Abstract

   This document describes some characteristics of communication between
   nodes in a multi-hop ad hoc wireless network.  These are not
   requirements in the sense usually understood as applying to
   formulation of a requirements document.  Nevertheless, protocol
   engineers and system analysts involved with designing solutions for
   ad hoc networks must maintain awareness of these characteristics.

1.  Introduction

   The goal of this document is to describe some aspects of multi-hop ad
   hoc wireless communication.  Experience gathered with [RFC3626]
   [RFC3561] [RFC3684] [RFC4728] [RFC5449] [RFC2501] [DoD01] shows that
   this type of communication presents specific challenges.  This
   document briefly describes these challenges, which one should
   maintain awareness of, when designing Internet protocols for ad hoc
   networks.

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, that are using the same physical and medium
   access protocols, 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.

   An example of multi-hop ad hoc wireless network is a wireless
   community network such as Funkfeuer [FUNKFEUER] or Freifunk
   [FREIFUNK], that consists in routers running OLSR [RFC3626] on 802.11
