Abstract: In-network computation can greatly reduce the traffic generated during many-to-one transmission by establishing aggregation trees to merge data streams at the aggregation nodes. In this paper, we consider finding the minimum-cost aggregation tree under the constraints of given amount of resource and the capacity of switch nodes. Since this problem is a NP-hard problem, a linear integer linear programming model and a heuristic algorithm called GCAT are given to solve it. Simulation results show that the GCAT algorithm can generate a tree with less cost and utilize the resource more efficiently compared with other heuristics, and the performance is close to the optimal solution for small-scale networks.
