An Efficient Storage Mechanism to Distribute Disk Load in a VoD Server

In this paper, a storage mechanism is devised to balance the load and to provide immediate service to the clients with a start-up delay of 2ms to 7 ms. The video storage is based on the probability of the clients requesting for the video. Videos with higher probability of being requested are stored and replicated to ensure guaranteed retrieval. Parity generation scheme is employed to provide reliability to non-popular videos. The system is also capable of handling disk failures transparently and thereby providing a reliable service to the clients

Impact of malicious node on secure incentive based advertisement distribution (SIBAD) in VANET

Last decade has seen an increasing demand for vehicle aided data delivery. This data delivery has proven to be beneficial for vehicular communication. The vehicular network provisions safety, warning and infotainment applications. Infotainment applications have attracted drivers and passengers as it provides location based entertainment services, a value add to the traveling experience. These infotainment messages are delivered to the nearby vehicles in the form of advertisements. For every advertisement disseminated to its neighboring vehicle, an incentive is awarded to the forwarder. The incentive based earning foresee a security threat in the form of a malicious node as it hoards the incentives, thus are greedy for earning incentives. The malicious behavior of the insider has an adverse effect on the incentive based advertisement distribution approach. In this paper, we have identified the malicious nodes and analyzed its effect on incentive based earning for drivers in vehicular networks. © 2017 IEEE

Inventiveness towards Environmentally Friendly Solutions for Lignocellulosic Panel Products

In order to move to a greener economy, Panel Industry needs to imply convention development and environmental sustainability. The three important measures to characterize environmentally friendly solutions would comprise of 1) the raw material from sustainable sources, 2) minimal waste generation and 3) process conformance with health and safety standards. In a bid to become more environmentally friendly sustainable, Indian plywood Industries Research and training Institute has carried out research on the suitability of fast growing plantations species for the manufacture of wood composites viz plywood, particle board, medium density fiber board, compregs, laminated veneer lumber. These panel products conform to the requirements of Indian standards. Adhesives from renewable sources such as lignin, tannin, soya, black liquor etc. by replacing phenol in Phenol formaldehyde adhesives. Technology for utilisation of various agro and forest residue such as rice straw, rice husk, wheat straw, casurina, chirpine needle, Coir as raw material to manufacture wood alternatives has been successfully developed by IPIRTI. Low formaldehyde or no formaldehyde emission adhesives for panel products that conform to International standards have led to the development of green technology by minimizing the greenhouse gas emissions. Utilising the industrial waste such as fly ash for the manufacture of wood geopolymer composite would be a new insight for the green construction industry. The Efforts made by IPIRTI in innovating green technology/process have stood the Indian wood based industry in good stead for the benefits of people of the country.Keywords: Green technology, Plantations species, Forest conservation, Environmen

Resourceful Utilisation of Wheat Straw into Value Added Composites

Panel industry is growing at 20.25% largely due to shift in consumer’s preference for Medium Density Fibre board (MDF). Medium-Density Fibreboard Market estimates that the market for MDF reached a value of more than US$ 22 Billion in 2017. The demand for MDF in India is 1600-1800 cbm per day. Since wood raw material is becoming scarce, there is a need to source raw material from other available resources. In India huge quantity of agricultural residue is generated every year. On the other side in the absence of assured returns, farmers find burning is an economic way of managing the agro waste. Burning of straw emits gases like carbon dioxide, methane, carbon monoxide, nitrogen oxide, sulphur oxide which adversely affect human health as well as the environment. Hence instead of burning, use of agro waste for value addition would replace wood in MDF manufacture and thus save valuable trees in forest or outside. Although some breakthroughs have already been made in this direction by previous workers some enhancements in the strength properties have been envisaged through the present investigation. Wheat straw contains 4-6 percentage of Silica. The percentage of silica varies depending on the source of wheat grown. Wheat straw with alkali treatment (0.1 and 0.3%) on the weight of wheat straw was studied for the manufacturing of MDF. MDF panels were made using (10 and 12%) Urea formaldehyde resin, phenol formaldehyde resin and Melamine urea formaldehyde resin and tested as per IS 12406-2003 “Specification for MDF for General Purpose”. The chemical and physical characteristics of alkali treated and untreated wheat straw fibres investigations reveals that the, ash content decreased with the removal of dust and increased alkali treatment. Wheat straw fibre board without alkali treatment can be successfully made using MUF resin and with 0.1% alkali treated using PF resin. The product developed conforms to requirements for MDF as specified in IS-12406-2003 standards for PF and MUF bonded boards. These results indicate that MDF can be made from fibre derived from wheat straw.Keywords: Wheat straw, Medium density fiber board, Forest, Agro waste, Composite

An Integrated Quality-of-Service Model for Video-on-Demand Application.

