A Differentiated Real-Time Routing Protocol Along with Re-Routing Policy in Wireless Sensor Networks

Sayyed Majid Mazinani, Elham Sadr, and Ali Naderi

Abstract— Many wireless sensor network (WSN) applications require real-time communication. One of the most important and challenging issues in real-time applications of resource-constrained WSNs is providing end-to-end delay requirement. To address such an issue a few QoS routing protocols have been proposed. Also, in many applications, the delay level required by the data packets is different. In this paper, we focus on building a real-time routing protocol called DRTR which routes packets towards the destination node by classifying data into differentiated classes. DRTR improves real-time performance by means of reducing the packet dropping in routing decisions. It is a power-aware routing protocol which takes into account both power transmission costs and residual energy of routers to achieve power efficiency. Moreover, DRTR employs a new policy called re-routing policy which allows the packets of a specific class to be routed as the packets of a lower/higher real-time class in particular situations.

Index Terms— Differentiated real-time routing, power-aware routing, re-routing policy, wireless sensor networks.
