Such microsensors are required to operate for years from a small energy source. To minimize the energy dissipation of the sensor node, RF front-end circuitry must be designed based on system level optimization of the entire network. This paper presents several energy minimization techniques derived from the unique properties of a practical short range asymmetric microsensor system. These include energy e cient modulation schemes, appropriate multiple access protocols, and a fast turn-on transmitter architecture.

متن کاملTR-MAC: An Energy-E cient MAC Protocol for Wireless Sensor Networks exploiting Noise-based Transmitted Reference Modulation
Energy-constrained behavior of sensor nodes is one of the most important criteria for successful deployment of wireless sensor networks. The medium access control (MAC) protocol determines the time a sensor node transceiver spends listening or transmitting, and hence the energy consumption of the overall node. Transmitted reference (TR) modulation as the underlying physical layer provides new o...
