Research On Routing Algorithm Of Wsn Based On Densely Deployed

In order to strengthen the entire network collected information on the robustness and accuracy in Sensor networks, nodes are often densely deployed. Nodes densely deployed on the one hand to improve the network collecting information on the validity and accuracy. On the other hand caused the signal interference and unnecessary energy consumption. In this paper, research is based on data redundancy DD routing protocols and routing protocols to avoid interference with.Wireless sensor network routing protocols study is an important element in wireless sensor field. Node density deployment, will cause a lot of data redundancy and excessive energy consumption. This paper study control parameters such as packet forwarding hops and forwarding probability on the basis of the Directed Diffusion routing protocol by setting the best jump the number of maximum hops, node-degree threshold, decreasing gradient to. Simulation shows that the improved routing protocol effectively reduces the node energy consumption, prevent network congestion.For the interference problems caused by nodes densely distributed. Use of simulated annealing principles, according to the characteristics of wireless sensor network designed a frequency allocation scheme for wireless sensor networks based on the SMACS/EAR. On this basis, according to the frequency spacing between nodes to control probability of data forwarding within a certain range, achieve effective control packet routing process which may encounter interference, energy consumption, and congestion problems.Finally, according to the algorithm theory, we use network simulator NS2 to compare the before and after improvement routing protocols in these aspects,such as energy consumption, the success rate of data transmission and so on,which verifys the validity of the algorithm.
