【摘要】 Ad Hoc网络是一个多跳的无基础设施网络,本文在分析Ad Hoc网络自身特点的基础上,引入了一种多组播业务并存的K重组播网络,这种网络相对传统的组播网络具有节省系统开销,降低能量消耗的优点.文中对K重组播网络中的节点连接度的不同变化情况进行了理论上的详细研究,并在此基础上设计了一种适用于K重组播网络的负载均衡路由算法.仿真结果表明该路由算法拥塞控制性能良好,并能显著提高组播业务的稳定性.本文提出的这种K重组播网络能够广泛的应用于许多实际通信场合.更多还原

【Abstract】 Ad hoc network is a provisional autonomous system of multi-hop mobile nodes.This kind of wireless network does not has infrastructure,so the method of composing ad hoc network is very flexible and convenient.In this paper,on the basis of analysis characteristic of Ad Hoc network,we have introduced a K fold multicast network.This K fold multicast network can run multiplicate of different multicast operations in one network topology.Although K-fold multicast network can be regarded as the combination of K entries of common multicast network,the system payload and energy cost of K-fold multicast network’s hardware design can be greatly reduced.This advantage is very available for Ad Hoc network.We researched different change instances of the node connection degree in this network situation in detail and designed a load balance algorithm.The simulation result indicated this algorithm can control the congestion well and increase the network stability.The simulation results also show that this algorithm is very suitable for this new kind of network which has high packet delivery ratio and routing establishment ratio.K-fold Ad hoc multicast network is a new kind of multicast network,it will be greatly applied in the military and medical conditions.更多还原
