The authors investigate the cooperative routing problem in the single-source single-destination systems for the delay-sensitive case by using the proposed "Cooperative Graph" approach. The "Cooperative Graph" enumerates all possible cooperative routes in the problem. In a "Cooperative Graph", a vertex represents a route. For each route, optimal scheduling is required under a total end-to-end duration constraint. As a result, the "Minimum Energy Cooperative Route", which is the cooperative route with the minimum total energy consumption, can be obtained.
