| 摘 要： | 提出一种基于改进离散粒子群优化算法的DSR协议——P-DSR.引入智能代理作为粒子,将求解Ad hoc网络的最优路由问题等效为0-1组合优化问题,将链路稳定因子作为粒子群优化算法的适应值函数.仿真结果表明,与传统DSR协议相比,P-DSR协议具有较低的端到端时廷及较高的数据包投递率.

| Abstract: | Dynamic Source Routing(DSR) protocol based on improved discrete Particle Swarm Optimization(PSO) algorithm named P-DSR,is proposed.It introduces the conception of Intelligent Agent(IA),Ad hoc networks can solve the optimal routing problem using the 0-1 combinatorial optimization.It introduces the link stability factor as a PSO fitness function.Simulation results show that,compared to the original DSR protocol,P-DSR protocol can give lower end-to-end delay and higher packets delivery rate. |
