This work proposes a method for allocating temporally interdependent tasks to homogeneous or heterogeneous cooperative agents in dynamic large-scale networks. This method views searching, task allocation and scheduling as an integrated problem that has to be efficiently solved in such networks. Solving the general problem optimally in a decentralized way is very hard and can only be solved by a centralized method, be approximated by means of heuristics, or by relaxations of the original problem. Our method facilitates effective searching through the dynamic assignment of gateway roles to agents and the exploitation of routing indices. In combination to searching, it exploits distributed constraint satisfaction techniques and dynamic re-organization of agent teams to efficiently handle the allocation of complex tasks with interdependent subtasks.
