PROJECT TITLE :

Coff: Contact-Duration-Aware Cellular Traffic Offloading Over Delay Tolerant Networks

ABSTRACT:

In recent times, the capacity of cellular networks has hardly kept pace with the dramatic explosion of cellular traffic from emerging mobile applications. To deal with this issue, a range of studies are proposed to offload the cellular traffic using delay-tolerant networks (DTNs) opportunistically shaped by mobile devices. These offloading schemes depend upon the idea of tiny-size content, that will be entirely transmitted over a single DTN contact. However, such an assumption, that was most likely valid in the past, can no longer hold with the increasing popularity of huge-size multimedia contents in the longer term. In this paper, we have a tendency to propose a novel contact-duration-aware offloading theme known as Coff, which consists of many styles that are specially tailored for DTNs. 1st, we use content fragmentation to utilize short contacts. Second, we tend to adopt network coding to achieve a near-optimum dissemination. Finally, we style a greedy load allocation (GLA) algorithm to realize a minimum of of the optimum. In depth simulations on both synthetic and real-world traces show that Coff is more efficient than the baselines, which extend from state-of-art DTN-based mostly offloading schemes with content fragmentation and network coding.
