Routing: Open Problems
n Mobile Ad Hoc Network Routing Protocols:
Ø Limited radio transmission range and node mobility
n Many Routing Protocols (literally 100s):
Ø On-demand: AODV, DSR
Ø Pro-Active: OLSR
Ø Hybrid: ZRP
n Problems:
Ø Most existing performance comparisons based on ideal
propagation model (free space model, two-ray ground model)
Ø Our simulation results with shadowing model show severe
performance degradation
