【摘要】 目前提出的多种Adhoc组播路由协议都存在着各自的缺点:或有效性差,或控制开销大.根据区域路由原理,提出基于动态广播环的Adhoc网络组播路由协议(DBRMP).该协议为加入组播的组成员节点组织一个动态广播环,并使所有组成员的广播环组成的广播环图是一个连通图.由于两个组成员节点在其广播环相交时可通过相交节点建立路由,因此在连通广播环图中,任意两个组成员间可建立路由.文中利用NS2对协议进行了仿真,结果表明DBRMP协议具有较高的数据分组递交率、较小的维护路由开销和较好的可扩展性.更多还原

【Abstract】 A novel multicast routing protocol for Ad hoc networks, called dynamic broadcast ring based multicast routing protocol (DBRMP), is proposed, which is based on the principle of zone routing. In DBRMP, each member has a dynamic broadcast ring and the ring graph composed of all members’ broadcast rings is connected. In connected ring graph, because the route between two members can be established when their broadcast rings overlap, each member has one or more routes to other members. The protocol with NS2 is simulated and results show that DBRMP has a high data packet delivery ratio, low control overhead and good scalability.更多还原
