Research On Routing Technology For QoS Based On Bee Colony Algorithm In Wireless Sensor Networks

Wireless sensor network is widely concerned with Internet technology, wireless communication technology and micro-electromechanical (the Micro-Electro-Mechanism System, MEMS) rapidly developing. It is considered one of the important technology to make far-reaching implications to human lifestyle. Because of the advantages of wireless sensor network with its self-organization, miniature, low cost, flexibility, wireless sensor network can be widely used in military, environmental monitoring and forecasting, health care, smart home, building state monitoring complex machinery monitoring, urban transport, space the field of exploration, storage management, as well as airports, large industrial park security monitoring and so on. With in-depth research and extensive application and extensive application of wireless sensor network, wireless sensor network will be gradually deep into the various areas of human life.Routing protocol is a research priority for wireless sensor network, wireless sensor network routing protocols to provide quality of service guaranteed to more great design challenges. This article describes the differences of the quality of service between wireless sensor network and tradition nework, and introduces some QoS routing protocol at this time and do some summary.Then we analyze the principle and characteristics of the bee colony algorithm, learn its advanced algoritmm idea. Lastly we supply a QoS algorithm for wireless sensor network based on bee colony algorithm.Bee colony algorithm has some of the features, such as Self-organized, distributed parallel computing, robustness, particularly suitable for wireless sensor network. This paper uses bandwidth, delay, delay jitter as quality of service parameters, and the QoS routing algorithm based on bee colony for wireless sensor networks is designed. However, due to the bee colony algorithm is easy to fall into local optimal solution, The algorithm introduces a tabu search ideas.And also because of the energy is limited in wirelss sensor network, the algorithm introduces a way of ensuring the energy equilibrium path of the routing mechanism to extend the life cycle of the network and keep the energy balanced. The algorithm utilizes different roles to affect the bee’s transition probability, to guide the bee to the right direction, and sets expend of delay and delay jitter as the path costExperimental results showed that the algorithm is effective, real-time and energy balance algorithm, can provide better performance on stability. After the QoS routing algorithm, which based on ant colony optimization, were applied to Directed Diffusion, the data transmission has improved on real-time side. Furthermore, by adjusting the ratio of the path cost and the energy, the algorithm can optimize quality of the routing, and meet different application requirements.
