Spatial Location BOF (spatial)

Thursday, March 30 at 0900-1130

DESCRIPTION:

The purpose of this BOF is to address spatial location discovery, 
information, exchange, and utilization for IP devices. The objective of 
this BOF is to let IP devices and applications be able to represent 
their spatial location information, established through other approaches, 
in an agreeable manner and authenticatedly communicate that information 
with other IP devices and applications.  Security is a fundamental 
requirement for many situations of the data exchanges and applications. 
It is an inseparable part of the objective.

The problem intended to answer is two-fold: (1) How can an IP device, 
even if mobile, represent its physical location information, determined 
by an other approach, in a recognizable format; and (2) How can two IP 
devices, whether end IP devices, network servers or spatial location 
servers themselves exchange location information reliably? The problem 
has many facets or items for the consideration.  Here are some of the 
items that need to be investigated: 

(a) Spatial locality information expressions (including accuracy and 
    associated privacy policy) and the data format for exchange
(b) Authentication needs at different levels such as device level, user 
    level, and server level
(c) Security requirements and approaches for the data exchange
(d) Requirements and approaches (including security) for an IP device to 
    verify the location information received from the exchange when needed 
    and authenticated to do so 
(e) Characteristics of an IP device and its spatial location based services 
    as well as the way for one to identify them
(f) A common language for an IP device to specify the characteristics and 
    services interested to or offered by it
(g) Various scenarios risen from different types and relationships of the 
    IP devices including relative vs. absolute location to another IP device
(h) Usability constraints for solving the problem.


Here, an IP device is a device which is addressable via IP. The device may 
be the host which is addressable by IP or an element within the host. In 
addition, an IP device can be a physically static or moving IP device. The 
spatial location is the physical spatial location of an IP device. The 
issues of virtual location and virtual time should be specified by certain 
service characteristics. The intended work addresses both IPv4 and IPv6.
