String matching is seen as one of the essential problems in computer science. A variety of computer applications provide the string matching service for their end users. The remarkable boost in the number of data that is created and kept by modern computational devices influences researchers to obtain even more powerful methods for coping with this problem. In this research, the Quick Search string matching algorithm are adopted to be implemented under the multi-core environment using OpenMP directive which can be employed to reduce the overall execution time of the program. English text, Proteins and DNA data types are utilized to examine the effect of parallelization and implementation of Quick Search string matching algorithm on multi-core based environment. Experimental outcomes reveal that the overall performance of the mentioned string matching algorithm has been improved, and the improvement in the execution time which has been obtained is considerable enough to recommend the multi-core environment as the suitable platform for parallelizing the Quick Search string matching algorithm.
Abstract. The technical design challenge of Mobile WiMAX is to exploit the limited available spectrum of the downlink subframe efficiently while achieving the desired goals behind the resource management algorithms. Various goals can be achieved when the resource management algorithms exploited in the right direction. This paper presents the coordination between MAC layer scheduler objectives and PHY layer burst allocation algorithm design parameters. Utilizing PHY layer operation mode with MAC layer coordination leads to increase the proportion of the desired objectives achievement. The presented methodologies of the burst allocation algorithm design can achieve higher satisfaction of MAC requirements and avoid the limitations. The study has demonstrated that resource allocation algorithm requires many factors and parameters to be employed in the correct direction to enable efficient use of the downlink resources to satisfy MAC layer requirements.
