Testbed Evaluation of a Delay Aware Routing Metric for Wireless Ad Hoc Networks

Free registration required

Executive Summary

Wireless ad hoc networks are a type of wireless network that is regarded as infrastructureless, dynamic and self-organising. To date, the challenges facing QoS in these networks have enjoyed much attention in simulation. To address this issue the authors practically implement enhancements on the Ad Hoc On-demand Distance Vector (AODV) routing protocol. They change the routing metric from hop count to measured end-to-end delay. The enhanced protocol, Delay Aware Ad Hoc On-demand Distance Vector (DA-AODV), will now be able to take the requirements of delay-sensitive services into account when selecting a route. They investigate whether the change of routing metric holds any real world benefit through experimental evaluation in a four node wireless prototype testbed.
