Routing protocol in ad hoc networks essentially needs a routing mechanism to establish a path from source to destination. The protocols differ in techniques used to discover path and recover in case of failure. Traditional routing protocol such as AODV, DSR, DSDV, OLSR, and AOMDV have been found to perform efficiently in the networks without consideration of battery power or network life time. This...
Inter Process Synchronization is aimed at providing interrupt free and deadlock free well-structured communication among processes. The approach used is generally non-agent oriented approach which may lead to deadlock situation. This paper analyzes the runtime performance of non-agent based solution to IPS Problem. In this paper the testing is carried out and the results are obtained under time intervals...
Holistic approaches of face recognition are not robust to illumination, scale, occlusion and age variations. Various studies indicate that the performance of holistic approaches degrades as the face database size increases. In this paper, we propose a user specific landmark geometry based approach that assigns weights to different geometrical distances according to their role in face recognition process...
Vehicular ad-hoc networks (VANETs) provides infrastructure less, rapidly deployable, self-configurable network connectivity. The network is the collection vehicles interlinked by wireless links and willing to store and forward data for their peers. As vehicles move freely and organize themselves arbitrarily, message routing is done dynamically based on network connectivity. Compared with other ad-hoc...
This paper evaluates the effect of applying well known mutation and crossover operators of Genetic algorithm in Mobile Ad-hoc NETworks (MANETs). In this paper, we propose an approach to develop an algorithm for an efficient routing in MANETs. A wireless ad-hoc network can be defined by a collection of mobile nodes, connected over a wireless medium. Genetic algorithm is an evolutionary optimization...
With the increased complexity in number of applications and due to large volume of availability of data from heterogeneous sources, there is a need for the development of suitable ontology, which can handle the large data set and present the mined outcomes for evaluation intelligently. In the era of intensive data driven applications distributed data mining can meet the challenges with the support...
In general, performances of routing protocols are analyzed through simulation. Tools like statistical design of experiments also provide a variety of significant outcomes. To improve the functioning of routing protocols it is required to evaluate the factors that affect its performance. Such evaluation is carried out with the help of response metrics. Two kinds of evaluation are possible: single-response...
This paper presents a method for test cases generation from a state machine. This paper investigates variable chromosome length genetic algorithm for automatically generating state based test cases. For efficiency we developed a Genetic algorithm that optimize and select test case which are covering maximum number of states and transitions on distinct chromosome length. Variable chromosome Length...
One of the biggest challenges in behavioral biometric systems is to select biometric features for pattern construction due to large domain of user's behavior. It is desirable that, behavioral pattern should be as small as possible for low computational cost of the system. But reduced pattern size costs accuracy of the authentication system. In this paper, authors have proposed to select user specific...
There is growing tendency of users to use web application in place of desktop application because of technological advancement such as AJAX. AJAX is used to build single page web application because content and structure can be changed using AJAX features like Asynchronous communication and run time DOM manipulation. To understand and analyze extreme dynamism of web application, we implemented a tool...
This paper presents a proficient technique to test all static and dynamic analysis of chosen web application using state machine and variable chromosome length genetic algorithm. We propose a framework to generate user session based state machine model of dynamic behavior of a web application and the technique used to test the correctness of generated state machine is Variable chromosome length genetic...
Dynamic Content of a Web Application gives acclivity to whole set of new challenges in the field of web application testing. After canvassing several approaches on how to effectively test Dynamic Web Applications, We found that an effective way to counter the web application dynamic content testing exceptions is using the combined approaches of state-based testing and user session based testing. In...
In computing, Inter-process communication (IPC) is a set of methods for the exchange of data among multiple threads in one or more processes. Operating system works as an inter process synchronization manager (IPSM). In the present paper agent based inter process synchronization manager is described and its performance is compared with other non agent based IPSM on different operating systems.
A query optimizer is a core component of any Database Management System. As a database query optimizer might face different voluminous and complex queries, leading to a huge search space of alternative query plans, it should be appropriate to adapt the search strategy to the problem solving technique which handles complex and large data. Genetic Algorithms (GAs) avoid the high cost of optimization...
