Wireless Sensor Networks have gained popularity due to their real time applications and low-cost nature. These networks provide solutions to scenarios that are critical, complicated and sensitive like military fields, habitat monitoring, and disaster management. The nodes in wireless sensor networks are highly resource constrained. Routing protocols are designed to make efficient utilization of the...
Several Routing Protocols have been proposed and developed in the last few years for Wireless Sensor Networks (WSNs). Since there has been increasing interest in the development of Wireless Sensor Networks to specific applications, it is necessary to discuss routing techniques suitable to the application and segregate the Quality of Service (QOS) parameters specific to the application domain along...
This paper presents the study on the cost analysis for the Video-on-Demand (VoD) system exploiting the advantages of the Peer-to-Peer (P2P) architecture. Our objective is to tackle the problems in analyzing cost and to come up with efficient cost analysis model (CCAM) thereby enhancing the revenue to the system. We adopt a partially decentralized P2P architecture with a cluster based approach to find...
Ad hoc networks are collection of mobile nodes which communicate using wireless media without any fixed infrastructure. Each mobile host acts both as a network router and an end point as packets are forwarded over multiple hops. Node mobility being the distinguishing feature of the mobile ad hoc network, makes routing an important challenge. Hence, Quality of Service (QoS) is not easily achieved in...
Research in wireless sensor networks has become an extensive explorative area during the last few years. In this paper we emphasize the need for repositioning of the consolidating and advancing node, (CAN : Principal Node) to improve network lifetime in terms of energy and other QoS parameters such as latency and throughput. We also address issues related to its repositioning such as the time and...
The phenomenal growth in the distributed multimedia applications has accelerated the popularity of Video-on-Demand (VoD) system. The vital task of multimedia applications is to satisfy diverse client's request for distinct video with confined resources by using assorted Quality-of-Service (QoS) procedures. In this paper a fusion of data sharing techniques like batching and recursive patching is applied...
