Thus, providing ubiquitous connections to/from a mobile device is crucial for various future ZigBee applications. Knowledge of how nodal mobility affects the ZigBee routing protocol is import

Thus far, researchers have been unable to analyze and evaluate the impact of mobile applications via extensive simulations. In this paper, our contribution is threefold. First,
6、 we present an initial implementation of the ZigBee network layer in NS-2, which will allow further research and development to be conducted in this area. Second, we analyze the adequacy of current provisions for dealing with different mobility cases. Third, we provide a comprehensive set of simulat

Introduction With wireless networking technologies permeating nearly every aspect of our working and living environments, simple appliances and numerous traditional wired services can now be efficiently conne
11、cted wirelessly. This provides simple yet effective control/ monitoring convenience, while allowing very interesting applications to be developed on top of these wireless network-enabled gadgets. The ZigBee standard3, which is designed to interconnect simple devices, represents the latest attempt to
12、 realize this wireless network vision. In the business environment, ZigBee wireless technology can facilitate better automated control/management of facilities and assets. Additionally, there are many ZigBee applications for home-appliance networks, as well as in the areas of home healthcare, medica
13、l monitoring, consumer electronics,and environmental sensors. ZigBee is a network and application layer specification developed by a multi-vendor consortium called the ZigBee Alliance. Backed by more than 150 member companies, the ZigBee standard was ratified in late 2004, and released for public non-commercial use in June 2005. Although various ZigBee compliant product prototypes and application scenarios have been developed or defined by the industry, the performance and support facilities of ZigBee networks have not been thoroughly evaluated.
