Abstract

The main goal of the Mobile Ad hoc Network is to seamlessly connect mobile devices
anywhere and at any time, and research in this field has become increasingly popular during
the last decade. Ultra Wideband technology has become a promising candidate to support
MANETs due to the large Band Width available and the high data rates achievable. Routing
protocols running within MANETs provide mobile hosts (or nodes) the ability to
communicate with each other; and the design of routing protocols has encouraged researchers
to investigate new strategies that establish connections.
The main aim of the research presented in this thesis was to design and implement an efficient
routing protocol for MANET based on the characteristics of UWB technology. The Location
Aided Routing protocol scheme 1 (LARI) was first considered in order to satisfy the
requirements of the proposed routing protocol which combines the advantages of the request
zone in LAR and the dynamic extended zones in the modified schemes of LAR. The key
objectives of this research were to reduce the power consumption of the mobile nodes and
thus increasing the lifetime of network, reduce the routing overhead, and increase route
reliability.
The software simulator QualNet was used to implement and test the modified protocol in
order to prove its efficiency. The resultant simulation was then compared with the simulated
results of existing routing protocols such as Ad hoc On Demand Distance Vector (AODV)
and LARI. Simulation results show that the new protocol outperforms both the AODV and
LARI protocols by increasing the network lifetime, reducing the routing overhead, and also
by providing the highest throughput. An analytical model was developed to prove the
correctness of the modified LARI protocol. This model determines the probability of finding
a valid node that receives the Route Request and can forward it to its neighbour nodes, this
represents the routing overhead of the protocol. In summary, it was found that the comparison
between the AODV, LARI, and the modified LARI routing protocols based on the analytical
model verifies the simulation results.
