Swarm robotics, inspired by the collective behaviors observed in various biological systems, has emerged as a transformative field for achieving complex tasks through the collaboration of multiple robots. This chapter delves into the pivotal role of communication strategies within swarm robotics systems, drawing parallels from the efficient information exchange observed in natural swarms. At its core, the investigation unfolds decentralized communication protocols, encompassing both direct and indirect methods that robotic swarms utilize for seamless information sharing. The concept of stigmergy takes center stage, where communication occurs through the modification of the environment by individual robots, fostering a decentralized yet coherent approach to task execution.
