This paper presents the state of the art in biologically inspired ant based routing in wireless Mobile Ad hoc NETworks (MANET). The motivation for using ant-like mobile agents for providing routing information to mobile hosts in MANETs stems from the fact that ant-like mobile agents do not require high bandwidth overhead compared to MANET proactive routing protocols for disseminating the topology information in the network. The increased connectivity information provided by the ants can be used to for making better routing decisions which can improve the network performance without causing high overhead.
