Review of Quality Of Service in Routing Protocols for Wireless Sensor Networks

Rapid innovative improvements in wireless communication technology have revolutionized Wireless Sensor Networks (WSNs). A WSN is comprised of self-ruling sensors that are distributed spatially to monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion, or pollutants and to pass this information through the network to a main area. Sensor nodes in wireless sensor networks experience the ill effects of resource constraints, such as energy deficits, buffers, and bandwidth issues. The expanding demand for real-time services in WSN applications means that interest in Quality of Service (QoS)-based routing has risen.
