A Mobile Ad hoc network (MANET) is a dynamic selforganizing 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)
Boosting is a well known and efficient technique for constructing a classifier ensemble. An ensemble is built incrementally by altering the distribution of training data set and forcing learners to focus on misclassification errors. In this paper, an improvement to Boosting algorithm called DivBoosting algorithm is proposed and studied. Experiments on(More)
Bagging is a well known method for designing classifier ensembles. It builds an ensemble of classifier trained on different bootstrap replicates of the training data set. In this paper an improvement to bagging algorithm called DivBagging is presented and studied in depth. The experimental results show that DivBagging is a promising method for ensemble(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)
Numerous fast-search block motion estimation algorithms have been developed to circumvent the high computational cost required by the full-search algorithm. These techniques however often converge to a local minimum, which makes them subject to noise and matching errors. Hence, many spatial domain block matching algorithms have been developed in literature.(More)
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)
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)
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 stateof-the art Reed-Solomon (RS) codes. Algebraic-Geometric Codes are proposed and implemented in this paper. The design,(More)
Attribute reduction (AR) represents a NP-hard problem, and it is be identified as the problematic issue of pinpointing the least (possible) subset of characteristics taken from the reference set. The key issue related to characteristics selectors is the production of a minimal number of reductions representing the reliable meaning of all characteristics.(More)
