摘　　要：小卫星具有传播时延段,发射功率低等特点,多颗小卫星编队针对不同的任务需求灵活组网,可以承担单颗大卫星的功能。文章针对空间小卫星移动速度高,网络拓扑高动态变化的特点,设计一种弹性路由算法,保证网络的连通性,从而避免了小卫星的移动、节点被毁等原因造成的网络结构上的损伤,减少频繁发起路由寻找耗费的能量,提高路由的可用性以及小卫星编队网络的抗毁性和生存性。Many small satellites formation according to the different task requirements can assume the function of a single large satellite,due to their characteristics of short propagation delay,low transmit power and so on. This paper puts forward a resilient routing algorithm according to the characteristics of high movement speed and high dynamic variation of network topology of small satellites to ensure the network connectivity. And,this routing algorithm could avoid damages in the structure of network due to the movement and destroyed of small satellites. Moreover,it could reduce the consumption of energy caused by frequent route discovery,so as to improve the routing availability and survivability of the small satellite formation networks.
