MANET Routing Protocols
w Main Characteristics of MANET
n Multi-hop to the destination
n Dynamic topology due to node mobility, interference, ….
n Limited resources: wireless bandwidth, battery…
Challenge: routing overhead vs. accuracy of network
information (in particular dynamic info)
w Limitations of existing routing protocols
n Static and universal routing parameters (i.e., RFC 3626 recommends
for OLSR: 2 second HELLO interval, 5 second TC interval)
n Problems: what are right values, should all nodes have same
parameter values all the time?
