(University of Pretoria, 2011-10-12)Many wireless sensor network (WSN) applications depend on knowing the position of nodes within the network if they are to function efficiently. Location information is used, for example, in item tracking, routing protocols ...
-
(University of Pretoria, 2018)The advent of IoT as the next dominant player in cyber circles has ignited much research interest and a closer synergy between communication and computing models. Software-defined networking (SDN) and wireless sensor ...
-
(University of Pretoria, 2011-07-14)This dissertation presents the findings of a generic model aimed at providing secure communication with remote computers via the Internet, based on smart cards. The results and findings are analysed and presented in great ...
-
(University of Pretoria, 2017)Cyber security is a major concern due to global incidents of intrusion. The impact of the attacks on the electricity grid can be significant, resulting in the collapsing of the national economy. Electricity network is ...
-
(University of Pretoria, 2011)Wireless Sensor Networks are the main representative of pervasive computing in large-scale physical environments. These networks consist of a large number of small, wireless devices embedded in the physical world to be ...
-
(University of Pretoria, 2009-06-29)Recent development has lead to the emergence of distributed Wireless Sensor and Actor Networks (WSAN), which are capable of observing the physical environment, processing the data, making decisions based on the observations ...
-
(University of Pretoria, 2015)Wireless sensor networks have become increasingly popular in many applications such as environment monitoring and law enforcement. Data aggregation is a method used to reduce network traffic but cannot be used together ...
-
(University of Pretoria, 2013)The use of databases has become an integral part of modern human life. Often the data contained within databases has substantial value to enterprises and individuals. As databases become a greater part of people’s daily ...
-
(University of Pretoria, 2007-01-24)HF communication has been used for more than a century and to this day still fulfils an important function in communications networks. In order to interface with modern communications protocols, solutions have to be designed ...
-
(University of Pretoria, 2006-09-23)Applications that use directory services or relational databases operate in client-server mode where a client requests information from a server, and the server returns a response to the client. Communication between each ...
-
The design of a simple energy efficient routing protocol to improve wireless sensor network lifetime (University of Pretoria, 2007-01-24)The number of potential applications for wireless sensor networks is immense. These networks may consist of large numbers of low cost, low power, disposable sensor nodes that can be deployed inside or close to phenomena ...
-
(University of Pretoria, 2008-07-22)This document discusses the concept of drivers implemented within the context of the REMPLI (Real-Time Energy Management over Power line and Internet, see section 1.8.) network. The process image approach and the tunnelling ...
-
(University of Pretoria, 2017)Endpoint devices are integral in the realisation of any industrial cyber-physical system (ICPS) application. As part of the work of promoting safer and more secure industrial Internet of Things (IIoT) networks and devices, ...
