Vehicle accidents are one of the most leading causes of fatality. The time between an accident occurrence and the emergency medical personnel are dispatched to the location of accident is the critical factor in the survival rate after an accident. By minimizing the gap time, mortality rate can be reduced. One approach to reduce the delay time is to use the Real Time Wireless Accident Tracker Using...
This paper presented an enhanced of SINR based on serving and neighboring path loss to mitigate co-channel interference by using DSSS technique in LTE-Wi-Fi network. The proposed technique is the continuity from the earlier work which enhanced the DSSS with new coefficient: chip rate coefficient and radius fraction coefficient. The earlier works only consider its serving BS for path losses values...
Haze has becoming a yearly occurrence in Malaysia. There exist three dimensionsto the problems associated with air pollution: public ignorance on quality of air, impact of air pollution towards health, and difficulty in obtaining information related to air pollution. This research aims to analyse and visually identify areas and associated level of air pollutant. This study applies the air pollutant...
In this rapidly modernizing era, haze or air pollution is one of the many serious global problems for the entire population in the world. Air pollutant index (API) reading increases as haze gets worse, affecting school and aircraft schedule on top of causing respiratory problem. However, there have been occasions in Malaysia where API level published by Department of Environment (DoE) does not change...
Self-Organizing Network (SON) mechanism comprises of three components of self-configuration, self-optimization and self-healing which can contribute to optimize the performance of the next generation broadband network such as the Long Term Evolution (LTE) networks. The aim of this study is to propose a self-organizing handover procedure based on the Self-Organizing Network (SON) concept for LTE network...

This paper investigates a novel structure of a reconfigurable microstrip antenna integrated with the aperture coupling technique which can reduce spurious radiation pattern with stacked patch in order to enhance the gain and bandwidth performance. The antenna design implements a new concept of the frequency reconfigurability methods applying in an aperture-coupled technique. Four PIN diode switches...
Land use and land cover classification of remotely sensed data is an important research and commonly used in remote sensing application. In this study, the different types of classification techniques were used by using satellite image of some part of Selangor, Malaysia. For this objective, the land use and land cover was classified with Landsat 8 satellite image and ERDAS Imagine software as the...
In cellular network, it is predictable that 2/3 of calls and more 90% data services take place indoors. Because of that reasons, the User Equipment (UE) will having serious problem regarding on capacity achieving in indoors place. Due to this scenario, the femtocell is deployed in order to provide a good indoor coverage. However, deployment of femtocells pose a number of challenges and one of it is...
Long Term Evolution (LTE) network is the latest technology before the presence of Advanced-LTE (LTE-A). LTE is introduced by 3rd Generation Partnership Project (3GPP) to improve the mobile phone standard to cope with future technology evolutions and needs. Recently, femtocell which known as Home NodeB (HNB) is the remarkable technology network that implanted in the LTE network in order to fulfill...
The most famous and known effects of space weather is fluctuation in the amplitude and phase radio signal that propagates in the ionosphere. This fluctuation is also known as scintillation which will intense, degrades the signal quality, reduce the information content, or cause failure of the signal reception. During solar eclipse day, there are some fluctuations to the signal received by GPS (Global...
This paper present about the fire detection of forest fire at Raja Muda Forest Reservein Kuala Selangor within the year2005 until 2009. The main objective is to detect the relationship of humidity and temperature in the effect of the recovery of the forest fire. There are some approaches to identify the effect of the vegetation recovery, Byusing Anova Method, pattern prediction and Remote Sensing...
In telecommunications, Received Signal Strength (RSS) defines as a measurement of the power present in a received radio signal. Users are likely to expect uninterrupted, efficient and stable service starting from the day their subscribe into the network. For these reasons, in order to provide uninterrupted service, it is required to do the performance testing. The main focus of research in this paper...
Radio resource partitioning is a vital feature that ought to be considered to further enhancing the overall performance of the Orthogonal Frequency Division Multiple Access (OFDMA) system. Radio resources can be allocated in either time domain or frequency domain in OFDMA system. As the emergence recent technologies such as femtocell, which is it underlay the macrocell network, the users fairness...
This paper studied the TEC values for Malaysia regions, a few location of GPS receiver stations were chosen‥ The transmitted GPS signals must propagate through the ionosphere layer at the atmosphere before reaching the surface. The ionosphere layer can cause the effect of the GPS due to the electron density at this layer. It is the main source of error in the GPS positioning. The problem is considered...
Depletion layer in Total Electron Content (TEC) in ionospheric layer called plasma bubbles which usually occur during midnight. Plasma bubbles have been studied using different techniques including incoherent backscatter radar, ionogram analysis, airglow detection, rocket soundings and Global Positioning System (GPS) network phase fluctuations. This research is focus on the observation of equatorial...
The 3GPP LTE system has been premeditated to offer extensively higher data rates, higher system throughput, and lower latency for delay critical services. This enhanced performance has to be provided and assured under various mobility circumstances. But, an inappropriate setting of input parameter such as hysteresis margin will lead to an extensive number of handover failures. Hence, handover and...
This research presents the TEC value based on location of the receivers in Malaysia. Many research group in several countries done their research in VRS concept, algorithm, performance, accuracy and method of transmitting the correction to the rover. This is because VRS has become most popular solution in network RTK which symbolizes the new stage of precise GPS positioning. The target is to calculate...
Tweek atmospherics are ELF/VLF pulse signals with frequency dispersion characteristics generate from lightning discharges and spread in the Earth-ionosphere waveguide mode. This study uses the electromagnetic wave approach describe as ELF (extremely low frequency) and VLF (very low frequency) which propagates sub-ionospherically among the earth and the lowest ionosphere. This paper presents the nighttime...
Nowadays the demand for cellular mobile phone has grown rapidly. If the cellular user population is increase there is a need to maximize the number of subscriber in the system. To achieve the goals of maximizing network capacity, hierarchical topology cell is being studied. In this hierarchical topology cell, femtocell is overlaid over the macrocell to handle overflow calls. Mobile subscriber is divided...
