Abstract: This paper focuses on the enhancement of MAC protocols particularly the Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) for IEEE 802.11g standard. In this paper, the protocol was analysed in term of throughput and transmission delay by using an improved analytical approach using MATLAB. The saturation throughput analysis of CSMA/CA is controlled by using slotted analytical model combined with captured effect probability model. The performances of MAC protocols with propagation loss and shadowing scenarios are analysed. The proposed modification significantly reduced the probability of collision and recorded better performance. The maximum throughput of MAC protocol is dependent on the normalized propagation delay. In other words, smaller normalized propagation delay gives better performance of throughput. On the other hand, shorter distance has higher throughput and lower transmission delay for both path loss and shadowing scenarios, in comparison to the longer distance. With the deployment of MAC protocols with capture effect, the average transmission delay significantly shows better performance.
