Wireless Sensor Network Routing Algorithm Based On Improved Ant Colony Algorithm

Wireless Sensor network (WSN) which is made by the convergence of sensor, nested computation, networks and wireless communication technologies, is a novel technology about acquiring and processing information. It is a late-model wireless networks of infrastructureless network and can be used for testing, sensing, collecting and processing information of monitored objects. WSN is a new research area of computer science and technology and has a wide application future,more and more attention. It will be much market in application of military, health, home, environment, etcIn this paper, at first, we gave a summary of characteristic and technical difficulties and challenges in the future of the wireless sensor network Protocol. Designing routing protocol of WSN is the main part of this dissertation. The author analyzed and compared some routing protocols that proposed by oversea researcher and assimilated excellence idea among them, Based on the ant's capability of finding the best paths between a food source and their nests,an improved ant colony system was put forward. Finally, there is the simulation of the routing protocol. Simulation results show that it can balance energy consumption between nodes,Then it can prolong the lifecycle of the whole network.In this paper we have six sections. In the first section, we introduced the background and current status of wireless sensor network protocol. The second section, we analyzed and compared some routing protocols that proposed by oversea research, we pointed out the defects of these protocols and our improvement direction. The third section, routing protocol based on improved ant colony system is introduced. The forth section, Our Simulation software are designed and developed. The fifth section, we give out the results of Simulation and analyzed our results. The last, some possible directions of further study are given.
