A Survey on QoS Provision Techniques in Wireless Sensor Network

The latest features developed in Wireless communications have provided maximum opportunities to enable new applications and to develop low-cost wireless sensor network. This low cost sensor networks might be used for several communication networks such as industrial monitoring, military applications, temperature measurement, event detection system and many more like these. And a huge effort of the researchers has resolved different techniques, algorithms, Protocols and models for different applications in different areas. This paper is a review of QoS Provision Techniques, Protocols and Standards in Wireless sensor networks and to discuss the new and different kind of applications in wireless sensor network. The existing protocols, models and techniques are classified and compared. Furthermore, we study trade-off among end-to- end delay, reliability and energy consumption in Wireless Sensor Network as well as open issues and challenges for future research work are also discussed in detail.
