How to Discover Optimal Routes in Wireless Multihop Networks [chapter]

Michael Gerharz, Christian de Waal, Peter Martini
2005 IFIP International Federation for Information Processing  
In this paper, we introduce a distributed algorithm that is able to discover optimal routes in mobile wireless multihop networks using reactive routing protocols.  ...  The algorithm is based on Dijkstra's shortest-path algorithm and maps the quality of a path to a delay of the corresponding route request to allow highquality paths to surpass low-quality paths.  ...  There are several requirements to an algorithm supposed to discover optimal routes according to some routing metric.  ...
