Efficient scheduling of sporadic tasks for real-time wireless sensor networks

Industrial automation requires hard real-time delivery of data that can be of periodic or sporadic in nature. It is challenging to ensure hard real-time delivery of periodic and sporadic data to a multi-hop away destination in a bandwidth constrained environment, such as wireless sensor networks. In this regard, research has been done for joint scheduling […]

A cluster based routing approach in LTE ad-hoc networks

In this work, a new routing algorithm which allows smart terminals to join the ad-hoc network at random times in order to carry out data transmission using Long Term Evolution (LTE) infra-structure has been developed and simulated by using OPNET Modeler. The routing scheme has been realized by clustering the terminals according to some predefined physical layer […]

The Design of Safe Networked Supervisory Medical Systems Using Organ-Centric Hierarchical Control Architecture

There are growing demands to leverage network connectivity and interoperability of medical devices in order to improve patient safety and the effectiveness of medical services. However, if not properly designed, the integration of medical devices through networking could significantly increase the complexity of the system and make the system more vulnerable to potential errors, jeopardizing patient safety. The system […]

Exploring Stock Market Using Twitter Trust Network

As social networks are becoming more and more popular, more and more data are available from them. Researchers are now trying to extract useful information from these big data. One possible usage of social media is to investigate stock market. There are two major events to measure in stock market – price change and trade […]

Digging the innate reliability of wireless networked systems

Network reliability of wireless networks exhibits a prominent impact in successful advancement of the networking paradigm. A complete understanding of the network reliability demands its in-depth analysis, which is yet to be attempted in the literature. Therefore, we present a comprehensive study on the network reliability in this paper. Our step-by-step stochastic study, from node-level to […]

Elastic network functions: opportunities and challenges

Network function virtualization (NFV) and software defined networking (SDN) are key technology enablers for cost reductions and new business models in networking. The possibility to automatically and dynamically scale network services at run time is one of the main claims of NFV. Elastic NFV could be similar to what elastic cloud services provide for compute, with pay-per-use […]

Digital forensics in social networks and the cloud: Process, approaches, methods, tools, and challenges

As cloud computing and social networks become ubiquitous in our modern world, what come along with the nearly infinite storage and computing power are the security, privacy, and digital forensic challenges. Due to the completely different ways of data storage and processing in the cloud and social networks compared to their traditional counterparts, digital forensics practitioners are in need to […]

Design of energy efficient optical networks with software enabled integrated control plane

The growing energy consumption has posed new challenges for the future development of networks. Some earlier work has proposed solutions to improve energy consumption based on the existing control plane, for example, node/links sleeping. This study presents a new possibility to reduce network energy consumption by proposing a new integrated control plane structure utilising Software […]

Flow control enhancements in Content Centric Networking

In window-based flow control mechanism for Content Centric Networking (CCN), for one Interest (a content request packet), more than one Content Objects (content chunks) are expected to be received. TCP’s RTT estimation algorithm cannot be used directly for such scenarios because for some contents, there will be no Interest reference. In this paper, we extend TCP’s RTT estimation for […]
