In recent days, the big data opinion mining is considered as an important research area because, the size of the user reviews increase in petabytes. Opinion classification is the process of identifying the positive, negative and neutral opinion from the text. The traditional data mining software tools find it difficult to manage the reviews because of its size. Hence, to provide an efficient big data...
Vehicular Ad Hoc Networks (VANETs) is an essential and emerging area of research in the field of Ad Hoc Networks. The main objective of deploying VANET is to improve the road safety and reduce the number of accidents. In VANET, routing is a difficult task because of the high mobility of nodes, which causes rapid changes of topology and to deliver a packet within a minimum period of time. Existing...
Today's world is flooded with unstructured information. Big data is not just a description of raw volume but it has to real issue of usability. The major part of information retrieval is giant experience in big data. The real challenge is identifying or developing most cost effective and reliable methods for extracting value from all the terabytes and petabytes of data now available. That's where...
A Mobile Ad-Hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without using any centralized access point or administration. MANET protocols have to face high challenges due to dynamically changing topologies, low transmission power and asymmetric links of network. An attempt has been made to compare the performance of two On-demand reactive routing protocols...
Network Congestion is a key problem in today's Internet. TCP is used as a Transport Protocol for most of the applications on the Internet and is also responsible for adjusting to network congestion dynamically. TCPs congestion control mechanism is insufficient in a wireless environment because packet loss does not always mean congestion, but can be due to the sudden drop in channel quality. The throttling...
Internet congestion occurs when the aggregate demand for a resource (e.g., link bandwidth) exceeds the available capacity of the resource. TCP is used as a Transport Protocol for most of the applications on the Internet and is also responsible for adjusting to network congestion dynamically. TCPs congestion control mechanism is insufficient in a wireless environment because packet loss does not always...
