The time synchronization is one of the main issues in frequency hopping mobile ad hoc networks (FH MANET) or time synchronous wireless sensor networks (TWSN). In the former case a network wide time reference is needed in FH code phase synchronization and in the latter case, e.g., in time stamping of the sensed phenomenon. Herein, a distributed decision making method (s) that solves the problems considering initial time synchronization, FH code phase synchronization, late-entry nodes and subnetwork merging cases of tactical FH MANETs and TWSNs is proposed. One of the starting points is a recently developed robust control channel method that enables the nodes to exchange the necessary synchronization messages prior the frequency hopping synchronism, i.e., out-of-phase. The proposed method is master free and based on node identifiers and local information that a node collects from the surroundings, namely local density and local data-activity. Simulation results are given that prove the functionality and the potentiality of the proposed methods.
