Routing in Mobile Ad Hoc NETworks (MANETs) is complex problem due to the dynamic topology, limited process and storing capability, bandwidth constraints, high bit error rate and lack of the central control. The design of efficient routing protocols is a fundamental problem in MANETs. Researchers have proposed a number of routing protocols in literature. Ants based routing is gaining more popularity because of its adaptive and dynamic nature. A number of Swarm Intelligence (SI) based, more specially Ant Colony Optimization (ACO) based routing algorithms are proposed by researchers. Each one is based on different characteristics and properties.
