Sensor network technology is considered as one of the key technologies for the 21st century. Wireless sensor networks have emerged as an important area for research and development. Their impact is predicted to be far-reaching, and they are attracting a great interest in many applications from remote monitoring of environment, habitat, agriculture, military applications, health care, automation, dangerous areas, and disaster prone zones, among many others. Through advances in sensor, networking, semiconductor and energy storage technologies, future Wireless Sensor Networks will combine to form the nervous system of the Internet of Things. In these networks, the nodes are typically operated by battery power, making energy consumption a very important fact to increase the network lifetime. The large number of sensor nodes involved in such networks and the need to operate over a long period of time require careful management of the energy resources. The goal of this project is to design and implement a wireless sensor network, using an Arduino board and a Xbee module, to measure a single (or multiple) variable such as temperature, ensuring communication between nodes, as well as designing a power stage for the nodes. The document will first make a review of current wireless technologies, then it will study the available hardware and software to implement and finally it will propose and develop a solution to achieve the mentioned objective.

What You Will Learn Interact with XBee boards using the XCTU program on Windows, OS X, or Linux Make your Arduino boards communicate wirelessly, using XBee modules in the advanced API mode Centrally collect and store measured sensor data, in the cloud or your own database Connect the coordinator Arduino to the Internet and send data to web services Control your environment automatically, based on sensor input from your network Interact with off-the-shelf ZigBee Home Automation devices Make your devices battery-powered and let them sleep to get months or even years of battery life In Detail Arduino has been established as the de facto standard microcontroller programming platform, being used for one-off do-it-yourself projects as well as prototypes for actual products. By providing a myriad of libraries, the Arduino community has made it very easy to interact with pretty much any piece of hardware out there. XBee offers a great range of low-power wireless solutions that are easy to work with, by taking all of the complexity of wireless (mesh) networking out of your hands and letting you focus on what to send without worrying about the how. Building wireless sensor networks is cost-effective as well as efficient as it will be done with Arduino support. The book starts with a brief introduction to various wireless protocols, concepts, and the XBee hardware that enables their use. Then the book expands to explain the Arduino boards to you, letting them read and send sensor data, collect that data centrally, and then even control your home from the Internet. Moving further more advanced topics such as interacting through the standard Zigbee Home Automation protocol, or making your application power-efficient are covered. By the end of the book, you will have all the tools needed to build complete, real-world solutions. Style and approach A hands-on guide, featuring a single home automation project that can be built as described or with endless variations. Every step is illustrated with complete examples and screenshots, allowing you to build the examples swiftly.

Since the time of their introduction, Wireless Sensor Networks (WSN) have been catching the interest of researchers. WSN have a wide range of applications, some even involving sensitive and secret information, thereby raising security concerns. Nevertheless, WSN have some constraints like limited memory, energy and computational capability, which pose an obstacle for the addition of proper security in sensor nodes. This thesis introduces a new rekeying design for WSN security framework whose implementation would dispense effective security in the sensor nodes. This proposed security framework is endowed with the capacity to address security issues, such as message integrity, confidentiality, authenticity and freshness based on symmetric key cryptography. In addition, this design does not allow the storage of any key except the initial master key in the sensor nodes prior to network deployment. This thesis also investigates reconfigurable sensor nodes in terms of execution time, memory, power consumption, and cost while running the security framework. Finally, the findings of this thesis are compared with previous studies conducted in this interesting field.
