Multi Agent System based Tcp using Seamless Internet Access for Vanet

In this project implement seamless and efficient WIFI-based Internet access from moving vehicles. In our 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. The cellular networks have been proven to be insufficient for the surging amount of data from Internet-enabled 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. 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. seamless in the sense that any user can use it and maintain his workspace, including all existing network connections without manual configuration and with minimal network overhead. In downlink, a packet destined for a client is first pushed to a group of APs through multicast. This AP group is maintained dynamically to follow the moving client.
