Abstract

The paper presents a case study where a building automation system is investigated using two wireless standards, ZigBee and Wi-Fi 802.11b. Since each standard has specific features and advantages, a network incorporating both manifests itself as an optimal solution. Previous attempts have been made with successful realisation of systems including both standards. The issue is re-visited in the context of a large warehouse/retailer building and an improved, more flexible solution is proposed. OPNET network modeller is used to study the performance and limitations of the network. Finally, fault-tolerance at the server level is implemented.
