Abstract

To connect the wired and wireless networks particularly the Mobile ad hoc Network is very interesting in real world situations due to its popularity and usefulness. Different mechanisms have been proposed to integrate MANETs and the Internet. These strategies differ in gateway discovery mechanism, cell switching criteria, ad hoc routing protocol. In our paper we remove the limitation from the above mentioned approaches and given a new approach in which cluster head and gateway will be same and that node is known as cluster head gateway (CHG) [1], in which all the responsibilities of cluster head and gateway will be perform by the CHG and we introduces the prediction table concepts and discusses a mechanism for selecting an alternate route in case if the CHG is unable to forward the packets to the destination, This approach providing Bi-directional connectivity between MANET and wired Nodes. By applying this approach we will reduce the overhead for deciding the cluster and gateway for an Ad hoc network and by maintaining the prediction table we can decide which node will work as CHG in future to make our communication unaffected. Finally, this paper conducts simulation experiments in the conditions where we connecting MANET nodes to the wired nodes using different networks.
基于簇头网关的移动自组网分层结构
连接有线和无线网络,特别是移动自组织网络,由于其普及和有用性,在现实世界的情况下非常有趣。已经提出了不同的机制来整合manet和互联网。这些策略在网关发现机制、单元交换标准、自组织路由协议等方面有所不同。在我们的论文,我们将限制从上述方法和给定的一种新方法,簇头和网关将相同的节点称为集群头网关(CHG)[1],在簇头和网关的所有责任将执行CHG和我们介绍了预测表的概念,并讨论的机制选择了另一条路,以防如果CHG无法数据包转发到目的地,这种方法在MANET和有线节点之间提供双向连接。通过应用这种方法,我们将减少为Ad hoc网络决定集群和网关的开销,并且通过维护预测表,我们可以决定将来哪个节点将作为CHG工作,以使我们的通信不受影响。最后,本文在使用不同网络将MANET节点连接到有线节点的情况下进行了仿真实验。
