摘要：Due to tremendous growth of the wireless based application services are increasing the demandfor wireless communication techniques that use bandwidth more effectively. Channel slot reutilizationin multi-radio wireless mesh networks is a very challenging problem. WMNs havebeen adopted as back haul to connect various networks such as Wi-Fi (802.11), WI-MAX(802.16e) etc. to the internet. The slot re-utilization technique proposed so far suffer due to highcollision due to improper channel slot usage approximation error. To overcome this here theauthor propose the cross layer optimization technique by designing a device classificationbased channel slot re-utilization routing strategy which considers the channel slot and nodeinformation from various layers and use some of these parameters to approximate the riskinvolve in channel slot re-utilization in order to improve the QoS of the network. The simulationand analytical results show the effectiveness of our proposed approach in term of channel slotre-utilization efficiency and thus helps in reducing latency for data transmission and reducechannel slot collision.
