Enhancing Security and Performance of Mobile Ad-Hoc Network (MANET) using Joint Authentication and Topology Control Scheme?

The progress to wireless network beginning with wired network has been a universal development model in the past years. The capability to move one place to another and adopt the infinite number of nodes brought by wireless network prepared it feasible in many applications. Between all the modern wireless networks, MANET is one of the main significant and unique applications. On the different to traditional network design, MANET does not engage a predetermined network framework; each single node works as uniformly a transmitter and a receiver. Nodes communicate straight with each other when they are both within the related communication range or else, they depend on their neighbors to broadcast the messages. The self-configuring capability of nodes in the MANET through it admired between important mission applications related to military utilize and emergency recovery. They are generally formed in the conditions of emergency and non-permanent operations or basically if there are no resources to set up involved networks. The results for traditional networks are usually not sufficient to offer efficient Ad-hoc operations. Both the infrastructure less network and disseminated nature lead the Mobile ad hoc network defenseless to malicious attackers. In this situation it is important to build up efficient intrusion detection processes to preserve MANET from attacks. Different level of security problems are raised by the wireless environment of communication and requirement of any security infrastructure. In this paper a Joint Authentication and Topology Control (JATC) scheme is proposed to adaptively tune the network configurations to optimize the effective throughput and the efficiency of authentication protocols for MANET. The main goal of selective encryption is to reduce the amount of data to encrypt while achieving a required level of security. Finally SNMP specifies a standardized way of exposing management data (system configuration, performance measurements, etc.) by way of defining a set of objects on the managed devices.
