirements of cooperative transmission.The simulation results show that the network performance can be improved through deploying the proposed protocol.…”

Analysis and improvement of route switch in IEEE 802.11s by Bo YOU, Yue-peng YAN

“…Analyzed the route switch of hybrid wireless mesh protocol(HWMP)in IEEE 802.11s and made an improve-ment to reduce the packet lost rate when routes switching was analyzed.Based on the received signal strength indica-tor(RSSI)a scheme with judgment threshold in mesh peer link management protocol was proposed,which controlled the status of peer link to change the timing of route switch.In this way,the packet lost was avoided.The experimental results show that the improvement reduces the packet lost rate by 2%~5% compared with traditional IEEE 802.11s in uncon-trolled wireless environment when nodes moving in low speed.…”
