DESCRIPTION:
A group of mobile wireless nodes capable of spontaneously forming
network and support multi-hop communications constitutes a mobile ad hoc
network (MANET). One of the main reason for popularity of manet is that
it does not rely on any existing infrastructure. Several manet routing
protocol specifications have been developed by IETF's MANET WG. However,
currently there is no standard specification that can be used by manet
nodes to auto-configuring its IP address and other network parameters.
For IP-based infrastructure network there are several specifications for
this purpose such as RFCs 2461, 2462,3315 etc. However, considering the
unique properties of ad hoc networks such as multi-hop packet
forwarding, absence of infrastrastructure e.g. DHCP server, these
specifications cannot be directly used by nodes constituting ad hoc
network.
The main goal of the MANET AUTOCONF is to develop solutions for IPv4 and
IPv6 address auto-configure that are either manet-local scope i.e. valid
only within a particular ad hoc network or global scope i.e. addresses
that
are routable on the global Internet.
Stand-alone ad hoc network:
Such ad hoc networks are not connected to any external network e.g.
Conference network, battlefield network, surveillance network, etc. For
such manet, solutions for IPv4 and IPv6 address auto-configuration,
duplicate address detection and resolution will be developed
considering situation where nodes may be added or removed randomly. Any
address autoconfiguration mechanism for such networks should take care
of the lack
of any pre-established and reliable address or prefix allocation agency.
Ad hoc network at the edge of infra-structure network:
Stand-alone network connected to the Internet via one or more Internet
gateways i.e nodes sitting in between the two networks comes under this
scenario. Internet gateway may be either fixed or mobile, single or
multiple, equipped with wired and/or wireless interfaces and should be
able to provide global addressing as well as bidirectional connectivity
to those manet nodes connected to it either directly (1-hop) or through
one or more intermediate nodes. Manet nodes may use Internet gateway for
prefix allocation. Presence of Internet gateway may make address
configuration mechanism comparatively simple but introduces other issues
such as how manet nodes receive or Internet gateway provides
topologically correct routing prefix to the manet nodes, how to select
gateway, etc.
Hence, for such network sufficient detail about Internet gateway will be
provided, along with address autoconfiguration solution.
The third scenario where ad hoc network may be stand-alone for most of
the time but temporarily connected to the infrastructured network e.g.
car network connected while parked and disconnected otherwise, will also
be
considered.
Two or more ad hoc network may join together or single ad hoc network
may get partitioned into two or more separate networks, at any moment of
time.
While network partitioning may not cause any severe problem to the node
functioning, network merging may create problem by introducing more than
one node in a MANET with the same address. Hence, appropriate mechanism
should be provided in order to ensure uniqueness of the configured
interface addresses after network merger. Any other problem arising due
to network
merger and partitioning should also be taken appropriate care.
