摘要 MANET(Mobile Ad Hoc Networks )的特点是所有节点之间均采用无线通信,没有基站参与通信,节点可以随意移动,因此好的路由协议是MANET的关键.本文提出TDSR协议,利用已有的信息,在节点间形成一条尽可能窄的隧道,缩小了搜索的范围,减少了路由的时间.搜索的过程采取两种格式的路由寻找包,节省了网络的资源.通过实验模拟和比较,TDSR的各项性能均优于同类型的路由协议. Mobile Ad Hoc Networks are characterized by multi-hop wireless connection, absence of any infrastructure, and frequent host mobility. Design of efficient routing protocols in such networks is a challenging issue. TDSR protocol proposed in this article uses information stored in mobile host to form a tunnel. In additional, searching a route is limited in the tunnel thus to reduce searching area and time. Two types of RREQ are used in TDSR. In simulation, TDSR performs better than other routing protocols.
