ZigBee offers a promising platform for wireless sensor networks. In ZigBee, a node joins a network if it can obtain a free network address from a parent device. ZigBee defines a distributed address assignment scheme with three parameters to facilitate the assignment of addresses. This scheme restricts the device number and the network depth such that the orphan problem might occur. In this thesis, we propose a NAT-based solution to the orphan problem. Also, the private address assignment problem inside the NAT is discussed. This problem is proven NP-Complete and a distributed heuristic is proposed. Finally, the capability of the proposed solutions is shown by the simulation results. Ai-Chun Pang 逄愛君 2008 學位論文 ; thesis 26 en_US
