Cross Layer Based Temporally Ordered Routing Protocol for Wireless Mesh Networks.

Abstract

Abstract—In this paper a proactive protocol Cross Layer Based Temporally Ordered Routing Protocol (CL-TORA) is developed to measure the performance of the Wireless Mesh Networks by using a newly adopted routing metric NCLRM. CL-TORA considers four link quality impact factors in estimating the route selection through the cross layer strategy. The conventional layered-protocol architecture does not provide optimal performance for wireless mesh networks (WMNs). The method of optimization decomposition of the protocol stack can achieve optimal network performance. This method usually results in a clean-slate protocol architecture that is different from the protocol architecture of WMNs. The bandwidth available in the node, load on the node, delivery rate of the link and interference on the link factors are considered for cross layer design. By making use of these link factors the effect of route selection is greatly optimized. The developed CL-TORA protocol not only improve the network throughput to a greater extent it also reduces the end to end delay while achieving the load balance route results.
