A QOS Based Prioritized Routing Protocol for Wireless Sensor Network?

Due to vast researches in the field of wireless sensor network (WSN) many routing protocols and scheduling mechanisms have been developed. But the protocols that have a strict constraint on quality of service (QOS) metric are very rare. Scheduling mechanisms must be such that they must cope with the QOS metrics. In many applications of WSNs, different sensor types require different QOSs. This paper proposes a QOS based prioritized forwarding routing mechanism where the sensed data is prioritized based on the requirements, scheduled according to the priority and performance evaluation of the scheme using QOS metrics.
