WiMAX, based on the IEEE 802.16 standard, is designed to support a variety of applications, including voice and multimedia services, through scalable OFDMA, advanced antenna techniques supporting MIMO, and well-defined quality of service classes. This paper presents WiMAX downlink achievable user goodput and operating range for different modulation and(More)
In cases when system load approaches capacity (>90% of capacity), scarce radio resources are wasted when a scheduler serves video packets that exceed a required latency, as the decoder will ultimately discard any such packets. In this paper, we introduce a combination of a packet-dropping policy with a modified Greedy-based scheduler to guarantee meeting(More)
Quality of Service is particularly necessary to serve delay-sensitive applications in heavy-loaded wireless networks. In this paper we evaluate a strategy of combining packet dropping and scheduling policies at Medium Access Control layer in guaranteeing maximum packet latency for real-time applications. The purpose of this work is to evaluate how(More)
Inter-Cell Interference (ICI) is a challenging problem for the next generation wireless systems which limits the system performance, especially for users located at the edge of a cell. In this paper, in order to achieve good user fairness, each user is given a guaranteed minimum number of resource blocks while the cell edge users were given a higher(More)
On behalf of the Committee, it is my great pleasure to welcome you to the 1st International Conference on Telematics and Future Generation Networks, Kuala Lumpur, Malaysia, 26 – 28 May 2015. The conference includes six technical sessions: IoT and Cognitive Radio, Future Generation Networks, Fundamental and Physical Layer, Future Antenna Design,(More)
Recently, an acoustic method is used in a water industry to detect and localise the leak in the water pipeline. However, the acoustic leak detection is only feasible for the metal pipes and has several limitations when applied to soft materials like plastic pipes. The objective of this paper is to investigate the accuracy of leakage detection for an(More)
This paper presents a numerical study to quantify the benefits of using Radio Environment Maps (REM) within resource management techniques. To date, there are no REM studies established to benchmark the impact of REM models and their accuracy for inter-cell interference coordination (ICIC) within multi-channel systems, such as based on OFDMA (Orthogonal(More)
