Cellular data networks have recently seen an explosion in their usage due to the widespread deployment of 3G technologies and the rapid proliferation of smartphones. People are increasingly using their smartphones on the go and expect always-on, high quality connectivity at all times. A key network primitive that enables continuous connectivity in cellular networks is handoff, or the transfer of a device's connection from one cell sector to another. Although handoffs are necessary for mobile devices to maintain connectivity, a recent study showed that handoffs generally cause short-term disruptions in application performance.
