An enhancement for DH-AODV routing protocol by using local route repair

Wireless Mesh Networks (WMNs) might be the most important wireless network in the future as a key technology. However, WMNs has not met our expectations. Thereby, several researches focused on this field to specify the issues that needs to be solved. Based on the researches, one of the most important factors in WMNs is the routing protocol and how it makes it more efficient to transmit the data over the nodes. This paper aims to enhance a routing protocol for WMNs to improve the performance of data transmission and receive better energy save while transmitting the data. The Directional Hierarchical Ad hoc On Demand Distance Vector (DH-AODV) routing protocol has been selected in this research which is an improvement of Ad hoc On Demand Distance Vector (AODV) routing protocol in case of route breakage and network quality. DH-AODV is efficient routing protocol for WMNs and performing well, but they have not considered a mechanism to find new node when link fails and the next node is unreachable. To handle this problem, DH-AODV will be modified by using Local Route Repair (LRR) in order to achieve better energy save while transmitting data and less End-to-End (E2E) delay.
