Exploiting Parallel Networks Using Dynamic Channel Scheduling

Abstract

Many researchers have been focusing on the outcomes and consequences of the rapid increase and proliferation of mobile wireless technologies. If it is not already the case, it will soon be rare for a user to be in a situation where absolutely no network connection exists. In fact, through numerous devices, users will soon expect to be connected in all places at all times. Through the great variety and increase in the capabilities of these devices, it is not a surprise to find a single user with many connection opportunities. As a result, we believe that the next major evolution of wireless mobile networks will be in the exploitation of multiple network connections in parallel. Due to network heterogeneity, the major challenge in such situations is to determine the way that these networks can be utilized to better serve different network applications. In this work, we propose a dynamic channel scheduling mechanism that adapts to the state of the available channels to provide more efficient usage of network connectivity. We do so by observing channel throughput, creating a set of channel usage combinations, and then choosing the most efficient combination. We evaluate an implementation of the proposed mechanism using emulation. Our results show that under realistic conditions our dynamic approach greatly improves cost delay metrics, and the overall user-perceived performance compared to a more static approach.

Optimizing Mobile Application Communication for Challenged Network Environments

“…However, the platform is unaware of what policies, financial restrictions, and other data priorities a user or organization may want applied. There are numerous works related to a platformonly communication management scheme as multiple communication channels can be dynamically allocated based on availability or bonded to create compound channels with greater throughput capacity [14,30]. While Submit dynamically schedules traffic based on channel availability, it does so without modifying the underlying platform to combine or bond channels.…”
