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.
