Performance Assessment of a New Routing Protocol in AANET

Routing is a critical issue in mobile ad hoc networks. The routing algorithm must take into account the specific properties of the network such as its topology, the mobility of the nodes and their number. In this paper, we present a simulation-based study of the performances of our innovative routing protocol named NoDe-TBR (Node Density TBR) that takes into account the actual node density distribution. The considered ad hoc network is an Aeronautical Ad hoc NETwork (AANET), a future communication system enabling air↔air and air↔ground communications beyond the radio range of the sender. This context and the communication architecture have been modeled in a realistic way based on replayed aircraft trajectories, a realistic access layer, and application that should be deployed in the future

Routing protocol assessment for AANETs

In this paper, we propose to use AANETs (Aeronautical Ad-hoc NETworks) to complement currently used communication systems. An AANET is a network in which every node (aircraft or ground station) is able to relay data to and from other nodes. It allows to extend the range of a ground station by using other aircraft as relays, thus establishing multihops paths between an aircraft and the ground. The main contribution of our study is the performance assessment of classic routing protocols by simulation with replayed real aircraft trajectories. The results of these simulations can serve as reference for further studies. Furthermore, under nominal conditions, AODV has the best performances in terms of reachability. These results demonstrates the interest of AANET as a communication system for civil aviation, and call for further studies to improve the performances of routing algorithms
