One of the main challenges of wireless communications is interference. Transmitters around a receiving sensor node cause interference for that node as long simultaneous transmissions occur in wireless sensor networks. Reducing interference results in less collision of communicative signals as well as less retransmission of information packets. Hence, appropriate scheduling is required to avoid interference. Suppressing interference reduces indirectly power consumption and delay; meanwhile increases the network lifetime. In this paper, an energyaware routing algorithm is proposed to reduce both interference and delay simultaneously. The proposed routing algorithm creates a tradeoff between interference, delay and energy consumption in the sensor network. This routing method is based on the network geography; while energy, interference and delay criterions are utilized to select relay nodes transmitting data from the source node to the destination node or the cluster head. Stimulations results show the tradeoff between interference and delay in the proposed routing algorithm, which not only increases the network lifetime but also enhances network performance.
