Wireless Sensor Networks (WSNs) are new category of wireless networks that aregaining importance in large number in civilian and military applications. WSN is adistributed and autonomous sensor device used for monitoring physical or environmentalconditions. Sensor nodes are part of WSNs and are tiny in size. They are connected and communicate with each other to exchangedata and information. These nodes are capable of sensing temperature, humidity,pollution level in environment, atmospheric pressure and transfer these informationto a base station (BS) which is also termed as sink. Some of the applications includeweather monitoring, movement of vehicles in highways, movement of wild animals inforest, battlefield surveillance and industrial applications. Nodes in the networkcommunicate among themselves through wireless medium and the same medium isused to transfer data from sensor nodes to sink. Sensors are equipped with batteryas source of energy which gets drained quickly and in many situations they are notreplaceable. Therefore, there is a need to design protocols for different layers whichare energy aware. The objective of this chapter is to highlight the techniques, issues,challenges and applications of WSN.

Get a gentle introduction to the Cocos2d-JS framework to begin working with sprite manipulations, animations, and other 2d game development topics. This book covers environment setup and getting started with a framework that works seamlessly across all browsers. Rapid Game Development Using Cocos2d-JS teaches you the overall architecture of Cocos2d-JS and explains the internal working of the framework. You will dive deep into sprites, the most important entity in Cocos2d-JS, animation APIs, and primitive shapes. You'll also learn about the Cocos2d-JS UI system to get a head start in 2d game development. Finally, you'll discover the features of Chipmunk (the built-in physics engine) with full examples.
