  • Wireless communication slowly is becoming reality. In a wireless world, a printer is installed automatically after it is turned on; keyboard and mouse cables no longer become hopelessly tangled; Palm Pilots and mobile telephones automatically synchronize and communicate. Providing this sort of seamless, wireless communication--at a low cost--is the goal of Bluetooth technology. Devices that support Bluetooth automatically communicate with one another when they come within a 30-foot range of each other.

  • Bluetooth is an open standard for short-range radio frequency (RF) communication. Bluetooth technology is used primarily to establish wireless personal area networks (WPAN), commonly referred to as ad hoc or peer-to-peer (P2P) networks. Bluetooth technology has been integrated into many types of business and consumer devices, including cellular phones, personal digital assistants (PDA), laptops, automobiles, printers, and headsets. This allows users to form ad hoc networks between a wide variety of devices to transfer voice and data.

  • Introducing Bluetooth Applications notwithstanding, the added value from simply being wireless convinced consumers to try it and use it! However, for products that are inherently static, the added value may just be initial “desire” and not really a viable investment in both resources and dollars. Consider the static devices in our wired PAN (Figure 1.1)—for example, the ubiquitous mouse and keyboard. Both are dependant for their power supply requirements upon their host PC, so if made wireless, the subject of batteries becomes crucial....

  • Over the past decade, there has been a prolific increase in the research, development and commercialisation of Wireless Sensor Networks (WSNs) and their associated technologies (see Figure 1). This rise has been a result of a number of contributing factors, including continued miniaturisation (leading towards an era of truly ‘pervasive’ and ‘invisible’ computing); low-power circuits, devices and computation (for example, the ultra-low-power sleep states now found in microcontrollers); and efficient short-range communication (such as ZigBee and Bluetooth).
