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