Cell-Search List Indications for Seamless Anticipative, Resource-Mindful Handovers
ICR, NUS
In 802.11 or similar technologies, the network device enters a 'cell-search mode' when the signal level/quality of the serving AP drops below a certain value. In the cell-search mode, the device actively measures the signal level and/or quality of neighbouring APs in addition to that of the serving AP. This document describes how the use of MN originated cell-search list indications, which carry signal level and signal quality measurements of access points in the immediate vicinity of the mobile node, can assist in a handover scheme that factors in seamlessness, target router selection, context transfer and resource usage information.
