A wireless sensor network is a wireless network consisting of spatially distributed autonomous devices using sensors.They have the ability to monitor the physical as well as the environmental conditions.It is being widely adopted as a promising solution to numerous numbers of challenges which are being faced today. Sensor nodes, also known as motes, not only have limited amount of storage as well as processing capability which is a severe problem but also another constraint is the limited amount of energy of these sensor nodes. Dissipation of the nodes energy poses very critical issueas the lifetime of the node is limited by its battery capacity inwireless sensor network.

Even if a large number of low-power sensor nodes aredeveloped, each deployed nodes have limited information processing capability and also have limited storage capability.Thus they have relatively short distance for communication.But on the other hand, the sink node is free from such shortcomings. As compared to sensor nodes, the sink nodes have larger capacity, a power supply that can be sustained for much longer time, a longer central processing unit (CPU) and also larger memory devices. Also, a sink node can connect itself to another sink node, depending on the need of the user's, or it can also connect itself to a wired connection, such as the internet, which has infrastructure …show more content…
First, considering the high density of nodes, the routing protocols should route data over long distances, irrespective of the network structure and size of the network. Some of the active nodes may fail during network operations due to depletion of the energy of sensor nodes or hardware breakdowns or various environmental factors, but these issues need not interrupt the normal operation of the network. Also as the sensor nodes have limited amount of power supply, limited processing capability, with limited memory and available bandwidth, need arises for efficient routing and data dissemination such that the network resources are utilized effectively. Furthermore, as the performance demands of wireless sensor networks are wholly application dependent, routing algorithms should satisfy the QoS demands of the application for which the network is being deployed. For example, challenges in designing the routing algorithms for environment monitoring will be different from issues that should be considered for target tracking or health care monitoring. Based on the differences between traditional wireless networks and the wireless sensor networks, various routing protocols have been proposed over the past few years, to address the challenges faced while routing the data packets in the wireless

This paper propose an adequate approach of charging and recharging Smartphone batteries by Converting Power to Data and transmitted through a Wi-Fi ( Radio Wave) connectivity, also interconnect with Power consumption application that will automate and asynchrous power consumptions . The outcome of this research is recharge Smartphone batteries whenever Wi-Fi connectivity is available and accessible. And not to worry
As the technology developing, everything becomes computable. And when people realizing the importance of the Internet of Things, more and more data is collected. Analyzing such amount of data becomes a big challenge for modern people. As a very important component of our life, internet becomes indispensable. Data sharing between multiple users becomes more popular. It seems our life will stop if without the internet. The user devices becomes much lighter, most computing and data storage are separated with remote operations. Distributed system becomes more and more useful for our life.
The rapid progress of embedded MEMS (micro-sensing technologies) and wireless communication has made wireless sensor networks possible. Such an environment may have many wireless nodes which are inexpensive; each node is capable of collecting, storing and processing environmental data, and communicating with neighboring nodes. These sensors are connected with wires in the past but tod...
This project is motivated by the application that can be utilized using a wireless mesh network and their advantages. Various technology companies show their interest in wireless mesh network by manufacturing several of the product based on this technology. Even though this technology still in early stage, increasing interest of the industry in this topic triggering more interest to researcher around the world to know more about this topic. Below are the main principle why wireless mesh network is one of the network topology that been focusing on:

Wireless local area networks (WLANs) have the potential to improve the flexibility, productivity, and the quality of work life of an enterprise (Sage Research Staff, 2001). Berean Institute is a typical two year college with about a staff of sixty eight employees and 250 students per semester. Berean teaches cosmetology, barbering and the latest software and hardware technology, which is located in Philadelphia, Pennsylvania. Berean currently has two locations in the Philadelphia area and using a Local Area Network (LAN).
A typical home wireless network consists of an access point (AP), several personal computers, and increasingly, personal devices such as tablets or cellphones. Today, a home wireless network is primarily used to provide access to a wired Internet connection via communication that occurs to and from an AP. Future home wireless networks are expected to feature different types of traffic (such as multimedia streaming) which may require efficient communication between any two devices in the home (Papagiannaki, Yarvis, & Conner, 2006).
The world has gone through a lot of changed as time passes by. With advancements in the technological field people are can communicate with ones from around the world without having to even lift a finger. To make things more efficient and more cost saving industries have made technology wireless. Wireless technology gives people the chance to get up from their stationary computer, or cord phone and able to freely move without restrictions. The IT, or Information Technology has become a standard and very critical part of today’s society. Wireless technology came from the basic just cellular usage to sensors in the medical field. Wires are now a thing of the past in today’s world with forever revitalizing technology.

In this task I am going to write a report on the effects of electronic communication on me, my family and the society. I will extend my report by giving a clear explanation that includes society in general, i.e. people and situations outside of my normal experience (i.e. business). I will also include in this report the people that do not have access to electronic communication.
At SRM, I was introduced to the true expanse of computer science. Subjects such as Computer Networks, Algorithms, Probability theory, Principles of programming languages and Data Structures piqued my interest as they allowed me to explore my analytical, logical and creative attributes. Computer Networks, in particular, taught me the importance of sharing of information – the first and foremost thing that we care about. Gradually, my tryst with computer networks become intense as I began to explore more and more about their significance and applications in various facets of life: education, social media, research, entertainment, etc. This fascination and exploration led me to do my final year project on mobile ad hoc networks under the guidance of Professor Velmurugan P. It presents a lifetime prediction routing algorithm that maximizes the network lifetime of MANETS by selecting the least dynamic route with long lifetime for maintaining the uninterrupted data flow. Later on, the pap...
The Global Positioning System, more commonly called the GPS is a satellite based system that provides navigation for almost everything from cell phones to automobiles. This wonderful technology is very vital in today’s economy because of its prominence in banking, financial markets, power grids, farming, construction and so much more. It also protects human life by preventing accidents, helping in search and rescue missions and is critical to nearly every facet of military operations. There are three segments that make up the global positioning system: the space segment, the control segment and the user segment. The segment we are familiar with is the user segment. The user segment is what receives GPS signals, determines the distance between a satellite and a receiver and solves the navigation equations, all in order to obtain the coordinates of a specific place. The space segment consists of 31 satellites but there is an availability of at least 24 satellites that are approximately 6 000-12 000 miles above the earth.
