MANET Routing

MANET
MANET: Mobile Ad hoc NETwork
mobile wireless network, capable of
autonomous operation
operates without base station
infrastructure
nodes cooperate to provide
connectivity
operates without centralized
administration
nodes cooperate to provide services
Applications
tactical (military) networks (FOI)
disaster recovery services
metropolitan/campus-area
communication networks (UU)
sensor networks (SICS)
enhanced cellular networks (KTH)
delay-tolerant networking (LUTH)
Design Choices
protocols fall into a few main categories
on-demand (reactive)
table-driven (pro-active)
ooding-based
cluster-based
geographic
application specic (cross-layer)
OLSR
Operation:
each node uses HELLO message to
calculate and announce its MPR set
a node sends link state information
only for nodes in its MS set (for which
it is an MPR)
each node processes (SPF routes) all
link state messages
a node only rebroadcasts link state
messages from nodes in its MS set
