With the expansion of wireless technologies, the ad-hoc networking between aircraft has become possible. This kind of networks is known as Airborne Ad hoc Networks (AANETs). These networks have emerged as one of the highly challenging areas of research due to the unique flight dynamics of the aircraft being used as nodes. The cruising speed of an aircraft (around 400-500 mph) is the major reason behind the intermittent link quality between two communicating aircraft. As a result, the routing between aircraft has emerged as a major threat for research in this field. This paper presents a study of different routing solutions provided recently by the research community for AANETs. A simulation analysis of the two well-known routing protocols i.e. OLSR and GPSR has also been provided here to identify their suitability in the airborne environment.
