Routing
Protocols and Simulation Environment
nRouting Protocols:
ØAODV: on-demand protocol with traditional routing
tables
ØDSR: source routing, route caches, nodes (optionally)
listen promiscuously to learn
information to update cache
ØTORA: link reversal algorithm, maintains enough info so
that link failure not necessarily
results in new route discovery, more complex
control messages
nSimulation Environment: “the usual”
ØNS2, 50 nodes, 1500 x 300 m, initial power: 1000
Joules
ØCBR sources, 5 packets/s, 512 byte packets, 12
senders
ØRandom waypoint model, 20 m/s max speed, variable pause
time
Ø600 seconds simulation length, 4 different movement
patterns per scenario
