Reliable and real-time data dissemination in wireless sensor networks

In wireless sensor networks, both real time and reliable transmission are the big research challenge. But current approaches in these research fields have not been well explored because there are so many restrictions on respective sensor node. In this paper, we propose a new reliable real time routing protocol in sensor networks. For real time delivery, we introduce a time-based forwarding scheme in wireless sensor networks. In addition, reliable transmission is accomplished by multiple transmissions based on link quality in such a distributed way. Finally, simulation results are presented to demonstrate the proposed scheme meets real time and reliable transmission in wireless sensor networks.
