SDVCA – A Robust and Secure Data Communication Protocol for Manet

Abstract

The existence of intruders is a threat factor in any network. Degradation of the network operation occur which include delay in transmission, reduced network energy level, low throughput and many. In heterogeneous networks, the threat is complex since it has several interconnected devices working with different operating systems. To solve the trust dispute in the network a Robust and Secure Data Communication Protocol for MANET termed as Software Defined networking enabled Virtual Certification Authority (SDVCA) is proposed. In MANET, the nodes forward information among them. To control the data flow in a MANET the network has to establish a controller node and forwarder nodes for transmitting or forwarding data. The forwarder node carries out the operation of router. The VCA provides authentication certificate for all the network nodes. Without this authentication, the node will be declared as an untrusted intruder. No data will be transferred to or through them. Hence a trusted network is formed and efficient safe data transfer is achieved. In the proposed scheme, the control logic of MANET is moved from forwarding plane (node) to control plane (node) for improving the network performance. A social network model in MANET is designed to create controller-based architecture. This controller node will function as a host and also as a pathway of connecting different social networks in MANET architecture. The results provide improved performances and the network has better throughput, and lesser end to end delay when compared with the existing techniques.
