Today a wired LAN can offer users high bit rates to meet the requirements of band width consuming services like video conferences, streaming video etc. With this in mind a user of a WLAN will have high demands on the system and will not accept too much degradation in performance to achieve mobility and flexibility. The increased demands for mobility and flexibility in our daily life are demands that lead the development from wired LANs to wireless LANs (WLANs). Application requires a quality of service (QoS) and good quality transmission of data packet. So we are using a IEEE 802.11e access method called Enhanced Distributed Channel access method (EDCA),But EDCA not suitable for multi-hop network due to hidden station problem which arise collision in a network.. To solve the problem of and collision carrier sense multiple access with collision avoidance (CSMA/CA) technique are used with jamming signal.
recently lots of companies in the world today make use of the Balanced Scorecard as their tool for managing the organization performance. The main challenge is to have an integrated measurement framework that effectively defines the performance measures and link them to the organizations strategies, then to analyze the represent and report the measured data and analyzing them; here comes the role of the BI as an essential key factor that contributes in presenting and translating the measurement results.
This paper is focusing on adopting the Balanced Scorecard (BSC) as a key framework for managing and measuringthe companiesâ€™ businesses. In addition to being a strong tool for communication of key strategies, the BSC provides clear linkages between strategies, the business processes by which the strategies are executed, and the Key Performance Indicators (KPIs) that measure business performance, moreover,a quick look is provided for how the BSC results can be presented using the business intelligence techniques.
