Abstract—With the increasing demand for real time applications in the Wireless Senor
Network (WSN), real time critical events anticipate an efficient quality-of-service (QoS)
based routing for data delivery from the network infrastructure. Designing such QoS
based routing protocol to meet the reliability and delay guarantee of critical events while
preserving the energy efficiency is a challenging task. Considerable research has been
focused on developing robust energy efficient QoS based routing protocols. In this paper,
we present the state of the research by summarizing the work on QoS based routing
protocols that has already been published and by highlighting the QoS issues that are
being addressed. The performance comparison of QoS based routing protocols such as
SAR, MMSPEED, MCMP, MCBR, and EQSR has also been analyzed using ns-2 for
various parameters.
