Use case: Dissemination of IP packets to
geographical areas
draft-karagiannis-geonet-dissemination-geo-areas-00
Abstract
This document describes the use case where IP packets are
disseminated to geographical areas, based on geographical location
information. A source node, which may be located anywhere, sends
packets to an access router through the Internet.
Those access routers are selected based on geographical location
information, and traffic is routed to them using the IP address of
the router and conventional IP routing. Each of the destination
access routers then copies and broadcasts the received packets to
listeners within its (1) radio coverage for wireless access routers
or (2) IP subnet for wired access routers.

1. Introduction
Internet-based applications are currently using IP addresses to
address interfaces of a node that can be for example a host, a
server or a router. IP routing and addressing are completely unaware
of geographic parameters such as coordinates or postal addresses.
Future applications and use cases have been identified that need to
support among others the dissemination IP packets to geographical
areas. This document describes the use case where IP packets are
disseminated to geographical areas, based on geographical location
information.
This document is organized as follows. Section 2 presents the
terminology. Section 3 provides the brief description of this use
case. Section 4 provides the security considerations. The IANA
considerations are given in Section 5. Section 6 gives the
acknowledgements and Section 7 lists the used references.
2. Terminology
Internet-wide Geo Networking
the solution space that includes mechanisms and protocols used to
disseminate packets sent by authorized source nodes located
anywhere in the Internet to other nodes in areas described by
geographical parameters.
Geographic coordinate system:
a coordinate system that enables every location on the Earth to be
specified by a set of numbers or letters.

3. Dissemination of IP packets to geographical areas
This use case applies to any source node that is located anywhere in
the Internet and based on geographical location information, needs to
send packets to destination nodes located in a geographical area.
Such source and destination nodes can be used in many types of
applications, such as: environmental monitoring, consumer electronic
devices (e.g. cameras) and scientific instruments.
Such a source node, needs to send IPv4 or IPv6 packets to any
destination node that is located in a certain geographical area.
Therefore, the only addressing information that the source nodes can
use is the geographical coordinates of the given area.
In this use case it is assumed that within the given geographic
area a communication infrastructure exists, where wireless access
routers, see Figure 1 and wired access routers, see Figure 2 are
supported.
A solution is needed, where the access routers are selected based on
the available geographical location information, and where the
traffic is routed to them using the IP address of the router and
conventional IP routing. Each of the destination access routers then
copies and broadcasts the received packets to listeners within its
(1) radio coverage for wireless access routers, see Figure 1, or (2)
IP subnet for wired access routers, see Figure 2, where either IPv4
subnet broadcast or IPv6 multicast addressing to the all-hosts
multicast group techniques can be used.
Internet-wide Geo Networking (GeoNet) can be used to provide the
above described solution.

4. Security Considerations
Due to the sensitivity of location data and the possibility of the
technology being used in emergency and/or road traffic management
scenarios a particular attention must be paid to security and
privacy. Security objectives particularly include integrity, privacy
and non-repudiation and SHOULD protect the network and transport
layer protocol headers. In addition any potential Internet-wide Geo-
networking solution MUST also protect privacy, i.e. provide
confidentiality to personal data and protect leaking
information through protocol behavior, such as the relation between
identifier and location.
5. IANA Considerations
No IANA considerations are considered in this document.
