The Seamoby Candidate Access Router Discovery, or CARD, is an experimental protocol outlined by RFC 4065 and RFC 4066.[1][2]
The protocol is designed to speed up the hand over of IP devices between wireless access routers (AR).[1] The protocol defines a mechanism that can be used by an access router to automatically discover its neighbor with help of mobile devices.[2] Based on some trigger, mobile devices scan for neighbor access points (AP) and report list of newly found access point identifiers to the connected access router.[2] The connected access router performs reverse look up using AP id(s) to identify the candidate access routers that are connected to the newfound access points.[2] The connected access router updates its neighbor list with IP address and capability of newly found access routers. The neighbor list can be used for inter-AR handover decision making.[2]
A similar idea is currently used by 3GPP SON protocol (aka ANR) for discovering candidate access points. However, ANR protocol extends RRC and X2 protocols to support CARD-like functionality for L2 networking.
The SEAMOBY working group was disbanded in fall 2004.[3]
