This paper describes a Directed Query Dissemination Scheme, DirQ that routes queries to the appropriate source nodes based on both constant and dynamic-valued attributes such as sensor types and sensor values. Location information is not essential for the operation of DirQ. DirQ only uses locally available information to route queries accurately and to allow nodes to adapt autonomously to changes in network topology. This is due to certain cross-layer features that allow it to exchange information with the underlying MAC protocol. Our simulations illustrate how both the accuracy and efficiency of the routing of queries are affected by the chosen level of threshold.
