無線傳感器網(wǎng)絡基站位置優(yōu)化算法研究
[Abstract]:Wireless sensor network (WSN) is a self-organized distributed network composed of a large number of wireless sensor nodes, which has been widely used in various fields. Its main feature is that the resource is strictly limited, especially the energy limitation, which directly affects the lifetime of the whole network. In order to make the network can work for a long time, energy-saving is particularly important. In this paper, the methods of prolonging the lifetime of wireless sensor networks are studied from the point of view of base station location optimization. The main work is as follows: (1) introduce the development prospects of wireless sensor networks, the current research situation and the technologies related to the lifetime of wireless sensor networks. Including the definition of the lifetime of wireless sensor networks, coverage control, routing protocols, base station location optimization technology. (2) the use of optimization theory to model the system model of wireless sensor networks, This paper analyzes the method of optimizing the lifetime of wireless sensor networks, and aiming at the disadvantage of Greedy algorithm which can not balance the energy distribution of wireless sensor networks, by introducing the concept of potential value, puts forward an optimization algorithm of base station location based on energy perception in wireless sensor networks. Simulation results show that the new algorithm can balance the network energy distribution well and further prolong the lifetime of wireless sensor networks. (3) A base station mobility algorithm based on genetic algorithm is proposed. Firstly, the optimal base station location of wireless sensor networks is modeled with the concept of potential. Secondly, the standard genetic algorithm is used to solve this model, aiming at the problem of "precocity" of standard genetic algorithm. The hierarchical genetic algorithm is used to solve the mathematical model again. The result of the genetic algorithm is the optimal position of the base station in the next round of data collection. The simulation results show that the genetic algorithm can solve the mobile path of the base station quickly, and the survival time of the wireless sensor network can be further extended by using the base station mobility algorithm.
