Speech recognition is a vast research field for researchers in modern era. Earlier, the human language was processed by the computer system for speech recognition. Thus, the main objective is to develop recognition system which improves human to human communication by enabling human-machine communication by processing of text or speech. Various applications(More)
A wireless sensor network (WSN) composed of a enormous quantity of multifunctional wireless sensor nodes. General Self-Organized Tree-Based Energy-Balance Routing Protocol (GSTEB) is a protocol which is proposed for wireless sensor networks and is used to reduce the entire energy utilization and to balance the wireless sensor networks load. Although GSTEB(More)
This research presents the multi –modal biometric system for iris and fingerprint This paper presents the Feature level fusion using wavelet for combining two unimodal biometric system. Gabor transform is used for feature extraction and wavelet transformation for fusion of iris and fingerprint. The system applied artificial neural network technique for(More)
Vehicular ad hoc network (VANET) is a self organized network which connects vehicles on the road with each other and with road side units (RSU) to improve and maintain the safety on road and to manage traffic. To provide communication among vehicles, routing protocols are used. In this paper, we examine the working of some routing protocols in VANET(More)
Now-a-days Internet has become the common media of communication. Many group communication application such as pay-per-view, stock quote distribution, voiceand video-conferencing, white-boards, distributed simulations, and replicated servers of all types, etc can easily be conducted on the Internet. For conducting such applications, group key is often(More)
A mobile ad hoc network (MANETs) has become necessity in today's world. It has significant advantage when it is compared to the structured based network. Due to high demand of MANET, its performance is considered prior during implementation. Performance of MANET depends upon life time of network which further depends on various parameters such as, energy,(More)
Despite the fact that sharing pictures and recordings are well known, messages and blog articles still remain as an essential part to express feelings. Contrasted with exploration of feeling identification in multimodal fields, sentiment discovery from text is still unexplored and requires more changes to be amassed as useful applications. That is why need(More)
Secure and efficient group communication in ad hoc networks is a very challenging task. Due to resource constraints in ad hoc networks, the group key agreement protocols must be efficient in various parameters such as number of rounds, number of messages exchanged, exponential computation performed etc. This paper presents various group key agreement(More)
Data aggregation at the bottom station with entity nodes act as the root for overflow of the information which consequences in peak power utilization. To diminish this dilemma a new data aggregation technique has been proposed called ERA which has improved the performance of the WSNs by using the group based data aggregation but even then it has some(More)
