In Wireless Sensor Network (WSN), QoS (Quality of Service) in sensor application plays a very important role.QoS based routing is required to ensure the best use of nodes in WSN.In this paper, a comparative study of QoS based routing in Media Access Control (MAC) protocols are presented based on the traits to solve problems like prioritization, timeliness, reliability etc.The study mainly focuses on some priority based QoS protocols used in WSN and a comparison among them.The study reveals that among the five mentioned protocols; QMAC, PRIMA, DB-MAC, RAP, GTS; PRIMA shows the best performance in the category of Packet Prioritization, Scheduling Scheme, Queue Type, Energy Awareness and QoS.
