Satellite is often used as an access network in the Next Generation Networks landscape, where multimedia and real-time services are supported by return channels. However, these satellite return channels are a very limited resource with many terminal stations competing for its use, making its efficient assignation one of the key problems to solve in order to increase network performance. This ar...

This paper presents the application of genetic algorithms (GAs) as a means of inducing solutions to the ClassTeacher Timetabling Problem (CTTP). Timetabling problem in almost all research focus on solving the hard constraints. This is an attempt to satisfy as many soft constraints as possible, as soft constraints are varying in nature. Initially the population is created depending on the number...

This paper proposes a hybrid algorithm that combines two prominent nature-inspired meta-heuristic strategies to solve the combined heat and power (CHP) economic dispatch. In this line, an innovative heap-based jellyfish search (HBJSA) is developed enhance performance of recent algorithms: (HBA) (JSA). The proposed HBJSA seeks make use explorative features HBA exploitative JSA overcome some prob...

the range imaging based on conventional pulse compression technique requires lfm signal that sampled by nyquist rate. in order to high resolution increased in range in pulse compression, so the lfm bandwidth has to increase. consequently this procedure dictated limitations on adc sampling. the stretch processing is one of techniques decreasing nyquist rate in radars. in this method the nature o...

An innovative ant colony algorithm called memory-based ant colony algorithm is proposed to solve the bipartite subgraph problem. In the proposed algorithm, artificial ant has memory of solution found previously, and can use it to construct a new solution. Besides, in the proposed algorithm two kinds of pheromone and two kinds of heuristic information are also adopted to reinforce the search abi...

in this paper, we propose an iterated greedy algorithm for solving the blocking flow shop scheduling problem with total flow time minimization objective. the steps of this algorithm are designed very efficient. for generating an initial solution, we develop an efficient constructive heuristic by modifying the best known neh algorithm. effectiveness of the proposed iterated greedy algorithm is t...

In this paper we introduce an innovative technique for localization purpose in IEEE 802.11 networks, [1]. Our location algorithm is based on the distance estimation performed by three Base Stations (BSs), employing the triangulation process to calculate the mobile user position. This method results innovative and efficient both for the IEEE802.11 PCF and DCF phases to track the user position at...

GPS signals are susceptible to interference levels above the inherent processing gain of the receiver. In this paper an innovative approach to cancel narrowband interference is presented. An Adaptive Temporal Filter (ATF) based on a Transversal form that pre-filters the interference before correlation is studied. The adaptive algorithm used to adjust the filter coefficients is the RLS algorithm...
