In this article, we propose and study a self-switching network concept known as an ingenious multiple communicator mechanism which can be applied to energy provider’s smart metering device. We outline reasons why such multiple connections networks are required through real case study scenarios and key components that drive towards such concept. We have gathered actual measurement values for a particular network and identified in what situation this is most suitable and applicable. We have come out with the basic system model for this multiple communicator. We also observed that a less fluctuating and similar pattern of network performance helps to design better network predictive analytics function. Finally numerical examples and analysis of the results are presented.

Mohammad Kamrul Hasan,Ahmad Fadzil Ismail,Shayla Islam,Wahidah Hashim 보안공학연구지원센터 2016 International Journal of Hybrid Information Techno Vol.9 No.7
This paper studied the power allocation and downlink interference issues in orthogonal frequency-division-multiple-access (OFDMA) system to mitigate the interference issues. In Orthogonal Frequency Division Multiplexing Access (OFDMA) frameworks, resource allotment to the subcarrier is crucial attributable to the deficient assets accessible at the base station. In OFDMA, subcarrier and power distribution are not separate, along with these lines this two portion are not self-overseeing. This paper examines the power allo-cation approach through exploring the HGBBDSA approach. The integration of GA with Biogeography Based Optimization algorithm benchmarked over the Particle Swarm Op-timization (PSO). The both of the algorithms cross usefulness is evaluated and looked at the exhibitions in Heterogeneous Network (HetNet). The reenactment results demonstrate that the HGBBDSA approach efficiently allocates the power than that of existing PSO approach.

An analysis based on rainfall rate characteristics has been carried out to estimate flood occurance. In this paper, we analyzed the rain gauge data for 5 different rain gauge stations. 14 days acquired data covering events before, during and after the flood tragedy in Malaysia. The analysis of the rain gauge data was processed on precipitation phenomena observed in year 2014 in Kota Bharu, Kelantan (Malaysia) from 13 December until 26 December. The data was acquired from the Malaysian Drainage and Irrigation Department (DID). The objective of the research is to derive the tropical flood estimation model using rain gauge data in Malaysia. Among the preliminary result shows that the average rainfall rate at kota bharu is 204.5 mm/hr during the flood tragedy.

In orthogonal frequency division multiplexing Access (OFDMA) systems resource allocation to the subcarrier is essential owing to the insufficient resources available at the base station. In OFDMA, subcarrier and power allocation are not separate; thereby this two allocation are not self-governing. This paper proposes the subcarrier allocation approach through investigating previous methods, and also the Enhanced Particle Swarm Optimization (PSO) algorithm is analyzed. The both of the algorithms cross functionality is analyzed and compared the performance of the subcarrier allocation of OFDMA systems in Heterogeneous Network (HetNet). The simulation results show that the PSO approach efficiently allocates the OFDMA subcarriers.
Development of a River Basin Monitoring System for Malaysia

Flood is a natural disaster that can destroy and damage a lot of properties, infrastructures, facilities, homes, vehicles and can even cause loss of lives. To minimize the hazard risk and loss due to the floods, intensive measures have to be considered. Monitoring any drastic changes in water level or river stage at river basin may not prevent the flood, but this measure benefits the community as early prediction of flood can be done before the water reaches the general population. This paper discusses the development of an informative and interactive river basin monitoring system for online hydrological stations in Kelantan, Malaysia. The first trial version has been assembled using Visual Basic.
Biogeography-based Interference Mitigation Scheme for OFDMA System in Heterogeneous Network
Mohammad Kamrul Hasan,Ahmad Fadzil Ismail,Aisha-Hassan Abdalla,Wahidah Hashim,Shayla Islam 보안공학연구지원센터 2016 International Journal of Multimedia and Ubiquitous Vol.11 No.10
In Heterogeneous Network (HetNet), the small base station such as femtocells are deployed in indoor and multiple business complexes in order to extend the coverage and capacity. The deployment of co-channel (i.e. shared channel) for femtocells along with macrocell induces the severe interference issues. This is because of effects on SINR and thereby capacity become deteriorated. Therefore, this paper investigates the interference mitigation techniques and come out with a proposal to improve the Signal to Interference Noise Ratio (SINR) performance as well as total capacity in Heterogeneous Network (HetNet).The simulation results show that the achieved capacity is maximized than the existing technique.

As the rate of internet users is increasing on a daily basis, a tremendous amount of these users are accessing online streaming websites and applications. This paper proposes a live streaming architecture that supports traffic balancing during peak times and bitrate adaptation. Rather than replicating content on multiple servers, we implemented traffic balancing by assigning a temporary regional server to manage the traffic at regional area. Bitrate adaptation at server side was also proposed and implemented to provide a fair video quality to all users. Through a few tests that has been run on the testbed, we can see the live video streaming was move seamlessly from one server to another server with an acceptable video quality among the users.
Daily Activity Monitoring of an Elderly Person for Determining Their Wellness

The work carried out in this paper aims to present a model based on elderlies daily activities to determine their wellness status. A wellness function is delineated to estimate the health condition of the aged individuals while carrying out their day-to-day routine. The proposed model can also be used to monitor the mobility parameters, such as entry and exit of a room and bed occupancy of an elderly. Simple sensors such as capacitive sensors are equipped into their homes to monitor their behaviour and identify their daily activities via non-contact means. The device will allow extracting daily behavioral patterns of the elderly person. Thus the device will help in providing information to build behavioral model of the person which can foresee the anomalies in their behaviour. In case the elderly is distressed, an alarm can be sent to a receiver unit. The cost effectiveness of the device will ultimately lower the total cost of wellness monitoring of an elderly person. A prototype of the device can be fabricated and broadly tested for extracting precise results.
