Fine-Grained Reputation-based Routing in Wireless Ad Hoc Networks

摘要: Mobile ad-hoc networks (MANETs) are the best choice for instant when no fixed infrastructure is available. MANETs can support applications in a variety of areas like emergency assistance and inter-vehicle communications. Most developed wireless routing protocols designed to discover maintain an active path from source destination with assumption that every node friendly. However, it possible participating nodes may be selfish or malicious. A mechanism evaluate reputation trust each essential reliability protocol MANETs. We integrate management into Reputation based on constantly monitoring updating first-hand second-hand information. The within network able monitor their neighbors obtain information perceived behavior. Second-hand obtained sharing other nodes. thus create total value by combination firsthand then available neighboring decisions. Dirichlet distribution combined Bayes theorem provide finer granularity classification Fine-grained integrated explore possibility benefits improvement both route discovery maintenance
