Wireless sensor networks have been extensively adopted in numerous application scenarios. However, increasing environmental constraints and performance requirements has spurred the development of tools to expedite deployment and minimize human intervention. This study extends previous work by the authors in network development and aims at the performance evaluation of applications operating in to-be-deployed networks. We prove that the determination of a ZigBee cluster tree over an underlying network is NP - hard and propose an algorithm for generating tree topology. Based on the proposed algorithm/technologies, an integrated development tool is developed. The capability of the tool is demonstrated by a case study of the system deployed in an office building.
