The proposed research topic concerns a unique situation in several Asian countries because the drainage systems in these countries differ notably from those in the US and Europe in that the former are partially open on the top while the latter are primarily below ground and covered. Measurement results are reported for one drain located on Sunway University campus at 2.4 and 5.8 GHz. The differences between the measurement results at the aforementioned two frequencies are discussed. These measurement results serve as a useful indicator as to how signal might behave differently in partially enclosed spaces, such as those where partially open drains exist, especially in an urban environment.

The efficiency of a DAR algorithm can then be defined as the accuracy of data reformation against the percentage of the abstracted data over the full data.

Optimum sensor node placement in the surveillance area is needed since the number of sensor nodes that can be deployed are limited. The positions of sensor nodes must be able to provide maximum coverage with a longer lifetime. This paper describes an initial stage of an ongoing project. A Sensor node placement technique which is based on the minimax algorithm is proposed where surveillance locations will be monitored by the closest sensor nodes. Performance study has been carried out by evaluating the performance of the minimax scheme in terms of coverage ratio and uniformity. Uniformity is a performance metric that can be used to estimate WSN lifetime. Simulation results show that WSN with higher sensor nodes will provide a higher coverage ratio and more uniformly distributed sensor nodes.

A centralized CR system is an architectural model for a wide range of applications for example wireless medical telemetry service and medical implant communications service. As an enabling technology for white space exploitation, context awareness and intelligence (or cognition cycle, CC) remains the key characteristics of CR for using the underutilized licensed spectrum in an efficient manner. In this paper, we provide investigation into the application of a stateful Reinforcement Learning (RL) approach, to realize the conceptual CC in centralized static and mobile networks in the presence of many PUs. We investigate the use of RL with respect to Dynamic Channel Selection (DCS) that helps the SU Base Station (BS) to select channels adaptively for data transmission between different SU hosts. The purpose is to enhance the Quality of Service (QoS), particularly to maximise throughput and reduce delay by means of minimizing the number of channel switches. Simulation results reveal that RL achieves good performance and that the learning and exploration characteristics should converge to a low value to optimise performance.

As the numbers of users are expanding significantly, the traditional Client-Server architecture can't afford the number of growing users. Therefore the video quality of service and network scalability is become so deprived. Based on the demand of users and drawbacks of client-server architecture, institutes and researchers have provided effective solutions to contrive new application systems called Content Delivery Network (CDN) and Peerto-Peer (P2P) network. Recently, researchers have proposed a hybrid approach that amalgamates both CDN and P2P was proposed in the literature. The goal of this paper is to simulate and investigate the performance of hybrid CDN and P2P on live-casting video distribution, and contrast it against our propounded hybrid CDN and P2P with hierarchical arrangement called Dynamic Mobile Server (DMS), in terms of average frame loss ratio, packet loss ratio and peak signal noise ratio.

It is expected that the informatics will contribute to the development of various Vehicular Ad-hoc Network (VANET) applications such as motor or vehicular tailpipe emission modelling, minimizing traffic congestions including fuel consumption and intersection management.
