  Abstract

In this paper, we propose a distributed TDMA (Time Division Multiple Access) scheme to reduce slot assignment delay and failure rate of tactical nodes in TURN (Tactical UAV Relay Network). Existing distributed TDMA schemes have a problem that slot assignment delays are large and failure rates are high. TURN is a multi-hop network in which the UAV relays tactical messages to all nodes. When existing schemes are used in TURN, there may be an absence of information about the adjacent node depending on whether the UAV slot is assignment, resulting in an increase in delay and failure rate. Therefore, this paper proposes URMA (UAV Relay-based Mutliple Access) scheme that provides low slot assignment delay and low failure rate in TURN environment. The performance of the proposed scheme is evaluated through simulation, and the results show lower slot assignment delay and failure rate than existing distributed TDMA schemes.
