In dense wireless sensor networks (WSNs), packet collisions between sensor nodes degrade the efficiency on power consumption and gathering measured data. In this paper, we focus on IEEE802.15.4/ZigBee, the standardized technologies suitable for WSNs, and form a dense sensor network with cluster-tree topology. We propose a construction method of cluster-tree with multiple channels. The performance of the method is evaluated using computer simulation.
