Security Problems in Heterogeneous Networks

Abstract — Security is a concern in the next generation Hybrid networks. This paper analyzes the various architectures that are proposed for next generation networks. Then we analyze their performance towards defending themselves from various malicious attacks and how the malicious nodes can exploit the differences in nature of the network to perform attacks. The solution to these attacks are provided by securing the network with a generic authentication mechanism that has a global vision, in avoiding the attacks that can bring down the entire network. The authentication mechanism follows a EAP based authenti-cation that will decide on the type on authentication mechanism that is followed inside a particular cell. The base stations connected to each other through the MSC will follow a unified authentication mechanism. The solution is then simulated in NS-2 and results are analyzed
