This paper introduces the implementation of IEEE 802.22 Wireless Regional Area Network (WRAN) for broadband internet access in rural areas. It highlights the advantage of implementing such technology and feasibility to co-exist with Digital Video Broadcasting – Terrestrial (DVB-T) in Malaysia. It adopts a model to determine the maximum number of(More)
This paper examines the implementation of the Singular Value Decomposition (SVD) method to detect the presence of wireless signal. The method is used to find the maximum and minimum eigenvalues. We simulated the algorithm using common digital signal in wireless communication namely rectangular pulse shape, raised cosine and root-raised cosine to test the(More)
Alzheimer‘s disease is one of the leading diseases that contribute to dementia cases. The Alzheimer‘s patient suffers from memory loss and losing judgment due to its effect on the human brain. Alzheimer‘s patients need to be monitored and assisted in their daily life especially for medication. Proper medication may reduce the effect of Alzheimer‘s disease(More)

The demand for Internet services and network resources in Educational networks are increasing rapidly. Specifically, the revolution of web 2.0 “also referred to as the Read-Write Web” has changed the way of information exchange and distribution. Although web 2.0 has gained attraction in all sectors of the education industry, but it results in high-traffic(More)
This paper highlights an algorithm for detecting the presence of wireless signal using the Singular Value Decomposition (SVD) technique. We simulated the algorithm to detect common digital signals in wireless communication to test the performance of the signal detector. The SVD-based signal detector was found to be more efficient in detecting a signal(More)
The tremendous growth of mobile computing in recent years has created a lot of interesting potentials for digital economy activities. However, the mobile computing constitutes of various complexities in many forms or types. These heterogeneities have posed various challenges in creating an ensemble environment where multiple heterogeneous mobile devices can(More)
Grid systems provide geographically distributed resources for both computational intensive and data-intensive applications. These applications generate large data sets. However, the high latency imposed by the underlying technologies; upon which the grid system is built (such as the Internet and WWW), induced impediment in the effective access to such huge(More)
Wireless sensor network (WSN) have become one of the most promising technology in sensing application environment. WSNs environment are able to provide a flexible deployment and maintenance of sensor networks. The sensor nodes can be deployed in highly dynamic environments and hence enable sensor networks to be potentially used in a wide range environment(More)
This paper gives a study on parallel downloading of UUM‘s network performance. It considers the response time of the downloaded files from within UUM‘s local network to the outside Internet connection. In order to study the performance of downloading method, other methods will be used as a comparison. The other downloading methods that have been used are(More)
