Improve QoS performance with Energy Efficiency for IEEE 802.11 WLAN by the Algorithm named Contention Window Adaptation

摘要

In the research of distributed contention based MAC protocol, designing or creating such used protocols for the data transfer and handling functionality to transfer the data packets in system like MAC (medium access control) protocols. In this research main aim is to improve the QoP and energy efficiency in case of transferring the data packets from source location to destination location. The logic behind that algorithm is to minimize the delay to transfer successive packets from source to destination for improving the QoP. And also to increase energy efficiency main logic is to decrease the packet collisions is while transferring, ultimately it save some energy. Some new devices such as laptops, smart phones, tabs etc. which used the wi-fi and WLAN functionality for their use which increases use and deployment of WLANs, with the growth of internet application deployment. There is always some drawback of increased consumption of energy. For that purpose the system uses such network like wi-fi WLAN involves devices which worked with the use of battery. By all above introduction the main aim is to transfer the data packets with the use of such devices by QoS and with minimizing the energy required for such operation in case of IEEE 802.11 n e t w o r k.
