At present, cellular networks provide ubiquitous Internet connection, but with relatively expensive cost. Furthermore, the cellular networks have been proven to be insufficient for the surging amount of data from Internetenabled mobile devices. Due to the explosive growth of the subscriber number and the mobile data, cellular networks are suffering overload, and the users are experiencing service quality degradation. In this project implement seamless and efficient Wi-Fi based Internet access from moving vehicles. In our proposed implementation, a group of APs are employed to communicate with a client (called AP diversity), and the transmission succeeds if any AP in the group accomplishes the delivery with the client (called opportunistic transmission). Such AP diversity and opportunistic transmission are exploited to overcome the high packet loss rate, which is achieved by configuring all the APs with the same MAC and IP addresses. With such a configuration, a client gets a graceful illusion that only one (virtual) AP exists, and will always be associated with this virtual AP. Uplink communications, when the client transmits a packet to the virtual AP, actually multiple APs within its transmission range are able to receive it. The transmission is successful as long as at least one AP receives the packet correctly. Proposed implementation will show that outperforms existing schemes remarkably.
