Performance of random network coding for data dissemination
Network coding is an alternative to traditional store-and-forward routing and is known to be necessary to achieve network capacity. It has also been shown randomized network coding is robust, and far outperforms store-and-forward for multicast. While much focus has been on the data rates achievable …

Service Order Handling
Current service order handling systems in telecommunications industry have problems such as user-unfriendliness, long service waiting time, uneasy customization of services, limited capability of in-house services, and inefficient human resources allocation. Consequently, the current solutions for …

An analysis of low-earth-orbit-satellite communication systems
… system, low-earth-orbit satellites, can provide store-and-forward, as opposed to real time, communication for many earth stations. The advantages and disadvantages of such a system is presented. Material covering protocols and communications architectures is elaborated upon for the use of amateur …

Gesture based interface for asynchronous video communication for deaf people in South Africa
… The gesture interface was implemented on a store and forward video architecture since this preserves the video quality even when there is low bandwidth.

Developing locally relevant applications for rural South Africa : a telemedicine example
… there is a digital divide between rural and urban areas. In order to overcome this division, we need to provide locally relevant Information and Communication Technology (ICT) services to these areas. Traditional software development methodologies are not suitable for developing software …

Transferring big data across the globe
… data via the Internet is a routine and common task for users today. The amount of data being transmitted by the average user has dramatically increased over the past few years. Transferring a gigabyte of data in an entire day was normal, however users are now transmitting multiple …

On a wildlife tracking and telemetry system : a wireless network approach
… is proposed, with lightweight VHF-like tags and high performance GPS enabled tags, bound by a common wireless network design. Tags transfer information amongst one another in a multi-hop store-and-forward fashion, and can also monitor the presence of one another, enabling social behaviour …

Networking from a network coding perspective
… network operation beyond traditional routing, or store-and-forward, approaches, allowing for mathematical operations across data streams within a network. This thesis considers a number of theoretical and practical networking issues from network coding perspectives. We describe a new distributed …

Application and Evaluation of Teledermatology In An Underserved Area of Honduras
… offers great potential in improving the standard of dermatologic care by bridging the gap between the expert opinion of dermatologists and those without access to basic dermatologic care, particularly in developing nations, where skin disease continues to be a major public health problem. …

CubeSat Constellation Analysis for Data Relaying
… technology limits the amount of time, and number of accesses with ground stations. It has been proposed to use a constellation of CubeSats to improve relay performance and increase the number of accesses between a CubeSat and ground stations. By using the spatial and temporal analysis …

Social-based trustworthy data forwarding in vehicular delay tolerant networks
… of research attention from academic community and indus-try. For many applications in VANETs, information has to be transmitted through mul-tiple hops before it reaches its destination that makes it a subject to various security at-tacks and privacy breaches. Thus, security and privacy issues …

Applying Multi-Packet Reception with DTN in Vehicular Ad-hoc Networks
… (DTN) in which nodes are partially connected and existing path may not available between partial nodes due to limited distance for wireless transmissions. To achieve successful packets delivery in DTN, routing protocols have been proposed by using the mechanism of store and forward as well as …
