The challenges that face rural areas in S.A. include underutilisation and/or unsustainable use of natural resources; poor or lack of access to socio-economic infrastructure and services, public amenities and government services, lack of access to clean water or lack of water resources for both household and agricultural development; low literacy and skills levels. This paper reports on potential applications of internet of things (IoT) technologies that could contribute to sustainable rural livelihoods. These technologies have been categorised under land and water resource management, food security, rural infrastructure and services, agricultural logistics, disaster and risk management, public health and education and eco – management. The purpose of the paper is to prove the potential of IoT as a possible contributor to sustainable rural development.

A scheme of this type is usually known as, a smart card based password authentication. The core feature of such a scheme is to enforce two-factor authentication in the sense that, the client must have the smart card and know the card PIN number in order to gain access to the server. In this paper, we propose and advanced remote mutual authentication scheme between a smart card, a smart card reader and the backend server database to ensure system security integrity. Our scheme provides high security and mutual authentication at a reasonable computational cost. Furthermore, it restricts most of the current attack mechanisms. It is simple and can be adapted to any kind of lightweight devices. Description: 2nd International Conference on Cloud and Green Computing (CGC 2012), Xiangtan, Hunan, China, 1-3 November 2012.

This paper describes a project in which a physical model of a smart environment was created, connected to the Internet, and controlled by a rules engine. The physical model has facilities to sense various conditions such a temperature, light levels, whether windows and doors are open or closed, and whether or not there is an occupant in the room. This information is transmitted to a rules engine which would then decide on actions to take such as turning lights on or off, turning heaters on or off, and turning an air conditioner on and off. Through the creation of the physical model research questions were postulated and experiments conducted to determine if the Internet of Things can enable and facilitate the network requirements of a smart home. It is found that the Internet of Things as enabling technology can facilitate the creation of smart environments.

Climatologists and politicians often disagree over the interpretation of those facts arguing whether or not the increase of greenhouse gasses contribute to global warming or not. The public, in the meantime, often does not have access to the data in a form or via a channel which is easily understandable and accessible. This paper describes a project of timeously publishing hourly updates of the carbon levels at South Africa's Cape Point on Twitter and Facebook in a manner which is easy for the non-scientific public to interpret. This is an example of an Internet of Things application where physical devices take an active part on the Internet. As more and more physical objects are created with digital intelligence, the Internet of Things grows. This project demonstrates how physical devices can provide people with important information which may affect their health and well-being. The carbon related data is collected at Cape Point using Picarro monitoring equipment. The Picarro monitoring equipment makes multiple measurements per minute of various gases and stores them locally on the monitoring device. The carbon data is then forwarded hourly to the Beachcomber platform which is an Internet of Things platform designed to link things with people using standard Internet protocols. Beachcomber is a Java Enterprise Application running under Mobicents and supports a wide variety of protocols including HTTP, POP3 Email, XMPP, JMS, and a number of additional propriety protocols such as MXit. Beachcomber routes the incoming data to the appropriate Service Building Block which then processes the incoming data creating a number of graphs and visualisations of the data. A summary of the data, the graphs, and the visualisations are then forwarded to Twitter and Facebook in a timely manner for consumption by the general public. In the vision of the Internet of Things, this project is a stepping stone to future research in attempting to modify personal behaviour by providing timeous physical information. In the future, one can envision a smart city where, for example, the ticket prices for public transportation into the city centre are lowered automatically when the carbon levels are high thereby encouraging people to utilise the train or bus service. Alternatively, a future smart city could automatically increase the price of parking in the city centre when carbon levels are high thereby discouraging the use of private automobiles on such days. In addition, the smart city could then communicate with regular commuters encouraging them to telecommute on days when carbon levels are unacceptably high.
