Internet-Draft Requirements on Network Coding Support December 2015
Abstract
This document describes the requirements on providing the network
coding capability in the mobile ad hoc network (MANET). For this,
the conditions to be considered in providing the network coding
capability in the MANET are listed.

Internet-Draft Requirements on Network Coding Support December 2015
1. Requirements notation
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].
2. Introduction
The mobile ad hoc network (MANET) is composed of a number of mobile
nodes which can communicate with each other through multiple
wireless links without the help of a wired infrastructure.
Because a wireless link is more restricted in its capacity than a
wired link, the efficient utilization of wireless links is one of
the important issues in wireless networs, especially in the MANET.
The network coding is one of the mechanisms that can increase
wireless network capacity [1]. In order to provide the network
coding capability in the MANET, there are many things to be
considered.
In this draft, we define the requirements on supporting the network
coding in the MANET.
3. Requirements on the Provision of Network Coding
In applying the network coding capability to the MANET, the
following considerations have to be accomponied with:
- the delay incurred by waiting at nodes to increase the possibility
of encodings in a source-to-destination route
- the number of encodings and decodings experienced by a packet
in a source-to-destination route
- the throughput perceived at destinations
- the base MANET unicast routing protocol, such as AODV [2] or DSR
[3], on which the network coding capability is applied
- the degree of changes on the base MANET unicast routing protocol
With considering the above-mentioned conditions, the provision of
the network coding capability in the MANET SHOULD satisfy the
following requirements:
- The delay incurred by the network coding capability SHOULD be
controlled such that it does not exceed a certain amount
- The number of encodings and decodings SHOULD NOT exceed a given
threshold

- The modifications and/or extensions on the base MANET unicast
routing protocol SHOULD NOT hinder the operation of the base MANET
unicast routing protocol.
4. Other Considerations
TBD
