Abstract
In a network which is IEEE 802.11 based, handoff is a challenging issue. When mobility rate of the mobile station is very high, it becomes more challenging. If it takes too much time, Quality of Service (QoS) provided to the users will decrease. Handoff consists of three parts, namely scanning, authentication and association. Out of these, the scanning process consumes maximum time. It is very necessary to reduce the time required for scanning. In this paper, a selective scanning-based technique has been proposed to increase the efficiency of the network. The host Access Point (AP) assists the mobile station to select the channel which is to be scanned. The proposed scheme has been simulated in NS-3. From the performance comparison, it has been observed that the proposed scheme performs better than that of IEEE 802.11g with respect to mean delay, packet loss ratio, jitter and throughput.
