Abstract
The characteristics of nodes moving arbitrarily and the network topology changing frequently lead to AODV routing protocol, which uses minimum hop-count as the metric for route selection, facing intermittent connectivity frequently which would cause QoS of network degradation in Ad Hoc Network. In this paper, we integrate three cross layer infor-mation which consists of the remaining energy of nodes, the remaining queue length and the hop-count from source node to destination node. Then we present the GRA-AODV routing protocol based on the gray relevance algorithm. By comparing the simulation and experimental results, in the case of slightly increase in routing overhead, the improved Gray Relevance Algorithm-AODV routing possesses lower average end to end delay and lower packet loss rate, and it has superior robustness in the mobile Ad Hoc Network with network topology changing frequently.

Summary
Ad Hoc network is a special network which used the exchanged information between nodes to achieve network communication. The feature of multi-hop nodes and intermediate nodes have the function of forwarding to reduce the transmission range of each terminal without reducing the scope of the network coverage, which would reduce the power consumption of the mobile terminal. It does benefit the health of users while providing the design basis for the miniaturization and low-power of mobile terminal. The Ad Hoc network has a wide range of applications, but due to the particularity of position change frequently of each node in the network, the network topology and the routing protocol change frequently. It is important to study routing protocol in the Ad Hoc network
