Transmission Power Control with the Guaranteed Communication Reliability in WSN
International Journal of Distributed Sensor Networks, 2015 In a wireless sensor network, sensor nodes are deployed in an ad hoc fashion and they deliver data packets using multihop transmission. However, transmission failures occur frequently in the multihop transmission over wireless media. Thus, a loss recovery mechanism is required to provide end-to-end reliability. In addition, because the sensor nodes are
