GLOBECOM - Enhancing the channel utilization of asynchronous data traffic over the Bluetooth wireless ad-hoc network
Global Telecommunications Conference 2002. GLOBECOM '02. IEEE, 2002Co-Authors: Jain-wei WuAbstract:Bluetooth is an emerging technology to build a solution for providing short range, low power, low cost, and ubiquitous wireless environments. We propose an algorithm for asynchronous data traffic at the medium access control (MAC) layer to meet Bluetooth characteristics. We compare it with other scheduling algorithms. The algorithm, named efficient utilization polling (EUP), uses a single bit of the Payload Packet header as supplied knowledge of queues of slaves to the master to adapt the polling intervals dynamically. We also propose a differentiation mechanism, named shifting polling window (SPW); it is based on EUP and differentiates throughput among different classes and still keeps the link utilization almost the same.

TENCON - Performance Evaluation of Several Interest Flooding Attack (IFA) Countermeasure Method on ISP-like Topology for Named Data Networking
TENCON 2018 - 2018 IEEE Region 10 Conference, 2018Co-Authors: Marion Renaldo Rotinsulu, Riri Fitri SariAbstract:IEEEThe prerequisites of the fifth-generation network (5G) is the latency of 1–10 ms, to work with wide range of bandwidth start from 100 Mbps to 10 Gbps. We studied Named Data Networking (NDN) resistance against attacks that can interfere with the availability of the network. One of the potential threats to NDN is the Interest Flooding Attack (IFA). IFA is similar to the Denial of Services (DoS)/Distributed Denial of Services (DDoS) on IP-based networks. In this paper, we evaluate the IFA against varied data Payload, round-trip time, the duration of attack, and range of allocated bandwidth with goal to determine the parameter that could affect the performance issue of the mitigation system. We do this works using a custom Rocketfuel ISP-like topology that has been ported to NS-3 and ndnSIM version 1.0. We run the simulation on Ubuntu 14.04.5 32 bit. The experiment results show that the Satisfaction Pushback countermeasure method is more reliable on facing IFA attacks. The duration of attacks, RTT values and data Payload Packet size have a significant impact in certain simulation condition. The "great" combination of these three parameters could reduce the network performance up to 63%.

Fault-Tolerant Routing Mechanism in 3D Optical Network-on-Chip Based on Node Reuse
IEEE Transactions on Parallel and Distributed Systems, 2020Co-Authors: Luan H. K. DuongAbstract:The three-dimensional Network-on-Chips (3D NoCs) has become a mature multi-core interconnection architecture in recent years. However, the traditional electrical lines have very limited bandwidth and high energy consumption, making the photonic interconnection promising for future 3D Optical NoCs (ONoCs). Since existing solutions cannot well guarantee the fault-tolerant ability of 3D ONoCs, in this paper, we propose a reliable optical router (OR) structure which sacrifices less redundancy to obtain more restore paths. Moreover, by using our fault-tolerant routing algorithm, the restore path can be found inside the disabled OR under the deadlock-free condition, i.e., fault-node reuse. Experimental results show that the proposed approach outperforms the previous related works by maximum 81.1 percent and 33.0 percent on average for throughput performance under different synthetic and real traffic patterns. It can improve the system average optical signal to noise ratio (OSNR) performance by maximum 26.92 percent and 12.57 percent on average, and it can improve the average energy consumption performance by 0.3 percent to 15.2 percent under different topology types/sizes, failure rates, OR structures, and Payload Packet sizes.

Wavelet-based Encoding Scheme for Controlling Size of Compressed ECG Segments in Telecardiology Systems
Journal of Medical Systems, 2017Co-Authors: Asiya M. Al-busaidi, Lazhar Khriji, Farid Touati, Mohd Fadlee Rasid, Adel Ben MnaouerAbstract:One of the major issues in time-critical medical applications using wireless technology is the size of the Payload Packet, which is generally designed to be very small to improve the transmission process. Using small Packets to transmit continuous ECG data is still costly. Thus, data compression is commonly used to reduce the huge amount of ECG data transmitted through telecardiology devices. In this paper, a new ECG compression scheme is introduced to ensure that the compressed ECG segments fit into the available limited Payload Packets, while maintaining a fixed CR to preserve the diagnostic information. The scheme automatically divides the ECG block into segments, while maintaining other compression parameters fixed. This scheme adopts discrete wavelet transform (DWT) method to decompose the ECG data, bit-field preserving (BFP) method to preserve the quality of the DWT coefficients, and a modified running-length encoding (RLE) scheme to encode the coefficients. The proposed dynamic compression scheme showed promising results with a percentage Packet reduction (PR) of about 85.39% at low percentage root-mean square difference (PRD) values, less than 1%. ECG records from MIT-BIH Arrhythmia Database were used to test the proposed method. The simulation results showed promising performance that satisfies the needs of portable telecardiology systems, like the limited Payload size and low power consumption.
