Internet-Draft DSR Extensions for Network Coding CapabilityDecember 2015
Abstract
This document describes how DSR [1] can be extended for the support
of network coding capability in the MANET. Because the network coding
capability increases the wireless network capacity, in this draft,
we describe how we can extend DSR for the support of the network
coding capability.

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 this draft, we describe
how the DSR Options header has to be extended to support
the network coding capability.
3. Extensions on DSR Options Header
3.1 Extensions on DSR Route Request Option
The Route Request option in the DSR Options header is extended as
follows:
0 1 2 3
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

IP fields: the same as described in [2]
Route Request fields: the same as described in [3] except for the
N bit
N
The Network Coding bit to indicate whether a MANET node can be
involved in the network coding activities or not. If N bit is 1,
the nodes belonging to the source-to-destination route have to
turn on the network coding capability. The default value of
the N bit is 0.
4. Other Considerations
TBD.
