The cognitive radio network (CRN) is an emerging technology where communication among secondary users (SUs) takes place in an opportunistic manner. Since, a backbone eases the routing, reduces communication overhead, and efficiently handles the dynamic changes in the network. Therefore, we intend to propose a backbone formation algorithm in CRN. However, finding optimal backbone is equivalent to find...
As the technology advances more and more information are getting accumulated in the form of web sites in the internet. Web mining is a technique of extracting information from the internet which helps the users in finding quality pages. The main problem is that search engines are not capable enough to provide the relevant data. They fail to index all the information available on the web. Web mining...
Web has grown enormously and is still growing rapidly day by day. With this huge amount of information in the web it has become difficult for the search engines to retrieve the required and relevant information efficiently. Web mining techniques, using different approaches, have contributed a lot in providing the relevant information to the user query. This paper introduces a new method for prioritizing...
Software testing approaches are mainly divided into three types i.e. code based testing, specification based testing and model based testing. In model based testing, the testing can be started from the design process at the beginning phase. So, early detection of faults can be achieved by using this approach. An approach for the generation of test cases from UML (Unified Modelling Language) activity...
In distributed system there is a need for allocating processes to different sites (space sharing) followed by scheduling of the processes over time (time sharing). By carefully distributing and scheduling processes in distributed system, several performance metrics can be improved such as total execution time would be minimized, processor utilization could be maximized and balancing of load distribution...
