A Content-Based Routing Scheme for Mobile Data Offloading in Pocket Switched Networks

摘要

Existing cellular network infrastructure will likely be compromised in the future by the increase of mobile users and mobile data services. Continuous improvements of network infrastructure and several mobile data offloading strategies are promising solutions for cellular providers to cope with the demand increase of mobile data. However, these options require a lot of cost and time to implement. Few studies have been conducted to assess whether Pocket Switched Network (PSN) can be applied to support mobile data offloading. In this paper, we present a PSN mobile data offloading scheme that utilizes mobile users with available connectivity to deliver content-aware data to other mobile users. This paper also aims to evaluate whether PSN routing schemes can be applied to improve the current strategies in mobile data offloading. The simulation study exhibits promising results in terms of message delivery and latency reduction.
