Enhanced Practical Wireless Communications Education via Blended Instructional Tools

Nursing Students Viewpoints toward Routine Instructional Tools

Introduction: Instructional tools are among effective factors in learning. Learning about students viewpoints towards these tools could help teachers in choosing the most appropriate one. This study was performed to investigate and compare students views towards three routine instructional tools including PowerPoint, overhead, and whiteboard. Methods: In this descriptive study in the year 2007,...

Secure Wireless Communications via Cooperative Transmitting

Information-theoretic secrecy is combined with cryptographic secrecy to create a secret-key exchange protocol for wireless networks. A network of transmitters, which already have cryptographically secured channels between them, cooperate to exchange a secret key with a new receiver at a random location, in the presence of passive eavesdroppers at unknown locations. Two spatial point processes, ...

An instructional model for web-based e-learning education with a blended learning process approach

Web-based e-learning education research and development now focuses on the inclusion of new technological features and the exploration of software standards. However, far less effort is going into finding solutions to psychopedagogical problems in this new educational category. This paper proposes a psychopedagogical instructional model based on content structure, the latest research into infor...

Load-Adaptive Practical Multi-Channel Communications in Wireless Sensor Networks

In recent years, a significant number of sensor node prototypes have been designed that provide communications in multiple channels. This multi-channel feature can be effectively exploited to increase the overall capacity and performance of wireless sensor networks (WSNs). In this paper, we present a multi-channel communications system for WSNs that is referred to as load-adaptive practical mul...
