—Mobile Adhoc Network (MANET) consists of a collection of wireless mobile hosts without the required intervention of any existing infrastructure or centralized access point such as base station. The dynamic topology of MANET allows nodes to join and leave the network at any point of time. Wireless MANET is particularly vulnerable due to its fundamental(More)
VANETs (Vehicular Ad hoc Networks) are highly mobile wireless ad hoc networks and will play an important role in public safety communications and commercial applications. In VANET nodes which are vehicles can move safety with high speed and must communicate quickly and reliably. When an accident occurs in a road or highway, alarm messages must be(More)

Multiple Sequence Alignment is one of the most useful tools in bioinformatics. It is widely used to identify conservation of protein domains, RNA secondary structure and classification of biological sequences. However, it is recognized as one of the most challenging tasks in bioinformatics. Evolutionary algorithms are providing competitive solutions for(More)
Recently, a popular metaheuristic algorithm called Harmony Search, conceptualized using the musical process of searching for a perfect state of harmony is undergoing faster developments. In this paper, a new variant of harmony search called Dynamic Hybrid Harmony Search algorithm (DHHS) is proposed. The novelty introduced in this algorithm is the division(More)
In the new restructured electricity power industry, a Generation Company (GENCO) with thermo-electric amenities faces the optimal problem of how to attain a maximum profit by considering the price uncertainties. In deregulated power markets, the maximization of profit is different from the minimization of cost because generation companies no longer have the(More)
– This paper presents a new approach with artificial immune system algorithm to solve the profit based unit commitment problem. The objective of this work is to find the optimal generation scheduling and to maximize the profit of generation companies (Gencos) when subjected to various constraints such as power balance, spinning reserve, minimum up/down time(More)
WSN have attracted a great deal of research attention due to then wide range of applications. The life span of the sensor network is limited to its residual power. In order to increase the energy of the nodes it is necessary to implement energy algorithms. Current work is focused on two main issues: the problem which occurs in the multipath routing and how(More)
