Research On WSN Routing Protocol Based On SCA Algorithm

The WSN routing algorithm has become a hot point at present. The deference between modern and traditional routing algorithm is that because of the simpleness of node and the limitation of power, when we design the routing algorithm, we should consider carefully the energy consumption,computing capacity and storage resources. Ant colony algorithm that simulates ant collective routing behavior in nature is a based on population heuristic biomimetic stochastic optimized algorithm. Since it was brought up by Italian scholar Dorigo M in 1992, it has been improved and used in many areas.First this article introduces the basic knowledge and routing protocol of WSN and the basic principle of ant colony algorithm, and then introduces SCA (Sensational and Consciousness Algorithm) in article [20] that has been modified and can be used in routing protocol. I have added an Energy-aware function in this algorithm and modify pheromone Adaptive update function. At last we put the modified SCA algorithm into use in WSN routing protocol, and we got a kind of smart and reliable routing protocol. The main idea of this article is to save the energy of any point and balance the energy of the whole net. This protocol has solved the contradictions between precocity and stagnation and use the data segmentation strategy, greatly enhanced the efficiency of the entire network routing. The last part of the article reached through the simulation of experimental data, as well as the relevance of the effectiveness of protocol, and compared with the RPBAA protocol of article [21], verified the protocol in the efficiency and superiority.
