....since packets can be small and data rates low, low duty cycle radio electronics will be used in the system. However, designing such circuits to be energy efficient is technically challenging. As we will show, current commercial radio transceivers, such as those proposed for the Bluetooth standard [6], are not ideal for microsensor applications since the energy overhead of turning them on and off is high. Thus, innovative solutions in transceiver and protocol design are required to achieve efficient transmission of short packets over short distances. Another challenge arises due to the remote ....

....correlated data, sensor collaboration allows for signal processing of the sensor data (e.g. beamforming) to reduce redundant information. Also it is important to compare communication and computation energy dissipated for a given application. Commercial radios typically dissipate 150 nJ bit [22] [24] versus the StrongARM, which dissipates 1 nJ bit [25] Therefore communication is typically more expensive than computation done on a general purpose processor, allowing one to perform 150 instructions per bit communicated. In comparison, application specific hardware can achieve up to three ....
