The Cognitive Ad-hoc Network Spectrum - Routing Selection Method

Based on cognitive self-organizing network transmission delay larger and larger interference to primary user receiver problem, put forward a method of spectrum joint routing selection, this method is effective to consider the transmission delay and the main user interference at the receiving end, mainly from < 1 > bandwidth available probability; < 2 > sent via link the number of bits of variance; < 3 > spread spectrum characteristic; < 4 > primary user receiver protection; < 5 > spectrum sensing five aspects to consider. Cognitive users of the information interaction with on-demand routing discovery process started, and to establish collaborative perception nodes along the route cluster, using the routing maintenance message to maintain the nodes in the cluster. At the same time on the cognitive network capacity maximization as the goal, put forward to jointly design spectrum collaborative perception and channel allocation. The simulation results prove the effectiveness of the method.
