Abstract

Most of MANET routing protocol simulations haven’t considered crossing effects of routing protocol and MAC protocol. In this paper, statistical method based on Multi-variance analysis is applied to evaluate the ad hoc network routing protocol performance results. Statistical results show that routing protocol and MAC protocol have different effect on different network metric, which will affect the overall network performance seriously. “Interactive effect” between routing layer and MAC layer will direct the protocol design in a “cross-layer” fashion instead of independent layered architecture. Mathematical performance evaluation model will be more effective and more accurate in performance comparison of newly built protocols than previous simple one without considering the “Crossing effect”. To make further analysis, we set up a simulation environment of “Vertical” traffic, and analyze the crossing effects between routing layer and MAC layer. In “Vertical” traffic pattern, MAC layer dominates delivery ratio metric, but if the multi-path mechanism is used to avoid congestion in MAC layer, the network system performance improves accordingly.
