A robust and flexible solution for Movement Detection in Wireless IP Networks: Enhanced Lazy Cell Switching

This work has been carried out in the framework of the Whyless.com project, which aims at providing wireless communications, by exploiting the Ultra Wide Band (UWB) technology, and relying on IP as network layer protocol. Our aim is to analyze the behavior of the Mobile IP protocol in micro-pico cellular wireless networks, where handover events are frequent. We decompose the delay introduced by handover procedures into Movement Detection Delay and Handover Completion Delay. While the latter can be effectively reduced by adopting Micro-mobility frameworks and Smooth Handover strategies, the former is still a challenging issue for developers. We primarily focus on Movement Detection (MD) methods and propose a new effective and flexible algorithms that we call Enhanced Lazy Cell Switching (ELCS). We deeply analyze their performance, putting in evidence that our solution exhibits a better behavior.
