Abstract

Wireless Mobile Ad-hoc networks (MANET) require dynamic routing schemes for adequate performance. In this paper, we introduce a new dynamic routing scheme based upon stigmergy. In a similar manner to ant-colony based dynamic routing protocols, our scheme is able to respond to link quality changes after a path is established. However, load balancing is not obtained through probabilistic routing (as in ant-colony based protocols) but through the exploitation of available information on forwarding choices by intermediate nodes. We present the results obtained from an NS-2 testbed, in which performance comparisons with AODV and Ant-Colony based protocols are highly promising.
