According to multiconstrained characteristics of Wireless sensor networks (WSNs), we need to forward collected data in quality of service (QoS) based. Many applications of WSN, such as target tracking, forest fire detection and biomedical, have diverse data traffic such as normal, reliability-sensitive, delay-sensitive and critical packets with different QoS requirements. A typical example of such a scenario is patient monitoring in a hospital room, where different health parameters are to be captured and forwarded to health care servers accessible by the medical staff. This survey investigates Qos-based routing protocols for wireless sensor networks. The main objectives of QoS-based routing protocols are to provide reliable and real-time communication and to ensure prolonging network lifetime. The goals are to improve delay, provide reliability, reduce overhead and maximize network lifetime. Issues, objectives, performances, advantages and disadvantages of these protocols are investigated and summarized, of service, routing protocol, Energy efficiency, Critical mission. © IDOSI Publications, 2011.
