centralized access network for 18 people that is easy to manage and back up. They need server-based network because peer-to-peer network model has no centralized authority or control over resources. On the other hand‚ server-based network provides centralized control over network resources and will have secure access to project files and will fulfill company’s need for centralized management and back up requirement. So‚ all of these factors are the key reasons for using server-based network. Case Project

Abstract - ZigBee Technology is a progression in wireless technology. Wireless is not a new technology as wireless internet are already in use; yet Zigbee technology set a new aspect in wireless technology. ZigBee is a low-cost‚ low power‚ wireless mesh network standard. The low cost allows the technology to be widely deployed in wireless control and monitoring applications. Low power-usage allows longer life with smaller batteries. This paper gives an overview of the ZigBee Technology and covers an application
