Description: Wireless Mesh Networks (WMNs) can be the key technology for future wireless network. However, WMNs implementation still has many issues to be resolved especially on finding the best path to forward information. According to many researches, one of the most important component in WMNs is the routing protocol and how to make it efficient in performing the requirements of WMNs. This research proposes to improve the route discovery and route breakage by introducing new mechanism in Directional Hierarchical Ad-hoc On-demand Distance Vector (DH-AODV) routing protocol. In order to meet the WMNs routing requirement for path selection, all of the factors of data transmission to achieve an efficient routing protocol are considered. The main aim of this research is to enhance DH-AODV routing protocol by implementing proper criteria that can improve the performance of this protocol. DH-AODV does not consider the energy consumption and the buffer status of each node in the network. Furthermore, a method to deal with route failure is also not considered, where link failure is frequent in this network. In this research, we propose three criteria called Buffer mode as indicator for traffic conditions, energy mode to define the energy level of each node and Local Route Repair (LRR) to re-establish path whenever link breakage happen. Our proposed routing protocol is called User Preference Directional Hierarchical Ad-hoc On-demand Distance Vector (UP-DH-AODV). UP-DH-AODV is proposed based on the user preference to choose one of the three criteria that can fully meet the user network requirements. The results show that we have improved the overhead by 26%, and the PDR by 42%, as well as reducing the energy consumption to 10% by using the buffer mode. Where in the energy mode we have improved the PDR by 18% and reduced the energy consumption by 31%. Finally, we have reduced the energy consumption by 29%, and improved the PDR to 19% by using the LRR mechanism.,Certification of Master's/Doctoral Thesis" is not available
