sensor network, which consists of the convergence of sensor, micro-electro-mechanism system and network technologies, has a wide application prospect in national defense and environmental monitoring and so on . yet the sheer numbers of these sensors and the expected dynamics in these environments present unique challenges in the design of unattended autonomous sensor networks . therefore, self-adptive routing algorithm is studied in this paper 與傳統(tǒng)無線網(wǎng)絡(luò)相比,傳感器網(wǎng)絡(luò)節(jié)點分布稠密、易失效、節(jié)點資源有限、難以獲得全局信息,因此傳統(tǒng)的路由算法并不適合傳感器網(wǎng)絡(luò),必須針對傳感器網(wǎng)絡(luò)的特性研究新的路由機制與算法。
