Cellular networks are currently facing severe traffic overload problems caused by excessive traffic demands. Offloading part of the cellular traffic through other forms of networks, such as Delay Tolerant Networks (DTNs) and WiFi hotspot, is a promising solution since these networks can only provide intermittent connectivity to mobile users, utilizing them for cellular traffic offloading may re...

Data traffic over cellular networks is exhibiting an ongoing exponential growth, increasing by an order of magnitude every year and has already surpassed voice traffic. This increase in data traffic demand has led to a need for solutions to enhance capacity provision, whereby traffic offloading to Wi-Fi is one means that can enhance realised capacity. Though offloading to Wi-Fi networks has mat...

A promising way to use limited 3G mobile resources efficiently is 3G mobile traffic offloading through WiFi by the user side. However, we currently do not know enough about how effective the mobile traffic offloading is in the wild. In this paper, we report the results of a two-day-long user-based measurement of mobile traffic offloading by over 400 android smartphone users in Japan. We first e...

The exponential increase in mobile IP data usage causes a shortage in the mobile bandwidth. Traffic offloading is regarded as a solution to the exploding growth of mobile broadband data traffic in the mobile networks. In this paper, a content aware traffic offload scheme is proposed to implement using multiple access paths simultaneously. Moreover, the process flow based-on the scheme in Long T...

In this paper, we propose Cost-Effective Multi-Mode Offloading (CEMMO) that enhanc...

Owing to the increasing number of vehicles in vehicular cyber-physical systems (VCPSs) and the growing popularity of various services or applications for vehicles, cellular networks are being severely overloaded. Offloading mobile data traffic through Wi-Fi or a vehicular ad hoc network (VANET) is a promising solution for partially solving this problem because it involves almost no monetary cos...

The wide-spread proliferation of smartphone-like devices has caused a tremendous increase in mobile data usage unmatched by the slower increasing available bandwidth. Consequently, this has caused severe traffic overloading in cellular networks. An immediate available remedy for this problem is offloading the traffic through WiFi access points. In this paper, we study the deployment and recruit...

Growing traffic volumes and the increasing complexity of attacks pose a constant scaling challenge for network intrusion prevention systems (NIPS). In this respect, offloading NIPS processing to compute clusters offers an immediately deployable alternative to expensive hardware upgrades. In practice, however, NIPS offloading is challenging on three fronts in contrast to passive network security...

• FIB aggregation • Reduce the size of the Forwarding Information Base (FIB) • Remove redundancy while ensuring forwarding consistency with the original FIB • Traffic offloading • Glue together a hardware-centric forwarding fabric (fast-path) with a softwarecentric route controller (slow-path) • Offload the top-volume FIB entries to the fast-path, handle the remainder at the slow-path • Leverag...

LTE femtocells have been commonly deployed by network operators to increase network capacity and offload mobile data traffic from macrocells. A User Equipment (UE) camped on femtocells has the benefits of higher transmission rate and longer battery life due to its proximity to the base stations. However, various user mobility behaviors may incur network signaling overhead and degrade femtocell ...
