A novel multi-strategy cognitive routing

The cognitive routing can collect the network information, analyze the information and make the routing decision. A multi strategy cognitive routing will choose the routing strategy adaptively by different network environment. In this paper, a cognitive multi strategy routing with QoS constraint and load balance is proposed. If the payload of network is light, parameters of QoS performance, such as bandwidth and delay, should be emphasized to guarantee. The load balance would be taken more attention, while the payload is heavy. As the simulation results show, the proposed cognitive multi-strategy routing protocol offers a better performance of delay and throughput.
