CRedit-based and reputation retrieval system

Abstract

The challenge of a mobile ad-hoc network (MANET) or hybrid wireless network (HWN) is that every node must rely on others to forward its messages, but selfish nodes might refuse to forward those messages or move to other subnetworks at any time, thus degrading network speed and retrieval efficiency. This paper presents a system called “cRedit-based and Reputation Retrieval system” that employs a distributed message transmission protocol to avoid censorship problems, forwarding and reliable routing algorithms to ensure reliable message routing, reputation and credit algorithms to encourage greater cooperation incentives, location and refresh algorithms to deal with nodes’ limited view even in high-churn network, and a protection algorithm to address the problem of selfish nodes. A series of experiments confirmed the system’s effectiveness in achieving superior network scalability, high retrieval rates, low transmission costs, and mobility resilience in hybrid wireless networks.
