A Security Scheme for Cluster Based Mobile Ad Hoc Networks

One of the main characteristics of Mobile Ad-hoc NETworks (MANETs) is high mobility and unpredictable movement nodes. Some times one or more nodes enter to or exit from the network in an instance. In some other cases one or more nodes move from its own place to another place. Everything is influenced by these moving natures in the network which consequently causes some problems for the management of the networks. On the other hand we can assume that there are many malicious users may attack the network via eavesdropping network traffic and change information in the network or create more traffic and increase energy consumption. Anyway this is a serious problem in the network and providing a secure MANET has high priority in the networks management. However, the unique features of Cluster Based MANETs, in one hand, and employing the cross layering technique on the other hand, are the main factors of our success in achieving a secure service discovery in MANETs. In this paper we compare all type of management information in MANETs and also introduce a new mechanism to secure network (Data and Communication). We show how cluster based networks integrates routing and security to achieve a secure and trusted way of deploying services in MANETS.
