Abstract:

In this article, a new distributed approach for scheduling in time division multiple access (TDMA) is proposed for aeronautical ad hoc network (AANET). AANET is a new sort of ad hoc networks whose nodes move fleetly and the corresponding topology changes rapidly. First, considering features of medium access control (MAC) protocols in the highly-dynamic aeronautical environment, we describe the criteria for a set of links to be able to transmit simultaneously with low interference lever at the receiving nodes and formulate the link-based optimal time slot assignment problem in spatial reuse TDMA (STDMA) with the goal of minimizing the average packet delay in the network. Then, we describe a new distributed approach for time slot assignment, named interference-based distributed TDMA algorithm (IDTA). Without the central control node, IDTA is divided into two processes at the sender and receiver respectively for a link and assigns the links with capacity proportional to their traffic load. Finally, a computer simulation model is implemented on the OMNeT++ platform and the result shows that IDTA is more suitable for the highly-dynamic aeronautical environment than other distributed STDMA algorithms.