The tremendous growth of the Internet paradigm has given rise to Quality of Service (QoS) problems in heterogeneous, ubiquitous, distributed real time applications such as video-on-Demand (VoD). The challenging task in VoD applications is to satisfy diverse client requests for discrete videos with restrained resources by invoking versatile QoS schemes. In this paper, a hybrid QoS strategy, which is a combination of batching and recursive patching is implemented in the local server to ensure starvation-free resource management thereby enhancing the throughput. Batching shares network resources efficiently whereas recursive patching is adopted to reduce the time difference between the requests. The suggested algorithm delivers the complete video to the users based on one of the three communication channels: broadcast, multicast and unicast depending on whether the video is very popular, average popular and least popular respectively. The experimental results show that our strategy accomplishes 35% - 40% reduction in terms of blocking ratio and throughput is 10% - 15% higher than the Poon’s strategy, which guarantees that not only the resources are efficiently utilized but also a suitable Quality of Service is provided to each user

Design of Techniques to Enhance the Services for Mobile Video-on-Demand Applications

The current generation of mobile clients have incessant demand for services. Providing Video-on-Demand (VoD) services to these clients require a new paradigm. This paper presents an architecture for Mobile Video-on-Demand. Several schemes that reduces the load on the video server, thereby increasing the number of requests that need to be served is proposed. The Distributed Indexing reduces the storage load on the server and reduces the time to search for a video. The Chaining Technique increases the acceptance of requests and thereby reduces the rejection rate. Two types of hand-offs are defined :Video Server Hand-off and a Client Hand-off. These provide the continuity of services to the mobile clients. The Windowing Scheme which includes Session Management is proposed. This scheme control the flow of segments. All these schemes have been simulated and the results are presente

Threat on incentive based earning in VANET

Intelligent Transport System (ITS) provides several smart transportation solutions. The building block of ITS is Vehicular Ad Hoc Network (VANET). VANET supports and improves the travel experience by leveraging its services through applications. Safety, warning and infotainment are key applications supported by VANET. Infotainment applications are gaining popularity in the Internet based application domain. Advertisements are one of the forms of infotainment messages. Drivers who are vehicle bound play pivotal role in distributing these advertisements. Advertisement distribution promotes additional earnings to the drivers in the form of incentive. For every advertisement sent, the sender earns an incentive. The greed of earning incentives drives the nodes to become malicious and thus, it hoards incentive. These malicious nodes prevent other nodes from earning incentive. Thus, it poses a threat for promoting

EFFICIENT CHANNEL ALLOCATION BASED ON PRIORITY OF THE VIDEO IN VOD SYSTEMS

Today's technology offers easy access to multimedia services through high-speed communication networks. A Video-on-Demand (VoD) service allows customers to connect to an on-line video server and asynchronously watch videos. A Video-on-Demand system is typically implemented by Client-Server architecture. This paper presents a scheme of channel allocation based on priority of the requested video, to increase efficient channel utilization and lower the download time. This allocation scheme shows better performance when compared to conventional way of allocating channels

Determination of Optimal Buffer Allotment for Video-on-Demand Server

The tremendous growth of Internet in popularity especially in the domains of entertainment, education and business had lead to the research on various alternatives to improve the performance of the Video-on-Demand system. The challenge in Video-on-Demand application is to stream uninterrupted, synchronous multimedia data from a video server to a client by utilizing the available resources like bandwidth (channel) and buffer appropriately. The quantity of resource required increases with the increase in the number of clients. As the number of clients increase, the server will reach a limit on the storage capacity. In case of further increase in the load, new servers are to be added which further incurs additional cost. In this context managing the buffer and the channel effectively enables faster retrieval and transfer of multimedia data by providing suitable Quality-of-Service to the client. In this paper, we propose an efficient method to allocate buffer in the local server by using channels in proportion to the popularity of the video. The algorithm reduces start-up latency and reneging probability by utilizing both the channels and buffer effectively thereby the videos are downloaded faster reducing the blocking ratio of the requested video. The results m
