Ad
hoc Routing Protocols
nRouting problem has
received a significant interest in the research community, resulting
in several protocols proposed.
–Some have been invented specifically for MANET.
–Others are adapted from traditional routing protocols for wired networks (i.e., distance
vector or link state algorithms)
nThese traditional
protocols do not work efficiently or fail completely.
nThe main group of
proposals comes from the work of IETF’s MANET working group
–Designed for IP based, homogeneous, mobile ad hoc networks.
–Focuses on fast route establishment and maintenance with minimal overhead
nNumber of hops is
used as the only route selection criteria.
nOther parameters,
such as energy usage or QoS, are not considered.
