Real-time reliable clustering and secure transmission scheme for QoS development in MANET

The Quality of Service (QoS) of the Mobile Adhoc Network (MANET) is dependent on various factors like clustering nodes, route selection, and how data transmission is performed. Towards this, there exist numerous techniques in clustering the mobile nodes and securely performing data transmission. Still, the methods struggle to achieve expected QoS performance. When it comes to data communication, MANETs often struggle to provide better QoS while still meeting security requirements. The MANET is vulnerable to different kinds of attacks because it lacks a reliable authority. To overcome this issue, an efficient Real-time Reliable Clustering and Secure Transmission (RRCST) approach is presented in this paper. The method starts with clustering the nodes in a region where the selection of cluster head is performed according to the previous transmission behavior and node statistics. The nodes are clustered based on their geographic features, and the cluster head is chosen from each cluster based on various support measures computed over energy, transmission, and geographic features. In addition, the routing is implemented using a novel method that selects the route based on the reliable transmission support (RTS) value calculated for different routes. In addition, the method selects a route based on various QoS support values computed for each route. The proposed RRCST technique offers a clustering accuracy of 97% for 200 nodes. The proposed method improves the performance in data security and QoS parameters.
