This document presents a proposed system for reliable content video streaming services for peer-to-peer (P2P) networks using Network Coding Equivalent Content Distribution (NCECD). The existing systems have drawbacks like more buffering time, time spent optimizing large file distribution, and long wait times for videos to load. The proposed system aims to provide interactive video-on-demand services in P2P networks with reduced delay, scalability, flexibility and low latency. It divides videos into segments stored across peer local storage in a distributed manner, allowing clients to pick servers without additional search. This supports dynamic peer networks while solving server load balancing and reducing loading/buffering times.

Chaining Algorithm and Protocol for Peer-to-Peer Streaming Video on Demand Sy...
As the various architectures and protocol have been implemented a true VoD system has great demand in the global users. The traditional VoD system does not provide the needs and demands of the global users. The major problem in the traditional VoD system is serving of video stream among clients is duplicated and streamed to the different clients, which consumes more server bandwidth and the client uplink bandwidth is not utilized and the performance of the system degrades. Our objective in this paper is to send one server stream sufficient to serve the many clients without duplicating the server stream. Hence we have proposed a protocol and algorithm that chains the proxy servers and subscribed clients utilize client’s uplink bandwidth such that the load on the server is reduced. We have also proved that less rejection ratio of the clients and better utilization of the buffer and bandwidth for the entire VoD system.
Optimal Streaming Protocol for VoD Using Clients' Residual Bandwidth
A true VoD system has tremendous demand in the
market. The existing VoD system does not cater the needs
and demands of the market. The major problem in the VoD
system is serving of clients with expected QoS is difficult. In
this paper, we proposed a protocol and algorithm that
chains the proxy servers and subscribed clients. Our
objective is to send one server stream and this stream should
be served to N asynchronous clients. The server bandwidth
is scarcity and on the client uplink bandwidth is
underutilized. In this protocol, we are using client’s residual
bandwidth such that the load on the server bandwidth is
reduced. We have proved that optimal utilization of the
buffer and bandwidth for the entire VoD system and also
less rejection ratio of the clients.

This paper proposes a new Hybrid Adaptive Mobile Streaming (HAMS) method for efficient video streaming on mobile devices using cloud services. HAMS uses Scalable Video Coding (SVC) to encode video files into base and enhancement layers. It first progressively downloads base layers, then adaptively streams enhancement layers to avoid video freezing while providing high video quality. An experiment compares HAMS to existing methods and finds HAMS achieves zero video freezes for up to three users, shorter freeze times, and better average video quality. The paper concludes HAMS is an effective method for mobile video streaming without freezing issues or reduced quality.

Video on Demand (VOD) system over the wireless mobile network is a system that provides video services to mobile clients. The main problem with these systems is the high service delay where the mobile clients have to wait to view their favorite movie. The importance of this paper is based on finding a solution on how to reduce the delay time in the VOD system. This paper introduces a novel caching mechanism named
Proxy Server Cache mechanism to tackle the issue of service delay. This delay happens when the broadcasting phase that is related to the first segment is missed by a client from the current broadcasting channels. In this mechanism, the video’s first segment is stored on a server of a stationary proxy type. The
delayed clients will directly acquire the first segment from the proxy server instead of waiting for the following broadcasting channel pertaining to the first segment. The proposed scheme ensuresobtaining the first segment from mobile clients when they arrive. Additionally, the performance of the proposed scheme is validated by applying the VOD system, which can involve the balancing mechanism to retain particular requests through to the local proxy server to provide a fair dissemination for these requests. The obtained result confirms that the proposed scheme reduces the time delay of the system in comparison with the best existing schemes. The results of the average time delay in the Proxy-Cache scheme is 179.2505
milliseconds when 10 clients arrive each minute (Client/minute), the average time delay is 140 milliseconds when the video lengths are 30, 60 and 90. Meanwhile, the failure probability for obtaining the first segment of the video remains zero when the number of arrived requests is set to2, 4, 6, 8 and 10.

Video Streaming Compression for Wireless Multimedia Sensor Networks
This document discusses video streaming compression for wireless multimedia sensor networks. It proposes a cross-layer system that jointly controls the video encoding rate, transmission rate, and uses an adaptive parity scheme. At the application layer, video is compressed and divided into packets. These packets are encoded at the transport layer and forwarded through the network layer. An active buffer management scheme and adaptive parity check are used to maximize received video quality over lossy wireless links. Simulation results show the proposed techniques can achieve higher throughput by resequencing dropped packets. The goal is to design an efficient system for wireless transmission of compressed video that optimizes video quality.

High Definition (HD) devices requires HD-videos for the effective uses of HD devices. However, it consists of some issues such as high storage capacity, limited battery power of high definition devices, long encoding time, and high computational complexity when it comes to the transmission, broadcasting and internet traffic. Many existing techniques consists these above-mentioned issues. Therefore, there is a need of an efficient technique, which reduces unnecessary amount of space, provides high compression rate and requires low bandwidth spectrum. Therefore, in the paper we have introduced an efficient video compression technique as modified HEVC coding based on saliency features to counter these existing drawbacks. We highlight first, on extracting features on the raw data and then compressed it largely. This technique makes our model powerful and provides effective performance in terms of compression. Our experiment results proves that our model provide better efficiency in terms of average PSNR, MSE and bitrate. Our experimental results outperforms all the existing techniques in terms of saliency map detection, AUC, NSS, KLD and JSD. The average AUC, NSS and KLD value by our proposed method are 0.846, 1.702 and 0.532 respectively which is very high compare to other existing technique.
Project Paper
This document discusses methods for distributing computationally difficult video encoding work across multiple computers to reduce the total encoding time. It presents an application developed that splits video files into chunks, distributes the chunks to client computers to be encoded in parallel, then recombines the encoded chunks. Testing showed encoding time decreased significantly as more computers were added, with up to a 90% reduction in time when using 12 computers compared to one. However, diminishing returns were observed from additional computers. Room for improvement includes using a peer-to-peer model and supporting additional formats/operating systems.
P2P Video-On-Demand Systems
This document proposes a new retrieval strategy called CoRe for peer-to-peer video-on-demand systems. CoRe aims to minimize response time and maximize throughput. It does this by selecting multiple serving peers to collaboratively service each request based on factors like distance and available resources. The document outlines limitations of existing strategies, describes the CoRe algorithm in detail, and presents experimental results showing CoRe performs better than the Least Load First algorithm, especially under heavy workloads.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
