Wireless internetworking protocol (WIP)

In this paper, a novel IP layer protocol is introduced under the name of wireless internetworking protocol (WIP). WIP is designed to provide reliable and continuous data transfer flow in the Internet protocol (IP) layer over wireless communications systems. WIP technology enables the wireless hosts to be mobile while establishing soft handoffs in support of high quality of service (QoS) for real-time data traffic over mobile wireless environments. WIP technology solves some of the fundamental problems of mobile IP (MIP), such as the triangle routing problem and the requirement of redundant buffering, comparing and transferring of stacks of data between the foreign agents and the mobile host (MH) during handoff. Unlike in MIP and ROMIP, where only smooth handoff procedures are possible, WIP enables make-before-brake soft handoff procedures, which enables end-to-end reliability through maintaining transport control protocol (TCP) connections to provide full connectivity during handoff procedures thereby reducing the number of undetectable lost packets during the handoff instants.
