Computer Science 2 is one of the core elements of any computer science program; however, there has been little progress towards the development of a concept inventory for this key introductory course for CS majors. Plans to address this gap using the Delphi method are presented. Instructors and researchers with knowledge and experience of CS2 are being recruited to help identify concepts from CS2...
One of the more obvious ways to reduce the volume of data traffic on cellular networks is through the use of handover to fixed networks via WiFi and other radio channels. With the growing focus on emerging 5G concepts and technologies, there has been a corresponding focus on the functional mechanisms needed to achieve this handover in a timely fashion. Much less attention has been paid to the practicalities,...
Consistent, unified time knowledge and associated clock synchronisation are key elements of many future Wireless Sensor Network deployment scenarios. Reliable synchronisation is necessary for applications that involve distributed tasks, such as medium access control involving sleep cycles for smart power management, precise sensor sampling, WSN control and actuation, data sequencing and aggregation...
Over the past two decades, one of the key changes in Engineering curricula has been in the emphasis placed on the development of personal transferable skills. Employers also profess to seek these competencies when making recruiting decisions. Such skills include the ability to learn through collaboration and through meaningful critical reflection on one's own performance, both as an individual and...
This paper reports on the category of “self-affirmation”, one of the key abstracted categories identified in a qualitative study that sought to examine the factors that influence student perception of success in undergraduate Computer Science. Self-affirmation is the process whereby an individual focuses on important and positive aspects of their life with the aim of affirming their sense of self-worth...
Quality-oriented network service provisioning can take place at the network level using estimates of Intrinsic Quality of Service (IQoS) parameters or at the user level through measurements of the end-user Quality of Experience (QoE). While IQoS parameters are quantitative and measurement based, QoE estimates are more difficult to obtain as they usually rely on subjective end-user reporting.
Congestion management is a key factor in the provision of acceptable levels of quality of service (QoS) on wired networks. However, the concept of congestion management does not translate easily into the wireless domain. Active Queue Management (AQM) solutions for congestion avoidance have proved effective in wired networks but have not gained much traction in the wireless world. Wireless AQM schemes...
