Well-organized big data get together in the densely distributed sensor networks is, therefore, a challenging research area. One of the most effective solutions to address this challenge is to utilize the sink node’s mobility to facilitate the data gathering. While this technique can reduce energy consumption of the sensor nodes, the use of mobile sink presents additional Challenges such as determining the sink node’s trajectory and cluster formation prior to data collection. In this paper, we propose a new mobile sink routing and data gathering method through network clustering based on modified ExpectationMaximization (EM) technique. In addition, we derive an optimal number of clusters to minimize the energy consumption. The effectiveness of our proposal is verified through numerical results.
Routing in Wireless Sensor Networks has to take into account the limited battery resources of the nodes. Sensor nodes can also be powered by other energy sources like solar energy. This paper provides a review of Environment monitoring using Wireless Sensor Networks. The issues related to environment sensor networks is highlighted. The real time applications in environment monitoring is presented with emphasis on energy conservation. Furthermore in this paper we address the problem of scavenging energy using solar powered devices.
Mobile Ad hoc Network (MANETs) is an infrastructure – less network which is created by deploying the mobile nodes carrying wireless devices, able to route the data through multi hop fashion. MANETs uses distributed routing approach. In this paper, analysis of different classification of routing protocols such as: Reactive (AODV, DSR) Proactive (DSDV) and Hybrid protocols ZRP (Zone Routing Protocols) has been done using NS2 simulator. The above work analysis has been done on the following QoS parameters such as: Packet Delivery Ratio, Average Throughput, Routing Overhead and Average Delay

Network coding has been recently applied to wireless networks to increase throughput. Back-pressure type algorithms based on the algorithmby Tassiulas and Ephremides have recently receivedmuch attention for jointly routing and scheduling over multi-hopwireless networks. we explore the performance of backpressure routing and scheduling for TCP flows over wireless networks. TCP and backpressure are not compatible due to a mismatch between the congestion control mechanism of TCP and the queue size based routing and scheduling of the backpressure framework. We decouple the routing and scheduling components of the algorithm by designing a probabilistic routing table that is used to route packets to per-destination queues. The scheduling decisions in the case of wireless networks are made using counters called shadow queues.
The present study analyses the combined, individual, and incremental value relevance of accounting information produced by firms listed on the S&P BSE-500 for FY-2006 to FY-2010, and changes therein over a period of time. Results provide sufficient evidence that accounting information is value relevant for BSE-listed firms. The combined value relevance of accounting information represented by earnings per share and book value per share has declined while there have been insignificant changes in the incremental value relevance of accounting information.

Dubai has been choosen as an intercontinental property and assets hotspot, equipped with great archaeologist developments and thus wannabe ventures going up up apparently with their rapidly. Together with the segment in spite of everything juvenile and furthermore necessitate excess produce, the amount of time will be perfect designed for tourists to acquire this particular strong, wonderful metro area.Present in April June 2006 the very Freehold Guidelines became surpassed encouraging tourists sometimes 97 summer leasehold or perhaps even perpetual usage regarding ground inside of runs destinations. Perpetual or perhaps even leasehold permits the unusual individual numberous perk. Homeowners may well offer for sale in addition to rent out their house in Dubai especially if they so desire.
