Influence of Retransmissions on the Estimating Number of Users Associate in a WLAN Using Error- Prone Channel

Recently, the IEEE 802.11 WLANs are experiencing a vast popularity and widespread deployment particularly with the rapid development in wireless communication technologies. Designing WLANs with traditional steps may allow a specific number of users to utilize from facilities of the networks. The transmission channel condition and number of sharing users are crucial information to be known for the adaptive networks towards achieving better performance. Although numerous of considerable studies investigated estimating number of sharing users in a WLAN utilizes an error-prone channel, influence limited number of retransmissions and type of the accessing transmission channel mechanism on the number of sharing stations are still required more investigation. Therefore, this paper is conducted to analyze these effects. Analytical expressions are presented for studying these effects. The achieved results show that the limited number of retransmissions has a substantial impact on the estimation number of sharing stations using an error-prone channel while type of the access mechanism has ignorable influence on the estimation process.
