| Abstract | ||
| The advent of portable computers and wireless networking has lead to large growth in the data analytic due to the inherent flexibility offered. Most wireless networks are built around an infrastructure, where all communications is routed through base stations that act as gateways between the wireless and wired network. However, there may be situations in which it is impossible or not desirable to construct such an infrastructure. In this research roaming technique in the wireless local area network were investigated, however an scenario of two sub network including two access points and the distance between them ( 2000m ), where the first sub network contained one access point and eight work station mobile while the second sub network contains one access point and four work station mobile. To record computers roaming from one sub network to other and vice versa two work stations would be operates as traffic destined. The proposed scenario analysed (using opnet modeler 14 software ) by transferring first sub netwok computers group to the second one, the data traffic reduced till zero at the first access point after 25 second, which represent the time required to leave the last computers and rested at second sub network location, further more data traffic will be increased and doubled at second access point after roaming operation accomplished. In the second period of the scenario, all computers of second sub network will be roamed to the first one location to study roaming operation effects to all individual components network. | ||
