Security Issues and Energy Consumption in Implementing Wireless Sensor Networks
Sensors have been implemented to read information from physical devices in order to use this information for multiple purposes. Sensors convert analog signals to digital signals for processing and computation purposes. ‘A sensor is a type of transducer that converts energy in the physical world into electrical energy that can be passed to a computing system or controller’. The Internet has become an indispensable means of sourcing and storing information. In the future, the Internet will be used to control objects, not just information. This raises the issue of security. In the case of wireless sensor networks, the main challenge will be to provide secure lines of communication between devices on the same network.
