In most of the shortest path problems like vehicle routing problems and network routing problems, we only need an efficient path between two points---source and destination, and it is not necessary to calculate the shortest path from source to all other nodes. This paper concentrates on this very idea and presents an algorithm for calculating shortest path(More)
—The main objective of the research is to introduce a biologically inspired execution framework for workflow systems under threat due to some intrusion attack. Usually vulnerable systems need to be stop and put into wait state, hence to insure the data security and privacy while being recovered. This research ensures the availability of services and data to(More)
The main objective of the research is to propose an execution framework for workflow systems under threat. When the threat (intrusion) is detected, the workflow system needs to be stopped immediately to avoid any possible loss of enterprise data. The system becomes active again, once it is completely recovered from the threat. This proposed framework(More)
IT industry despite the wide use of most modern tools and technologies has been unable to achieve targeted success. Awry situations in projects have become routine matter. Besides technical other factors influencing software development activities also need to be considered. Software development and consultancy organizations must realize the importance of(More)

Interaction among team resources during software development is an important aspect of a software project. The success and growth of a project mainly depends upon how effective interaction and coordination exists among all the team resources and client of a project. The importance of having a good interaction with client during software development process(More)
Latest global social, economic and technological changes have given birth to a new generation of software engineering practice. Traditional approaches of software development have become less popular. Software development by centrally located in-house teams has slowly been replaced by geographically distributed offshore teams. As such project outsourcing to(More)
Breadth First Search (BFS) can calculate the shortest path for un-weighted graphs very efficiently but when it comes to non-negative weighted graphs it fails at a point when a successor updates a predecessor. Such nodes are being referred as Culprit nodes in this research. These Culprit nodes are the ones that cause error in shortest path in an algorithm(More)
Since years software development industry is trying hard to show a remarkable performance in its project development work. Issues related to the software processes improvement, risk management, people's factors and effective project management still exist. Though academic researchers have produced good quality work on software industry issues, but(More)
