Abstract:
The advent of 5G networking technology has increased the expectations of mobile users for anywhere, anytime, content-rich experiences. On one hand, mobile devices such as smartphones and tablets are getting smaller and lighter, with the expectation that computationally intensive and sophisticated applications will be offloaded to a remote cloud. On the other hand, offloading applications will also produce an increase in the load on the wireless backhaul. Given the fact that mobile web traffic has increased significantly, computation offloading will add to the burden on the wireless networks. In this talk, we define the new concept of cognitive cloud offloader as offloading the computations scheduled based on characteristics of wireless networks. We introduce the concept of wireless-aware joint scheduling and computation offloading (JSCO) for multi-component applications, where an optimal decision is made on which components need to be offloaded as well as the scheduling order of these components. The JSCO approach allows for more degrees of freedom in the solution by moving away from a compiler predetermined scheduling order for the components towards a more wireless-aware scheduling order.
Meanwhile in the wireless networking world, the trend has shifted to multi-RAT enabled communications. We provide a comprehensive offloading solution that uses the multiple radio links available for associated data transfer, optimally. Finally in a more holistic approach, a time-adaptive and wireless-aware heuristic is proposed that will achieve two joint ends: (i) assigns the schedule order of applications components; and (ii) determines the offloading strategy while optimally the percentage of data to be sent by the mobile device and the cloud are allocated via each wireless interface.
