A P2P approach for automating seamless connectivity given intermittent bandwidth constraints

With the advancement of wireless technologies, seamless connectivity is near to becoming possible. In this paper, we propose a novel idea to attain seamless connectivity in the presence of intermittent bandwidth availability. Critical services/applications are required to deliver without any issues every time and throughout. Intermittent bandwidth availability is one of the many hindrances and a bottleneck for seamless connectivity. In a client-server model when the bandwidth availability is less, the subscribed services may not deliver as desired by the end user. Hence, we propose a P2P based seamless connectivity solution given intermittent bandwidth constraints which automatically switches between client-server to P2P model when there is intermittent bandwidth availability. We assume vertical and horizontal hand-offs in our architecture for switching between client-server to P2P model. We propose an automatic switching of these hand-offs. We approach the problem of seamless connectivity in intermittent bandwidth availability by gathering data in a P2P network which is scattered across different peers by using a set cover heuristic algorithm. The algorithm proposed selects the right set of peers in the P2P network for all the services which was getting serviced by client-server model.
