IEEE 802.11b Ad Hoc Network: Performance Analysis is a Primary Issue

The modern dimension of wireless communication technology has created new horizons for communication. Among them, the field of ad hoc networking is experiencing unprecedented growth in its scale and application diversity since it requires no preexistence of communication infrastructures, a temporary network can be established on demand and disappears when there is no need. Due to the proliferation of ad hoc network, the performance measurement of the network is now a primary issue. For this reason, the performance measurements of IEEE 802.11b wireless network operating in ad-hoc mode are investigated. Here the medium is sharing through CSMA/CA mechanism and its effects on the throughput of the network are analyzed by varying the number of clients connected to a single server. In addition, the research works suggest a fair sharing of the channel for clients using the NIC (Network Interface Cards) from the same vendor where there is a tendency to monopolize the channel by different NIC vendor.
