Mobile broadband traffic has been increasing in the last years. To cope with such traffic demand, heterogeneous networks are an effective solution characterized by deploying networks with different cell sizes, radio access technologies (RATs) and carrier frequencies. Since the coverage area of these networks (or layers) is partially overlapped, users can be steered to a specific layer in order ...

Workstation clusters have high performance interconnects with programmable network processors, which facilitate interesting opportunities to offload certain application specific computation on them and hence enhance the performance of the parallel application. Our earlier work in this direction achieves enhanced performance and balanced utilization of resources by exploiting the programmable fe...

A Heterogeneous Network (HetNet) comprises of multiple Radio Access Technologies (RATs) allowing a user to associate with a specific RAT and steer to other RATs in a seamless manner. To cope up with the unprecedented growth of data traffic, mobile data can be offloaded to Wireless Fidelity (WiFi) in a Long Term Evolution (LTE) based HetNet. In this paper, an optimal RAT selection problem is con...

Opportunistic networking (a.k.a. device-to-device communication) is considered a feasible means for offloading mobile data traffic. Since mobile nodes are battery-powered, opportunistic networks must be expected to satisfy the user demand without greatly affecting battery lifetime. To address this requirement, this work introduces progressive selfishness, an adaptive and scalable energy-aware a...

This work addresses the problem of enabling resource-constrained sensor nodes to perform visual analysis tasks. The focus is on visual analysis tasks that require the extraction of local visual features, which form a succinct and distinctive representation of the visual content of still images or videos. The extracted features are then matched against a feature data set to support applications ...

The exponential growth of video data in networks has led to flow occupying a significant proportion network traffic, causing congestion and poor service quality. To address this issue, it is crucial quickly offload ensure high-quality for users, especially the context cloud-edge collaboration. We propose strategy collaborative offloading between cloud edge computing, analogous water (WFO). When...

Energy and time effectiveness is a primary consideration for smartphones or mobile devices. Cloud computing has the ability to conserve mobile device’s energy by using the concept of computation offloading. Existing studies focus on offloading computation by assuming the relations among the factors like wireless bandwidth, the amount of computation to be performed, and the amount of data to be ...

Mobile Cloud Computing is an emerging technology that integrates the cloud computing concept into the mobile environment. The limitations of mobile devices such as its storage capacity, battery lifetime can be overcome with the offloading of applications that is migration of large or complex computation to servers or cloud. This paper presents the adaptive offloading of the tasks using the opti...
