OSO: Mitigating data flooding attack in Wi-Fi offloading

In such an era that mobile devices produce ever-increasing amounts of data, Wi-Fi offloading enables mobile users to upload delay-tolerant data over Wi-Fi, which speeds up the upload but comes at constrained mobility and security threats. In this paper, we analyze the threats of data flooding attack in Wi-Fi offloading and propose an improved Wi-Fi offloading architecture to mitigate the impacts of such attack. Different from existing systems which store and forward data to the server, our architecture deploys control server in residential area network for the load balancing of offloading devices. Two experiments illustrate that our work can effectively improve the throughput and reduce the data delay under data flooding attack, compared with the generic architecture in a store-and-forward fashion.
