IP-layer soft handoff implementation in ILNP

Date of Acceptance: 14/07/2014We present the first results of an implementation of IP-layer soft handoff, based on the Identifier Locator Network Protocol (ILNP). In our testbed experiments, we show minimal gratuitous packet loss in vertical handoff scenarios (WiFi-3G). Unlike the IETF Mobile IP proposals, the ILNP uses a purely end-to-end architecture, and does not require proxies, middleboxes or tunnelling to support mobility. Our testbed is based on an in-kernel implementation using a modified Linux IP stack.Postprin
