Abstract

Infrastructure-less and Self-organized networks among vehicles are known as Vehicular ad hoc networks (VANETs). Designing efficient routing protocols for rapid topology changing environment is a major concern. Optimized Link State Routing protocol (OLSR) - link state, table driven proactive protocol uses control messages to identify the link state information everywhere in the network. Being a Proactive protocol routes to all destinations within the networks are known and maintained before use, which leads to uncertainty for the Data transmission. Due to this limitation in OLSR it is necessary to optimize the routing. In this study, to minimize the Uncertainty in OLSR routing due to the frequent change in the topology, Rough Set Theory (RST) is used. Our proposal is further validated by simulation.

Abstract

More effective and friendly methods for Human Computer Interaction (HCI) are being developed due to the pervasiveness of new information technology and media, which do not need any traditional interacting devices such as keyboards, mice, and displays. The face processing research based on the premise that information about a user’s identity, state, and intent can be extracted from images, and that computers can then react accordingly. Gesture recognition aims at creating a system to convey information or for device control which can be identified by specific human gestures. Real-time vision-based hand gesture recognition is considered to be more and more feasible for HCI with the help of latest advances in the field of computer vision and pattern recognition. This survey papers deals with discussion of various techniques, methods and algorithms related to the gesture recognition and sheds information about Face detection. One of the natural way of communications is to use hand gesture which combines the emotions of human to real world. Hand gesture recognition has the various advantages of able to communicate with the Technology through basic sign language. The gesture will able to reduce the use of most prominent hardware devices which are used to control the activities of computer.
