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.

We like to build smart phone applications for cellular operators and handset manufacturers, game developers, as well as ring tone developers. We develop solutions using J2ME, Brew, iPhone, Palm Pre, Windows Mobile, Flashlite and Symbian platforms, that allow rapid deployment and sophisticated user functionality. We are one of the few mobile software development companies that can work across all major mobile platforms available today.
Clustering technique is the basic technique used in the wireless sensor network to enhance the lifetime of a sensor network by mitigating energy consumption and provide efficiency, scalability, and security. Formerly sensor nodes are considered to be homogeneous in which each node has the same processing capacity, energy and functionality, but to prolong network lifetime researches has been evolved to infuse heterogeneity in wireless sensor network such as to provide different energy level to some nodes. In this paper, we present a survey on basic clustering techniques for Heterogeneous wireless sensor networks.
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
Gray level Slicing is to highlight a specific range of gray values. Power Adaptation methods are presented for gray level slicing approaches. Power Adaptation methods aims in optimization of the resulting bit error rate by gray level slicing without preserving background and gray level slicing with background. This paper gives us an achievable increase in the proposed method rather than the conventional method with a better quality and the bit error rate is also optimized in proposed method rather than the former method with acceptable quality.
Warning! This prevalent system of insurance is perforated with exclusions, which a lot of travelers have no idea about. One must not ever miscalculate, thinking that one policy is like another. Travelers have been cautioned they might not be covered by their insurance when requesting for holiday incidents as they are under the influence of alcohol or non-prescription drugs. Also, avoid insurance fraud tips while traveling Jakarta Indonesia.
With the numerous other businesses in Jakarta Indonesia, construction companies are achieving the status each day. It transpires due to its remarkable benefits that assist others to generate big return from it. Construction business like Axis Capital Group, Singapore is the finest program to gross big income and form a sturdy place in the market. At present, coming as a new comer in this line of work and aspire to manage your business profitably, thenceforth it is significant to buy necessary heavy equipment for your site. There are a lot of kinds of heavy machinery that can be advantageous in construction site. On the other hand, there are some features that you must recognize accurately prior to buying the equipment. The most significant point that demands your focus is the specification of the equipment. Every single machine comes with diverse specifications that you must become skilled at so that you can acquit yourself well with your requirement.
In today's digital environment with all the broadband connectivity and smart devices, the line blurring between the real and virtual, many brands are making an effort to create virtually real experiences to reach out to their consumers.
