We study the rendezvous search problem for k ≥ 2 mobile agents in an n node ring. Rather than using randomized algorithms or different deterministic algorithms to break the symmetry that often arises in this problem, we investigate how the mobile agents can use identical stationary tokens to break symmetry and solve the rendezvous problem. After deriving the conditions under which identical stationary tokens can be used to break symmetry, we present several solutions to the rendezvous search problem. We derive the lower bounds of the memory required for mobile agent rendezvous and discuss the relationship between rendezvous and leader election for mobile agents.
