摘要
LEO卫星网络切换协议中的路由选择策略应当综合考虑路由本身优化性,路由计算复杂性,路由更新的信令代价。提出适合LEO网络卫星切换要求的动态混合路由选择策略(DHRS:DynamicHybridRouteSelection),即发生卫星切换时,由卫星节点根据移动终端用户切换前所处位置和切换前路由表等信息,为移动终端选择合适的路由。
The performance of satellite handoff protocol is depended on the optimality of the selected route, complexity of route computing and the cost for route updating. According to the requirement of satellite handoff, in this paper we proposed DHRS(Dynamic Hybrid Route Selection).The strategy use the information about user location and the route to decide the optimal handoff for the end users.
