Formatted abstract
Wireless Mesh Networks (WMNs) and wireless multi-hop networks in general have seen a tremendous development over the past couple of decades. Their independence from a wired backbone network, which allows relatively rapid and low cost deployment, combined with their self-configuring and self-healing capabilities and flexibility, make them suitable for deployment in a wide range of situations. These application scenarios include communications for rural communities, agriculture, natural disaster recovery, automatic (electrical) meter reading etc.

Routing protocols are a critical component for wireless multi-hop networks, and determine to a large extent the network performance. The problem is that current protocols are largely one-size-fits-all, and have a fixed set of protocol mechanisms and protocol parameters. This makes it impossible for these protocols to perform equally well in all the possible deployment scenarios, under very different network characteristics, such as network size, network topology, level of node mobility and traffic patterns.

To address this shortcoming, this thesis explores how wireless multi-hop routing protocols can be adapted and tailored towards their specific deployment scenario. Towards this goal, the thesis explores the impact of choosing specific protocol mechanisms and protocol parameters on the performance of wireless multi-hop networks, under different network scenarios. The thesis further presents a new hybrid protocol, which combines end-to-end routing of traditional wireless mobile ad-hoc and networks, with the store-carry-forward routing paradigm of Delay Tolerant Networks (DTNs). An extensive evaluation over a wide range topologies, from highly connected to highly disconnected, shows that this protocol can significantly improve the performance in most cases.
