In this paper we propose a QoS based routing protocol for wireless sensor network applications that support both periodic and event-based data reporting. A geographic routing mechanism combined with QoS support is used to forward packets in the network. Data is routed based on the packet type. To route packets with different priorities, multiple transmission queues are used. In choosing the next hop, the node that is closer to the sink, has high residual energy, high link quality, and low load is selected. Congestion control is achieved by using a ring or barrier mechanism that captures and aggregates messages that report the same event to the same sink. We present the main operations of the barrier mechanism, including barrier formation, repair, enlarge, shrink, and termination. Simulation results using JIST/SWANS simulator show the performance of our routing protocol compared with other related works.
