Interesting discussion in the IETF on geonetworking. This geonetworking
is at a very course level. They are thinking using civic level (country,
city, etc) as the geocode. Currently, no discussion of using an actual
coordinate which is interesting as the DHCP extension for encoding
location supports a geodetic (lat/long) coordinate.
Cheers

*Subject:* [geonet/its] Internet-wide Geonetworking problem statement
and challenges/open issues
Hi all,
Below I am giving a brief problem statement description associated with
Internet-wide geonetworking. This description includes the
challenges/open issues that could be worked out by the IETF in a new WG.
In addition to that I am aslo listing requirements that need to be
addressed in order to solve these challenges/open issues.
The goal of this email is to (1) stimulate discussion, (2) modify the
description of the listed challenges/open issues, (3) add new challenges
and (4) modify/add requirements.
Problem:
-------------
Standardized protocol(s) is/are needed to allow source nodes anywhere in
the Internet to disseminate packets to all/any node(s) with geographic
location awareness within a specified destination area.
Challenges/Open issues:
------------------------
o) Mechanisms and/or protocol solutions are needed to ensure that
geographical information is available in the addressing mechanism, such
that packets can be forwarded to a target geographical area.
o) Mechanisms and protocol solutions are needed to ensure that data
packets generated by source nodes placed anywhere in the Internet are
forwarded over multiple hops by using, where possible, the position of
the destination node(s) and the positions of intermediate nodes for the
routing decisions, instead of using their IP addresses.
(Note that in order to solve the above challenge it is NOT mandated that
all nodes located on the path from source to destination nodes are able
to forward packets using the position of the destination node(s) and the
positions of intermediate nodes for the routing decisions. This is
emphasized by using the words ?where possible?.)
Main requirements:
---------------------
The main requirements to be satisfied on solving the above challenges,
(see also:
http://www.ietf.org/id/draft-karagiannis-problem-statement-geonetworking-01.txt):
o) Communication mode: The geoanycast, geounicast and geobroadcast
communication modes MUST be supported by the Internet-wide
geo-networking solution.
o) Security and privacy: The Internet-wide geo-networking solution MUST
support security objectives for all supported communication modes.
Security objectives particularly include integrity, privacy and
non-repudiation and SHOULD protect the network and transport layer
protocol headers.In addition the Internet-wide geo-networking solution
MUST also protect privacy, i.e. provide confidentiality to personal data
such as relation between node identifier and location.
o) Reliable communications: The Internet geo-networking solution SHOULD
support reliable communications with the highest reliability for
messages used for e.g., ITS traffic safety use cases.
Note that more requirements are listed in:
http://www.ietf.org/id/draft-karagiannis-problem-statement-geonetworking-01.txt
Best regards,
Georgios
