Dynamic-Adjusting AODV Routing Protocol Based on Max hop count

Nowadays, dynamically adjusting routing protocol parameters according to different and specific network scales is becoming a breakthrough of the Ad Hoc routing protocol research. In this paper, we propose a new AODV mechanism based on Max hop count, adding an intelligent and real-time estimation function to original AODV protocol to get the information of the max hop of the networks. The Dynamic-Adjusting AODV(DA-AODV) based on max hop count first calculates the value of max hop of the networks and then intelligently and dynamically adjusts its parameters based on the value of max hop to enhance the network performance. Finally, ns2 simulation results show that DA-AODV based on max hop count can significantly reduce the routing protocol overhead and enhance the networks throughput performance in networks of different scales.
