Abstract
This document describes characteristics of communication between
nodes in a multi-hop ad hoc wireless network, that protocol engineers
and system analysts should be aware of when designing solutions for
ad hoc networks at the IP layer.

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., a wireless network interface), that
are using the same physical and medium access protocols on their
respective wireless network interfaces, and that are moreover
configured to self-organize and provide store-and-forward
functionality on top of these protocols as needed to enable
communications. The devices providing network connectivity are
considered to be routers. Other non-routing wireless devices, if
present in the ad hoc network, are considered to be "end-hosts". The
considerations in this document apply equally to routers or end-
hosts; we use the term "node" to refer to any such network device in
the ad hoc network.
Examples of multi-hop ad hoc wireless network deployment and
operation include wireless community networks such as
Funkfeuer[FUNKFEUER] and Freifunk[FREIFUNK]; these use routers
running OLSR (Optimized Link State Routing [RFC3626]) on 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 802.11, and may use
