The three most commonly used MANET routing protocols are DSDV, AODV and OLSR. The following benchmarks compare these protocols to the OrderOne Networks mesh network routing protocol at network sizes between 50 and 300 nodes.
All Nodes are moving randomly at a velocity versus radio range that is equivalent to:
- A fast walking pace carrying an 802.11 radio
- A vehicle driving at 60mph with a 3 mile radio range
- A commercial jet aircraft with a 27 mile radio range
Network density is constant as the network size varies between 50 and 300 nodes. A moderate to high network load is provided by 80 constant bitrate (CBR) data flows.
The simulator was ns2 v2.34. The AODV and DSDV protocols were provided with ns2 and the OLSR protocol was UM-OLSR 0.8.8. These are the most recent versions available and are configured using their default parameters.
Delivery ratio, latency and control bandwidth overhead for each of these protocols at different network sizes were gathered.
The OrderOne Networks MANET routing protocol is able to maintain a high packet delivery ratio as the network size increases.The OrderOne Networks MANET routing protocol is almost unaffected by network size.
Packet latency is extremely important when a network is moving voice or video data. Regardless of network size the OrderOne Networks routing protocol finds the best route to minimize latency.
Control bandwidth for the other routing protocols can grow exponentially with network size. In these sets of tests the OrderOne Networks MANET control bandwidth was configured to never exceed 2.12Kbps. At the smaller network sizes even this modest allocation was not required.
The OrderOne Networks Mesh Network Routing Protocol provides superior packet delivery ratio and latency at a fraction of the control bandwidth. The amount of control bandwidth that is used by the OrderOne Networks protocol may be set at any level by the Integrator.
Comparison to OSPFv3-MANET
This routing protocol is currently being pursued by the IETF working group responsible for adding MANET extensions to OSPF. In these tests the OrderOne Networks protocol required 8x - 20x less bandwidth to achieve the same performance as OSPFv3 MANET. When the OrderOne Networks protocol was allowed more bandwidth it was generally able to deliver 20% - 50% more packets.
The OrderOne Networks protocol clearly outperforms these other available routing protocols. A cost free evaluation license is available to allow potential licensees the ability to perform their own analysis.
