PREVENTION AND REACTION BASED SECURE ROUTING IN MANETS

[摘要] Mobile Ad hoc network can be set up anywhere, anytime without any predefined network infrastructure. Due to the infrastructure-less property, it becomes difficult to make use of the existing routing protocols for network services and it arises to a number of challenges in ensuring the security of the communication. Most of the ad hoc routing protocols that address security issues rely on trust relationships to route packets among participating nodes. These papers deal and analyze threats faced by ad hoc environments and provide corresponding security mechanisms. In this paper we present respective strengths and threats of the existing routing protocols and suggest an appropriate framework that can provide a trustful solution.
