Ad Hoc Network Routing Protocols:
ØLimited
radio transmission range and node mobility
nMany
Routing Protocols (literally 100s):
ØOn-demand: AODV, DSR
ØPro-Active: OLSR
ØHybrid: ZRP
nProblems:
ØMost
existing performance comparisons based on ideal propagation model (free space model, two-ray ground
model)
ØOur simulation results with shadowing model show severe performance degradation
