Cross-layer Routing Protocol for Ad Hoc Networks Based on Synthetical Metric
XU Zong-ze · Jisuanji gongcheng · 2010
Traditional Ad Hoc network routing protocols are mainly based on the condition called shortest path,it can not support multi-rate mechanism well and usually lead to local congestion.This paper proposes a Synthetical Metric Routing Protocol(SMRP) with cross-layer design.It takes rate on physical layer,competition on MAC layer and queue length on network layer into account.This method can utilize multi-rate support better and avoid local congestion.Simulation results show that SMRP performs better than traditional routing protocols including network throughput and delay.
