A Hybrid Routing Protocol for Unobservable Security in Mobile Ad-hoc Networks
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2014, Vol 3, Issue 4
Abstract
Security of mobile ad hoc network is crucial due to infra structure less network and mobility of wireless media. In this paper, we propose an Hybrid Routing Protocol for Unobservable Secured (HRPUS) to offer privacy preservation to all types of packets. HRPUS works with USOR (Unobservable Secure on-demand Routing protocol)to protect against blockhole attack. In ad hoc network, when a source searches for a route to a destination using HRPUS protocol, an intermediate node can reply with its cached entry. To strengthen correctness of such routing discovery process, we propose a method in which the intermediate node requests its next hop to send a confirmation message to the source. After receiving both route reply and confirmation message, the source determines the validity of path according to its policy. As a result, this strategy discourages malicious nodes from intercepting packets. Simulation results show remarkable improvement in throughput with moderate increase of control messages.
