Mobile Ad-hoc network is a collection of two or more node equipped with low power device for data transmission. Many Proactive based Power Aware Routing (PAR) protocol was implemented by many researchers. An optimized power reactive routing protocol describes the concepts of cognitive function and AODV protocol. It ensures that data packet is transferred in(More)
H.264 video coding standard supports a broad range of application and providing its security is an important research topic. In this work, a video encryption algorithm for H.264 is proposed, which combines permutation code algorithm with dynamic keys. This work aims at providing more security for H.264 video using dynamic keys and permutation code(More)
Handwritten document recognition is an area of pattern recognition that has been showing impressive performance in the machine printed text. Handwritten document recognition is an intricate task to various writing styles of individual person. The system first identifies the contour in a handwritten document for segmentation and features are extracted from(More)
4G wireless communication expects to integrate different radio access technologies together to meet wide expectation from users and to support mobility. Call Admission Control (CAC) plays important role in such heterogeneous environment to effectively utilize network resources and to meet user QoS. This paper proposes IP Multimedia Subsystem (IMS) based(More)
Group Communication has become important in Mobile Adhoc Network (MANET). But because of its dynamic topology it is difficult to implement group communication in MANET. In order to implement group communication, Efficient Geographic Multicasting Protocol (EGMP) came into existence, the efficiency and scalability of the protocol was already tested using(More)
Since the past few years organizations have increasingly realized the value of social media in positioning, propagating and marketing the product/service and organization itself. Today every organization be it small or big has realized the essence of creating a space in the World Wide Web. Social Media through its multifaceted platforms has enabled the(More)
Heterogeneous cellular network (HCN) consists of macro, pico and femto cells within the same geographical area. This network utilizes available spectrum efficiently using frequency reuse technique. Due to frequency reuse the HCN network suffers from inter-cellular interference. To reduce interference and to maintain QoS of pico and femto cell users, Time(More)
4G communications expects to integrate different radio access networks together to meet wide expectation from users and to support mobility. The different radio networks such as Universal Mobile Telecommunication Systems (UMTS), Worldwide interoperability for Microwave Access (WiMAX), Wireless Local Area Network (WLAN), etc. are collocated in same(More)
