A large-scale study of more than half a million Facebook posts suggests that members of online social networks can expect a significant chance of encountering spam posts and a much lower but not negligible chance of coming across malicious links.
The purpose of this study is to construct a near capacity Irregular-Turbo Code (I-TC) and to evaluate its performance over Gaussian channel. The methodology used to evaluate and measure the performance of the new design is by simulating the system by developing a software platform using MATLAB. The simulation carried out by implementing the system over… (More)
This paper will present the design, construction, and implementation of Algebraic-Geometric Irregular Block Turbo Codes (AG-IBTCs). Furthermore, we will evaluate its performance over fast fading channels using different modulation schemes (BPSK, QPSK, 16QAM, and 64QAM). The idea behind the design of AG-IBTC is to overcome the high system complexity of… (More)
This paper approaches the issues concerning the coexistence of the IEEE 802.11g wireless networks and the ad-hoc Bluetooth networks that operate within the same 2.4 GHz band. The performance of 802.11g is evaluated by simulating the PER (Packet Error Rate) parameter and coverage area. The simulation experiments are based on the worst case scenario… (More)
A Mobile Ad hoc network (MANET) is a dynamic self-organizing multi-hop wireless network. Owing the random and unpredictable movement of the mobile nodes, the topology is changing rapidly and frequently. In MANET, where is no routing infrastructure like fixed routers and routing backbones, all MNs participate in the routing process. Recently, position-aware… (More)
Algebraic-Geometric (AG) codes are new paradigm in coding theory with promising performance improvements and diverse applications in point to point communications services and system security. AG codes offer several advantages over state-of-the art Reed-Solomon (RS) codes. Algebraic-Geometric Codes are proposed and implemented in this paper. The design,… (More)
This paper will present in details the concept of block turbo design in Algebraic Geometric (AG) codes constructed from Hermitian curves defined over finite fields, and the iterative decoding of the constructed block turbo codes using a High Input-High Output (HIHO) decoding technique based on Sakata's algorithm with Majority Voting (MV) technique and… (More)
Telecommunication networks have become as critical to the 21st century development as were railways, roads and canals, to the 19th Century developments and is now seen as enabler to a more sustained business, environment and society as a whole. Still fascinating has been and is the exponential rate of growth in this industry. This is one sector where the… (More)
