Abstract(in English) | With rapid increases in demand for mobile data, mobile network operators are trying to expand wireless network capacity by deploying wireless local area network (LAN) hotspots to offload their mobile traffic. However, these network-centric methods usually do not fulfil interests of mobile users (MUs). MUs consider many problems to decide whether to offload their traffic to a complementary wireless LAN. Our previous work studied a single-flow wireless LAN offloading problem from MU's perspective by considering delay-tolerance of traffic, monetary cost and energy consumption. In this paper, we study a multi-flow mobile data offloading problem in which a MU has multiple applications to transmit data simultaneously with different deadlines. We formulate the wireless LAN offloading problem as a finite-horizon discrete-time Markov decision process (MDP) and propose a dynamic programming based offloading algorithm. Since time complexity of the dynamic programming based offloading algorithm is rather high, we then propose a low time complexity heuristic offloading algorithm. Extensive simulations are conducted to validate our proposed offloading algorithms. |
