分层网络中CHG方法与MANET性能比较的仿真研究
Simulation Study For Performance Comparison in Hierarchical Network With CHG Approach in MANET
摘要：
将移动自组网用于商业目的并不是一件容易的事情。与蜂窝网络等其他无线技术不同，移动自组网面临着管理功能、路由选择和可扩展性等方面的难题。为了解决这些复杂性，提出了MANET的分簇方案，以便以分层的方式组织网络拓扑结构。已经开发了许多聚类技术。聚类是一种将节点聚合成组的方法。这些组包含在网络中，它们被称为集群。通过增加网络容量和减少路由开销，通过集群带来了更高的效率和有效性的可扩展性有关的节点数量和高移动性的必要性。集群中的管理器节点负责许多功能，例如集群维护、路由表更新和网络中新路由的发现。称为网关节点的另一个节点与另一个集群通信。在本文中，我们去掉了簇头（CH），提出了一种新的方法，将簇头和网关等同起来，这个节点称为簇头网关（CHG），簇头和网关的所有职责都由簇头网关（CHG）自己来完成。通过Exata仿真，在保证吞吐量不变的情况下，该方法降低了网络开销，提高了网络的整体性能。
英文摘要：
The implementation of MANET for commercial purposes is not an easy task. Unlike other wireless technologies such as cellular networks, MANET face more difficult problems concerning management functions, routing and scalability . As a solution to these complications, clustering schemes are proposed for MANET in order to organize the network topology in a hierarchical manner. Many clustering techniques have been developed. Clustering is a method which aggregates nodes into groups. These groups are contained by the network and they are known as clusters. By Increasing network capacity and reducing the routing overhead through clustering brings more efficiency and effectiveness to scalability in relation to node numbers and the necessity for high mobility. The manager node in clustering has responsibility for many functions such as cluster maintenance, routing table updates, and the discovery of new routes within the network. The other node named as gateway node communicate to the other cluster. In this paper we remove the cluster head (CH) and given a new approach in which cluster head and gateway will be same and that node is known as cluster head gateway (CHG), in which all the responsibilities of cluster head and gateway will be perform by the Cluster head gateway(CHG) itself. By applying this approach we reduce of overheads and improve the over all performance of the network while throughput will be same in both condition with the help of Exata simulation.
