Wireless Sensor Network (WSN) is based on distributed event-based system that is different from the traditional communication network. The main goal of the network is to deliver a data packet with the highest efficiency and quality of service. In WSN, Quality-of-Service (QoS) is an important performance indicator, therefore the QoS routing protocols are designed to provide more efficiency and quality of service. Here they concentrate on SPEED (Stateless Protocol for End-to-End Delay) protocol is a QoS based protocol and which provides efficiency, softness-real time communication, desired delivery speed and a low overhead over the network.
