Reduce 802.11 Connection Time Using Offloading and Merging of DHCP Layer to MAC Layer

With the growth of Wi-Fi by the time, performance and quality are facing quite a lot of challenges. Wi-Fi works on the principle of the IEEE 802.11 based carrier sense multiple access – collision avoidance (CSMA/CA) to transmit packets and distributed coordination function (DCF) protocol based on Inter-frame spacing used to make the gap between two frames. In this manner, an 802.11 device gets limited time in the environment to finish its activity, with a rapid increase in the number of devices in the 802.11 environments. The important operation is always a connection of Wi-Fi device with another device, another device can be an Access point or any other Wi-Fi device (ad-hoc or Wi-Fi direct mode). Several researchers work on why connection time is more important and what factors affect its most [1, 2]. In this paper, we describe a way to reduce connection time with the use of cross-layer approach via offloading DHCP work to the MAC layer.
