Mobility for heterogeneous SmallNets

In this paper we consider mobility in a network of converged small-cell gateways, each capable of aggregating cellular and unlicensed bandwidth by combining a WiFi AP and a cellular base station within a single-box. A network of such gateways must provide mobility services in a decentralized fashion and we demonstrate how this may be accomplished by taking advantage of Proxy Mobile IPv6 (PMIP) - the network-based version of the Mobile IP protocol. We also describe how the placement of the single-box allows for an improved user experience, increasing throughput and maintaining IP Flows when either the cellular or WiFi connections degrade.
