Secure data forwarding in wireless ad hoc networks

Abstract

Network routing in wireless ad hoc networks is liable to attacks that may have a grave impact on network operations. Such attacks can be targeted at the route discovery process or the data packet forwarding process. Although the protection of route discovery is a critical prerequisite to ensure the robustness of the routing process, secured route discovery by no means eliminates attacks on routing. We, accordingly, propose a secure data forwarding protocol that detects faulty links in the packet forwarding process, which enables the corresponding sources to progressively route packets over non-faulty paths.

An Improved AODV Routing Security Algorithm Based on Blockchain in Ad Hoc Network

“…Once the trust value is set unreasonably, it will cause great misjudgment and form a false warning, thus affecting the performance of the entire network. In literature [12] In literature [13] Huang et al proposed to detect packet loss nodes based on one-way hash chain and one-time hash tag commitment. This detection method mainly relies on the form of forwarding redundant data packets and shared secret keys between nodes.…”
