In the world of wireless communication, the Medium Access Control (MAC) protocol sports a pivotal task in managing access to the shared communication medium. This project proposes a change to the existing IEEE 802.11 MAC protocol by introducing a modification in the sensing process. The conventional algorithm incorporates Short Inter-Frame Space (SIFS), DIFS (Distributed Inter-Frame Space) and backoff periods to regulate channel access. The proposed modification seeks to experiment the protocol by eliminating SIFS, thereby focusing solely on backoff and DIFS. This will reduce the delay each node waits before transmitting the packet. Eventually the reduction in wait time, reduces the energy consumed thus optimized the energy usage of nodes. To evaluate the efficacy of the modified protocol, a wireless network simulation is conducted in NS2. The simulation provides insights into the behavior of the network under the altered MAC protocol, shedding light on its performance and potential advantages.
