“…Moreover, in addition to using electromagnetic signals for communication, other communication media can also be used. For example, line-of-sight (LOS) based communication (by infrared or visible light) is a typical representative which is difficult to be interfered by the jammers [41]. This kind of new communication paradigm is very suitable for the communication between military units in the battlefield, e.g.…”

Wireless communications and networking are playing an important role in coordination and cooperation of multi-robot systems (MRS). However, it is challenging to keep a reliable and stable wireless connection in practical applications. Especially, robots acting in electromagnetic adversarial (EA) environments may encounter more serious situations including scarce spectrum, active interference, adversarial competition, etc. In this survey, we firstly analyze the challenges faced by MRS in EA environments, and provide a categorization according to the ''sense-decide-act'' robot control procedure. Secondly, enabling techniques for each challenge are introduced. Finally, typical robotics software architectures are introduced, as frameworks for efficient arrangement of the above mentioned enabling techniques.

“…Contribution of this paper: This paper is an extension to our previous work on visibility-based military unit formation [2]. We formulated the problem of validating whether the current configuration forms a valid connected network and proposed algorithms to compute a strategy to relocate a single vehicle to maintain LoS communication connectivity.…”

In communication-denied or contested environments, Line-of-Sight (LoS) communication (e.g free space optical communication using infrared or visible light) becomes one of the most reliable and efficient ways to send information between geographically scattered mobile units. In this paper, we consider the problem of planning optimal locations and trajectories for a group of autonomous vehicles to see a set of units that are dispersed in an environment with obstacles. The contributions of the paper are the following: 1) We propose centralized and distributed algorithms to verify that the vehicles and units form a connected network through LoS; 2) We present an algorithm that can maintain visibility-based connectivity, if possible, by relocating a single vehicle; and 3) We study the computational complexity of calculating the optimal positioning of multiple vehicles and propose an approximate geometric procedure to restore visibility-based connected network. Our ideas are implemented and tested through realistic computer simulations and outdoor physical experiments.
