             draft-baccelli-manet-multihop-communication-04

Abstract

   This document describes characteristics of communication between
   interfaces 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., 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
