"Monarch" Paper: A Performance Comparison of Multi-Hop Wireless Ad Hoc Network Routing Protocols 1998 Protocols compared are DSR,AODV,TORA,DSDV
Special Implementations: AODV-LL and DSDV-SQ
In this paper the performance is compared using the freely available ns2 network simulator.
Simulation Parameters (still need to find the ns2 simulation input files) (maybe here: ns2packets?)
- node mobility
- realistic physical layer
- radio network interface
- IEEE 802.11 MAC layer (with link breakage detection - except DSDV !!!)
Each node buffers 50 packets. The protocol buffers additional 50 packets.
50 nodes in a 1500m x 300m area. simulation time: 900 seconds pause time (nodes did not move): 0 - 900 seconds node speed: 1m/s - 10m/s (average) - 20m/s max.
Communication Aspects:
CBR sources: 10,20,30 packets delivered: 1,4,8 per second (!) packet size: 64byte,1024 byte (smaller than ethernet frame)
The paper discovered that sending packets/second is almost equivalent to the number of traffic sources. So they only simulate 4 packets per second.
The simulation was further restricted when they discovered that some nodes (1 or 2) drop almost all packets they received when using packet sizes of 1024 bytes (the density of the nodes might be one reason). So they reduce the packet size to 64 byte - because they wanted to test routing mechanics.
Another important fact: they dont use TCP sources because the packets are send with respect to the network load and that prevents a direct comparison.
Loser:
- DSDV at higher mobility
- TORA at high load
Winner:
- DSR
- AODV
In this paper the performance is compared using the freely available ns2 network simulator.
Winner:
- AODV
AODV vs.OLSR Paper 2004
In this paper network performance is compared on a theoretical base.
