PERFORMANCE OF WIRELESS AD HOC NETWORKS

A wireless ad hoc network is a dynamic network
formed on demand by a group of
terminals without the aid of any pre-existing
infrastructure. In ad hoc networks messages
are often relayed from source nodes to destination nodes along multi hops. This multihop
transmission improves the spatial concurrency of the
network, but on the other side
it deteriorates the multi-hop burden. Therefore, the
network throughput per user decays
with the increment of the number of users. This
dissertation incorporates the Multi User
Detection (MUD) technique into ad hoc networks to
further increase the spatial concurrency
by supporting Multiple Packet Reception (MPR). It
presents a thorough study on
network throughput via both analytical and
simulation approaches.

Additionally, terminals in ad hoc networks are often
power supplied with limited battery
capacity, which necessitates energy conservative
routing protocols to prolong the
network lifetime. This dissertation also addressed
this energy conservation problem by
proposing energy-aware and link-adaptive routing
metrics for ad hoc network routing.
