Real-time routing in wireless sensor networks

Abstract

In Wireless Sensor Networks (WSNs), sensors gather information about the physical world and base station makes appropriate decision upon the environment. This technology enables users to effectively sense and monitor from a distance. WSN are slated to become very popular in the near future. It allows video/audio streaming to be transferred between sensor nodes in real-time. WSN can use real-time forwarding which means messages in the network are delivered according to their end-to-end deadlines (packet lifetime). This paper proposes a novel real-time routing protocol based on link quality, packet velocity over one-hop and remaining power in the sensor devices. The proposed routing has been successfully studied and verified through simulation and real test bed implementation. The results in this paper show that the proposed routing protocol has efficient power consumption, high packet delivery ratio and minimum control packet overhead in WSNs.
