Key Considerations for Planning an Optimised MANET for Seamless TAK Server Deployment in Tactical Networks
In tactical environments, where flexibility, real-time communication and interoperability are of paramount importance, MANETs play a crucial role. The integration of TAK (Tactical Assault Kit) servers into MANETs plays an essential role providing real-time data exchange, video streaming, GPS tracking and other situational awareness data. However, even though MANETs provide an agile network there are unique challenges that are presented; that require careful planning and consideration. This article outlines some of the key factors to consider during the initial planning phases of a tactical MANET deployment to ensure effective TAK server and ATAK integration.
Defining mission objectives
The foundation of any successful MANET deployment begins with clearly defined mission objectives. When planning a MANET deployment, it’s crucial to outline the specific requirements for situational awareness data, which is integral to TAK functionality. This means that the network must not only be designed to accommodate the original number of end users, but must also be capable of scaling to accommodate a larger number of end users. The network must also be able to handle the high data load and latency requirements of TAK, especially high-pressure environments, where decisions can be based heavily off of data provided by the TAK system. Failing to align the network’s capabilities with the mission objectives could result in compromised situational awareness, which could result in severe consequences.
Network size and scalability
Another critical factor in the planning phase of a MANET deployment, is determining the network size and ensuring scalability. The nature of a MANET allows for the adding and removal of nodes within the network. However, TAK servers need to support a varying number of connected end users, from a few individuals in a small-scale operation, to potentially hundreds in larger missions. The network must be designed with scalability in mind to accommodate additional nodes without degrading the performance of TAK services. This includes considering the routing protocols that will be used, as they must efficiently handle the dynamic and ever changing topology of a MANET, whilst ensuring timely updates and maintaining situational awareness. The ability of the network to scale impacts the TAK server’s ability to provide updates containing valuable mission data.
Bandwidth and data throughput planning
In a MANET, bandwidth is extremely limited and is a valuable resource that must be carefully managed. Effective bandwidth and data throughput planning is essential to avoid bottlenecks that could disrupt communication. Mobile nodes within a MANET communicate through wireless channels that are bandwidth-constrained and have variable capacity. These wireless links offer significantly lower capacity compared to wired connections, making congestion management a greater challenge. Estimating the expected traffic based on the number of TAK clients and their real-time data exchange needs (live maps, video streaming etc), is a crucial step in the planning process. Once traffic has been estimated, planners must design the network to allocate bandwidth efficiently and implement load balancing across the nodes in the network. This ensures that all users receive the data they need without overwhelming any single point in the network. Failure to plan for bandwidth and data throughput can lead to significant delays in data transmission, which could be catastrophic in a tactical situation where situational awareness is compromised.
TAK Server specific considerations
The TAK server(s) itself, requires additional consideration, particularly in terms of load and scalability. Evaluating the server’s ability to handle a high number of concurrent users and data requests is essential. Depending on the mission and the different use cases, it may be necessary to plan for horizontal or vertical scaling of the server. Horizontal scaling involves adding additional TAK servers to handle the load or to use in different missions/situations. While vertical scaling would involve upgrading the existing servers hardware, such as the machine that the server is hosted on. Additionally, redundancy and failover mechanisms must be planned to avoid a single point of failure. This means ensuring that backup servers are available and are capable of seamlessly managing the traffic and having the correctly configured user groups.
Architectural design and security considerations
The architectural design and topology of the MANET are also critical elements to consider. The choice of routing protocols can significantly impact network performance. Protocols must be selected based on their ability to support dynamic and scalable networks. Additionally, the overall topology must be designed to ensure optimal connectivity and communication flow.
Authentication mechanisms play a key role in securing the network. Implementation of a Public Key Infrastructure (PKI) framework that uses digital certificates to authenticate nodes within the MANET is an effective strategy. Furthermore, disabling the root user account on the server (post setup) once a dedicated superuser has been created, changing the default SSH port, and securing client certificates by moving them offline are all important security measures that can help to protect the network from any unwanted access.
Summary
Planning a MANET for seamless TAK server integration requires careful consideration of mission objectives, network size, scalability, bandwidth and security. By addressing these factors in the planning phase, you can ensure that your MANET is robust, scalable and secure, providing reliable real-time data exchange and situational awareness in a tactical environment.
