Although Wireless Sensor Networks (WSNs) have been extensively researched, its deployment is still a main concern. The authors observe that many monitoring applications for WSNs have adopted a Path-Connected-Cluster (PCC) topology, where regions to be monitored are deployed with clusters of sensor nodes. Since these clusters might be physically separated, paths of sensor nodes are used to connect them together. They call such networks PCC-WSNs. PCC-WSNs may be widely applied in real situations, such as bridge-connected islands, street-connected buildings, and pipe-connected ponds. In this paper, they show that the address assignment scheme defined by ZigBee will perform poorly in terms of address utilization.
