1. Introduction
Experience gathered with ad hoc routing protocol development,
deployment and operation, shows that wireless communication presents
specific challenges [RFC2501] [DoD01], which Internet protocol
designers should be aware of, when designing solutions for ad hoc
networks at the IP layer. This document briefly describes these
challenges.
2. Multi-hop Ad Hoc Wireless Networks
For the purposes of this document, a multi-hop ad hoc wireless
network will be considered to be a collection of devices that each
have a radio transceiver (i.e., wireless network interface), and that
are moreover configured to self-organize and provide store-and-
forward functionality as needed to enable communications. This
document focuses on the characteristics of communications through
such a network interface.
Although the characteristics of packet transmission over multi-hop ad
hoc wireless networks, described below, are not the typical
characteristics expected by IP [RFC6250], it is desirable and
possible to run IP over such networks, as demonstrated in certain
deployments currently in operation, such as Freifunk [FREIFUNK], and
Funkfeuer [FUNKFEUER]. These deployments use routers running IP
protocols e.g., OLSR (Optimized Link State Routing [RFC3626]) on top
of IEEE 802.11 in ad hoc mode with the same ESSID (Extended Service
Set Identification) at the link layer. Multi-hop ad hoc wireless
networks may also run on link layers other than IEEE 802.11, and may
use routing protocols other than OLSR (for instance, AODV [RFC3561],
TBRPF [RFC3684], DSR [RFC4728], or OSPF-MPR [RFC5449]).
Note that in contrast, devices communicating via an IEEE 802.11
access point in infrastructure mode do not form a multi-hop ad hoc
