AODV with intelligent priority flow scheme for multi-hop ad hoc networks

A mobile ad hoc network is formed by a cluster of mobile stations randomly located within a certain area without the infrastructure of base stations. There have been many researches proposing different models of routing protocols and numerous simulations to enhance their performances under varying conditions and constraints. However, most of them only focus on network layer without considering the influence of media access control (MAC) layer. In this paper, a new strategy of cross layer algorithm is proposed based on the characteristics of reactive routing and multi-hop jumping. In addition, artificial bee colony algorithm is performed to calculate the contention window of the nodes along the routing path over MAC layer. This framework could avoid data collision in MAC layer, and results in getting better performances of data transmission in network layer. Extensive simulations show that the proposed AODV with intelligent priority flow scheme is able to earn a significant improvement over the conventional routing algorithm.
