Robust MANET Routing using Adaptive Path Redundancy and Coding
|
|
| Abstract |
|
|
Providing efficient networking services in MANETs
is very challenging due to mobility and unpredictable radio
channel: a significant number of packets can be corrupted
and/or lost. To increase reliability, various measures have been
proposed. A popular approach is to use multiple paths and
transmit an identical copy of the packet on each path (i.e.,
path redundancy). A more efficient way is to use Network
Coding on top of path redundancy and send different, encoded
packets on each path. Network coding can improve throughput
efficiency. However, it increases delays. If channel disruption is
intermittent, it behooves us to “turn on” path redundancy and/or
Network Coding only when packet loss is severe. In this paper
we compare via simulation the performance of multipath routing
with and without Network Coding (and with/without dynamic
adaptation) for various motion and packet loss scenarios in terms
of reliability, efficiency, robustness, and scalability.
