Stateless Multi Hop Optimization in Mobile Ad Hoc Networks

In the near future, computing environment can be expected based on the recent progresses and advances in computing and communication technologies. Next generation of mobile communications will include both prestigious infrastructure wireless networks and novel infrastructure less mobile ad hoc networks (MANETs). A MANET is a collection of wireless nodes that can dynamically form a network to exchange information without using any preexisting fixed network infrastructure. The routing protocols meant for wired networks cannot be used for mobile ad hoc networks because of the mobility of nodes. In this thesis, I propose a novel Optimization and Scalable Geographic Multi hop Protocol (OSGMH). Several virtual architectures are used in the protocol without need of maintaining state information for more robust and scalable membership management and packet forwarding in the presence of high network dynamics due to unstable wireless channels and node movements. Specifically, scalable and efficient group membership management is performed through a Virtual-zone-based structure and the location service for group members is integrated with the membership management. The research in developing general and systematic methods for intrusion detection and based on the classification elect the leaders in network for those are classified as high reliability. The stateless virtual tree-based structures significantly reduce the tree management overhead. Geographic forwarding is used to achieve further scalability and robustness. Mobility has a large impact on the behaviour of ad hoc networks. Multi hop is a fundamental service for supporting information exchanges and collaborative task execution among a group of users and enabling cluster-based computer system design in a distributed environment
