A new geographical routing protocol for heterogeneous aircraft Ad Hoc Networks

Aircraft Ad Hoc Network is regarded as highly dynamic and sparse network because of high mobility, limited bandwidth and connection restrictions where nodes move in random fashion anywhere, which is different from terrestrial mobile ad hoc networks (MANETs), both in terms of network capability and underlying assumption. In such a highly dynamic environments the end-to-end communication between aircraft-to-aircraft is unique and serious challenge. To cope this problem we present a new geographical routing protocol for heterogeneous aircraft ad hoc networks (GHRAA), which is the extended version of Location Aided Routing (LAR) protocol. The main contribution of this geographic routing protocol is summarized as followings. 1) Primary path is established by using the known route information of the aircrafts, 2) Once the primary path is made, optimization path is reestablished by the aircrafts with arbitrary mobility pattern. Finally for simulation and analysis, we demonstrate high packet delivery ratio and short end-to-end delay in highly dynamic networks.
