Essay about Wireless Sensor Network (WSN)

Wireless Sensor Networks (WSN) are made up of tiny sensing devices; capable of sensing some changes of incident/parameters and communicating with other devices, over a specific area. Mainly used for tracking, surveillance and environmental monitoring. These devices make it possible to be used in a system such as Home Automation and Security. Our purpose is to make our Home secure from any attacks physically and to the sensor network. Securing our Home starts from the outside, setting up a perimeter around house sensing intrusion and alerting the home owner. Allowing only predetermined users to enter the home. From the inside you can monitor for fires, leak, humidity or smoke, which the system will promptly report this to the owner as well as alert the proper authorities. Making most of the home voice controlled only recognized by the owner’s voice can add another layer of security.

Parking is an important part of the transportation system. It is an efficient means of storing vehicles while they aren’t in use, and it causes little disruption to the neighboring roadways. Additionally, since parking is the terminal or destination for a trip, the availability of parking space can affect the attractiveness of destinations as well as transportation modes. The attractiveness of a destination is reduced if there is a delay or difficulty in parking. The use of transit systems is increased in areas where parking is scarce. To be efficient, the transportation system must include adequate parking facilities at all places that attract trips.

1. Wireless sensor networks are used in those hostile environments where wired networks can't be deployed. For example in a forest, wireless sensor nodes are dropped from the air because going down there and deploying a wired setup is not possible.

Automated guided vehicle system uses FROG (Free ranging on grid) technology (it contains map of that area).

Those factors were the residents, commuters, non-work trips, and commercial vehicles. The success of San Francisco’s city traffic management is directly dependent on parking planning, the stability of its businesses, and the enjoyment level of its visitors and residents. On the contrary, poor parking planning can be just the opposite, with traffic congestion, competition between urban businesses and suburban organization can become affected, inner city residents becoming dissatisfied and discouraged with continually having to find parking spaces when they return

Although popular, it have gather its fair share of complaints. The strongest of the complaints is the lack of a legitimate space to park vehicles. The usual solution for

The following report is prepared by Team 9 for Geoff’s Transportation and Parking Services (GTPS) for their new product Sure-Park system. The Sure-Park system state-of-the art garage parking system whose goals are:

Rutgers University students are building a computer generated parking system that will track down how many parking spaces are full, occupied, and available. The new parking system allows customers to register their vehicles by inputting their personal information such as their e-mail address.

In recent years, parking a automobile has become a heavy downside in giant cities with increasing rate of personal vehicles. With the rising downside of parking cars, the normal parking system that doesn't offer any info regarding out there parking areas wouldn't be able to handle the matter effectively. the everyday parking area system would solely be able to offer information of accessible parking locations or another system would need human resources to see and supply information regarding the situation of the available parking locations. These varieties of parking systems would solely offer marginal information on the out there parking locations and wouldn't be able to handle the parking problems effectively. in and of itself these systems

A lot of experts suggest more express pricing of parking facilities, and for a multiply of reasons many cities, campuses and commercial buildings are growing anywhere and as soon as parking is priced. Numerous existing trends raise the rationalization for pricing parking, as well as increased urbanization and land costs, increased worry about vehicle traffic external costs (congestion, accidents, pollution, sprawl), and enhanced pricing technologies. However, unpriced parking is well recognized, so parking pricing accomplishment requires overcoming various political, institutional and technical obstacles. Care is essential to be in touch the benefits and address potential problems. Parking pricing is just one of some parking administration

The shortage of parking space in America 's college is becoming an extremely concerned problem. This parking issue is highly impacting students ' campus life. Many college students, even faculties, and visitors find that it is hard to park on campus, especially at some busy times. The situation is that students would encounter parking is so scarce, and they have to wait for somebody to leave and take their spots. Otherwise, students have to waste their time driving around and around the parking lot. Even though students pay for their parking permit, they are not guaranteed for a parking space. The shortage of parking space causes a lot of trouble for students. Because of there is no parking space, students will get late for class, which could lead their grade to get lower. In other cases, students will have to park in a very faraway place, which they are forced to prepare more time to park and it takes them too long to walk to their classrooms. It also increases the risk and danger walking and driving in the parking lot. Drivers need to drive while they are searching, which could be very dangerous. To solve the shortage of parking spaces, colleges are suggested to build a parking structure, open more parking lot at busy times, manage the class time to relieve the busy period and provide more pubic transportation and bicycle services to the students.

Woody EPPS Car Finder is offering a RFDI device that assists in locating a vehicle quickly within public parking areas, which tend to be overcrowded. The technology will locate vehicles parked in large parking areas and structures, directly the owner to its location. In this case the RFID uses short range radio frequencies to track the vehicle within a specific range using a hand held battery powered receiver. The target demographics are organizations linked to public parking, health insurance for senior and elderly individuals and the general population globally.

For that reason, it is vital to consider network coverage and energy consumption in the design of WSN layouts.

In order to cope up with the growing problem of traffic congestion several means and methods have been implemented.For reducing this problem,an efficient method for traffic monitoring can be implemented by providing the availability of the parking spaces in advance. Since there exist no such system we intend to develop one using sensors and RFIDs.In proposed system, we consider car park equipped with sensors(IR) which checks for the availability of parking slots and updates the information periodically.This updated information is provided to the user via an android application. Using this application user gets directed towards the parking slot by using the shortest path algorithm(Dijikstra 's). Also to avoid traffic congestion due to parking charges, car is associated with a unique RFID tag for the wallet parking.

This system concentrates more on optimizing and improving the payment methods for a parking system. It uses the technology of smart cards, mobile communications, and also RFIDs. The objective of this system is to save more time and make it more convenient when users make their payment. There are a few problems with the current parking traditional payment such as the coin operated meter. Coin operator equipments are expensive and it needs frequent maintenance as it is always visible for vandalism. It is also costly as it needs human resource for collecting and enforcing payment [1].
