QoS integrated energy aware routing for wireless sensor networks

Abstract

Quality of service (QoS) in wireless sensor networks (WSNs) has got limited attention due to multiple bottlenecks such as limited bandwidth and energy storage. Until now, most of the focus has been to develop energy efficient routing schemes for WSN. It is important to provide effective QoS mechanism along with energy efficient data transmission. In this work, QoS mechanism is incorporated inside energy aware routing protocol proposed in Shah and Rabaey (2002). This new integrated protocol achieves dual goal of energy efficient data transmission and effective QoS functionalities. Empirical results are demonstrated on NS3 simulator. The proposed approach is compared against existing state of the art technique. The proposed approach outperforms the existing state of the art technique in prolonging the network lifetime.
