Mobile Multihop Relay (MMR) network is an attractive and low-cost solution for expanding service coverage and enhancing throughput of the conventional single hop network. However, mobility of Mobile Station (MS) in MMR network might lead to performance degradation in terms of Quality of Service (QoS). Selecting an appropriate Relay Station (RS) that can support data transmission for high mobility MS to enhance QoS is one of the challenges in MMR network. The main goal of the work is to develop and enhance relay selection mechanisms that can assure continuous connectivity while ensuring QoS in MMR network using NCTUns simulation tools. The approach is to develop and enhance a relay selection for MS with continuous connectivity in non-transparent relay. In this approach, the standard network entry procedure is modified to allow continuous connectivity with reduced signaling messages whenever MS joins RS that is out of Multihop Relay Base Station (MRBS) coverage and the relay selection is.....

The use of technology in creating Teaching Aids (TA) for the Teaching and Learning (TL) process has a great impact on delivering knowledge and skills as well as expediting the learning process amongst students. Additionally, game-based TA plays an important role in improving the achievement and efficiency of students in the classroom. This research was conducted to develop the education kit for TL Resistor Color Code (RCC). The main purpose of this education kit development is to help students understand the RCC through a fun learning environment based on hands-on learning activity. This education kit known as Resistor Value Checker (RVC) kit is built on the concept of 21st Century Learning (21-CL) which concerns about the use of appropriate technology in the process of the TL in the classroom. It is designed with the latest facilities and different from existing products in the market...
