摘　　要：针对地理位置路由的路由空洞问题,提出基于时延要求的地理位置路由(DGGR)。DGGR路由旨在缓解路由空洞问题,同时满足数据包的时延要求。DGGR路由给遭受路由空洞的数据包定义扩展转发区。而扩展转发区的尺寸由数据包时延要求决定,使得数据包沿着扩展转发区传输数据包。仿真数据表明,相比于同类路由,DGGR路由在数据包传递率和负载均衡方面的性能得到有效地提高。To solve the problem of routing void in geographic routing,Delay-Guaranteed-Based Geographic Routing(DGGR)is proposed in this paper.The aim of DGGR is to address the routing holes and to ensure the delay of transmitting packet.For each packet that suffered from routing hole,we define an extended forward zone.And the area of extended forward zone depends on delay requirement.The packet is transmitted along extend forward zone.Simulation results show that our protocol outperforms the existing protocols in terms of several performance metrics,including packet delivery ratio and load balancing.
