Abstract

Wireless sensor network (WSN) has been used widely in vehicular on-board monitoring area. In the scenario of vehicular monitoring, the wireless sensor nodes share similar electromagnet environment. This phenomenon can be used by the sending node to infer the receiver’s noise level. Moreover, the sender can decide the transmitting power accordingly. In this paper, we proposed a interference-aware approaching to control the transmission power of nodes in a vehicular on-board monitoring WSN. By making use of the relationship of noise level on the sender side and the receiver side, the sender node can decide the necessary transmitting power to send a packet successfully. Because the packets are sent at high enough transmission power, the Packet Reception Rate (PRR) is improved. At the same time, the network latency caused by communication failure is reduced. DOI: http://dx.doi.org/10.11591/telkomnika.v10i5.1351
