Wireless ad-hoc networks consist of a set of nodes which construct a random network topology by means of several communication media. Wireless ad-hoc network present a diversification in communication technology necessary to solve the end-to-end requirements of the QoS based communication networks. Of the numerous confronts in the composite dispersed system, the difficulty of secure routing based on a predefined position of inclinations, decisive to promising quality-of-service, is the focus of this research. Our previous work describes the process of providing the Energy Conserved Fault Tolerant Clusters QoS Routing service to the wireless ad-hoc networks (ECFCR) in the way of clustering the network based on energy consumption, fault tolerance rate, and mobility rate. A wireless ad-hoc network is efficiently clustered and cluster head is chosen based on the nodes which have higher energy, less mobility rate and high fault tolerance rate. Even though ECFCR provides an efficient clustering process, security in QoS routing does not achieve. To enhance the secure routing in wireless ad-hoc network, in this work, we are going to present a new approach which provides an authorized routing path from source to destination. Routing security is done using cache mechanism to evade misdirecting malicious node. Link failures are guarded against adversary or selfish nodes. For each node in the network, cache history is maintained which provides authenticated routing link for specific source destination pairs. Authorized nodes in the ad hoc network delineate the inappropriate routing directions. This cache mechnaims will improve the QoS routing path based on mobile node preferences and minimizes the communication overhead. An experimental evaluation is carried out to estimate the performance of the proposed Secured QoS Routing Path Discovery using Cache mechanism (SRPDC) in wireless ad-hoc networks in terms of routing overhead, routing efficiency, and energy consumption.
