A real-time energy-aware routing strategy for Wireless Sensor Networks

Recent advances in wireless technology have enabled the rapid development of Wireless Sensor Networks (WSN). It consists of ten to thousands of randomly deployed nodes collaborating to achieve a goal. WSN are used in a variety of applications [9]. In this paper, we are developing a real-time routing protocol for wireless sensor networks. Our goal is to provide "reliable" and "real-time" packet delivery services differentiating packets depending on their urgency and importance. The protocol can achieve the goal in a localized way based on geographic routing. Since it relies on only local decisions of individual nodes without global network information, it preserves nice properties such as scalability, self-healing, and adaptability while continuously guaranteeing real-time and reliability requirements of packets.
