In this paper, the authors study passive discovery of IEEE 802.15.4 networks operating in the beacon-enabled mode. The task of discovery occurs in different scenarios. One example is a simple device that wishes to associate with a specific, pre-specified PAN coordinator (targeted discovery). Another example is opportunistic relaying applications, where arbitrary foreign coordinators should be discovered (untargeted discovery). They consider a simple class of listening strategies and provide different analytical models which allow to find optimal strategies for different listening scenarios. For the case of targeted discovery without constraints on the listening costs they give a dynamic programming formulation, for targeted discovery with bounded costs they present and validate a simple model and derive the desired performance measures.
