Bandwidth Allocation for Vehicle Based Nodes in Heterogeneous Wireless Networks
The present work proposes a communication system to ensure Internet connectivity and network transparency
to a group of nodes within a vehicle in heterogeneous wireless networks environment. It considers the integration of three
networks. Each vehicle is equipped with multiple cares of addresses corresponding to multiple network interfaces. The
proposed scheme provides uninterrupted Internet connectivity to the nodes inside a vehicle while the vehicle moves. It allows
communication among a correspondent node and a node inside a vehicle using a suitable care of address for balancing
the load among the various wireless access networks. Each network reserves a fraction of the total resource for the
processing of handoff session request and new session request depending upon their arrival probability. It entertains a session
request only if the desired resource is available which helps to maintain the user satisfaction of the already admitted
users in the network to a satisfactory level.
