Routing Protocols to provide Quality of Service in Wireless Sensor Networks

Abstract: Wireless Sensor Networks consist of small, low-power, low-energy nodes used for monitoring environmental parameters such as temperature, humidity and motion. Routing is a critical issue in WSN and hence the WSNs are required to provide different levels of Quality of Services (QoS) based on the type of applications. Due to resource constraints like processing power, memory, bandwidth and power sources in sensor networks, QoS support in WSNs is a challenging task. In this paper, we discuss the QoS requirements in WSNs and present a review on some of the QoS aware routing protocols in WSNs. In the end, we have done the comparison of QoS aware routing protocols in WSNs. 1, 2 Index Terms:- Wireless Sensor Networks(WSN), Quality-of-Service(QoS), LEACH, Routing Protocols. the surrounding environment and finally forwards the 1
