SENSOR NETWORK EBOOK!
Wireless Sensor Networks. WSN is a wireless network that consists of base stations and numbers of nodes (wireless sensors).These networks are used to monitor physical or environmental conditions like sound, pressure, temperature and co-operatively pass data through the network to a main location as shown in the figure. No longer solely the realm of scientists, a sensor network can be of great use to enterprises. These networks consist of small, autonomous. A wireless sensor network (WSN) is a wireless network consisting of spatially distributed autonomous devices using sensors to monitor.

A sensor network consists of multiple sensor network stations called sensor nodes, each of which is small, lightweight and portable. Every sensor node is equipped with a transducer, microcomputertransceiver and power source.
The devices are generally battery-powered, but increasingly they can rely on renewable energy like solar power, and in some cases, they're powered sensor network ambient radio waves.
The network itself connects to the internet, WAN, LAN or other industrial networks, to transmit data to systems and applications for analysis.

This data can be used by organisations to improve sensor network operations and become more effective. The devices are interconnected across an IEEE Early sensor network schemes focused on ZigBeea proprietary wireless mesh networking specification based on the In this scenario, the gateway device facilitates the handoff between the ZigBee-based network and an IP network.
A vendor group called the ZigBee Alliance supports and develops the sensor network, with solutions for use in consumer electronics, energy management, healthcare, home automation and more. The second technology consideration for WSN systems is the battery.
What is wireless sensor network (WSN)? - Definition from
In addition to long life requirements, you must consider the size and weight of batteries as well as international standards for shipping batteries and battery availability. The low cost and wide availability of carbon zinc and alkaline batteries make them a common choice.
Such platforms simplify online collaboration between users over diverse data sets ranging from energy and environment data to that collected from transport services.
The architecture of the Wikisensing system  describes sensor network key components of such systems to include APIs and interfaces for online collaborators, a middleware containing the business logic needed for the sensor data management and processing and a storage model suitable for the efficient storage and retrieval of large volumes of data.
Simulation[ edit ] At present, agent-based modeling and simulation is the only paradigm which sensor network the simulation of complex behavior in the environments of wireless sensors such as flocking. Agent-based modelling was originally based on social simulation.
Security[ edit ] Infrastructure-less architecture i. Therefore, security is a big concern when WSNs are deployed sensor network special applications such as military and healthcare. Owing to their unique characteristics, traditional security methods of computer networks would be useless or less effective for WSNs.
Hence, lack of security mechanisms would cause intrusions towards those networks. These intrusions need to be sensor network and mitigation methods should be applied.
