Tactical Data Link (TDL) is a communication system that utilizes a particular message format and a protocol to transmit data via wireless channels in an instant, automatic, and secure way. So far, TDL has shown its excellence in military applications. Current TDL adopts a distributed architecture to enhance anti-destruction capacity. However, It still faces a problem of data inconsistency and thus cannot well support cooperation across multiple militarily domains. To tackle this problem, we propose to leverage blockchain to build an automatic and adaptive data transmission control scheme for TDL. It achieves automatic data transmission and realizes information consistency among different TDL entities. Besides, applying smart contracts based on blockchain further enables adjusting data transmission policies automatically. Security analysis and experimental results based on simulations illustrate the effectiveness and efficiency of our proposed scheme.

“…when and how to change the frame length, so a series of improved protocols are proposed based on USAP, e.g. ASAP (Dynamic TDMA Slot Assignment in Ad Hoc Networks) [5] and ADSAP (Adaptive-frame-based Dynamic Slot Assignment Protocol for Tactical Data Link System) [7]. ASAP improves the channel utilization by considering the autonomous behavior of nodes.…”

Tactical Data Link System always uses Time DivisionMultiple Access (TDMA) in Mac Layer. In TDMA, the channel is divided into time slots, and nodes are allocated slots to transmit data through the same time slot assignment algorithm. The tactical scenario is complicate and unpredictable, and some important messages need high Qos guarantee. It is hard to guarantee the Qos by the pre-allocated slot assignment protocol when the network is flooded, so Qos-based dynamic slot assignment protocol flourishes. But there is still a problem that low-priority message always suffers from starvation in these traditional Qos-based protocols. Thus, we propose a new Qosbased slot assignment protocol, which the frame length is changed dynamically according to the number of the requests in the network, to improve Qos performance of all kinds of messages. Through the simulation, we find that this protocol decreases the delay of messages of higher priority to some extent and obviously achieves desirable delay of the low priority message. Meanwhile, this protocol also improves the channel utilization.Key Words-tactical data link system; TDMA; slot assignment; quality of service (Qos); I.

Tactical data link (TDL) is a wireless communication system that achieves instant, accurate, automatic, and secure data transmission in military scenarios. It greatly reduces the time of Observation, Orientation, Decision, and Action (OODA). Modern TDL systems utilize a distributed architecture to enhance anti-destruction capacity and support data transmission among different TDLs. However, it is difficult to ensure data consistency among TDLs, which greatly reduces joint combat capacities of TDLs. A data transmission control system that can offer data consistency among various TDLs is highly expected. Besides, data transmission in TDLs should be controlled in an automatic and intelligent way to satisfy the low latency requirement of modern wars. To tackle this problem, in this paper, we employ blockchain-based smart contracts to build up a decentralized data transmission control system for TDLs called TDL-Chain. TDL-Chain achieves automatic data transmission and guarantees information consistency among various combat entities. The evaluation based on proof-of-concept implementation demonstrates the effectiveness and efficiency of TDL-Chain.
