摘　　要：对定向扩散协议进行了改进,提出了GADD(GA based directed diffusion)协议.利用探测数据包策略进行初始路径集建立的方法,有效地避免了初期路由的盲目性;引入遗传协议对初始路径集进行优化,增强了路径的多样性、提高了节点能量的利用率,提升了路径集的整体质量.仿真表明,GADD协议不仅延长了网络寿命,减小了网络规模变化对路由协议性能的影响,缩短了无线传感器网络的数据传输延时,而且具有较好的收敛性.GADD （GA based directed diffusion） protocol was proposed based on the improvement of directed diffusion. In GADD, a detecting packet strategy was designed, by which the initial path series could be built free of blindness at premature stage. To optimize the path series, genetic algorithm was introduced to strengthen its diversity, promote its quality and improve the energy utilization rates of nodes. Simulation results showed that GADD not only prolonged the lifetime of wireless sensor network, decreased the impact of network size on performance, shortened the transmission delay, but also turned out to be of better convergence.
