| Summary: | There are real-time transmission problem of multimedia data and network lifetime optimization problem in wireless multimedia sensor networks. In order to solve the problems, multi-path routing algorithm based on minimum cost maximum flow（MRAMCMF）was proposed. MRAMCMF analyzed energy consumption of data transmission, node remaining energy and minimum data transmission delay, proposed a new weighting function, and used the minimum cost maximum flow algorithm to construct the multi-path routing scheme. All multimedia sensor nodes transmited data to sink node along the paths. Simulation results show that MRAMCMF can prolong network lifetime, reduce and balance node energy consumption, and reduce data transmission delay. Under certain conditions, MRAMCMF outperforms Ratio_w and TPGF. |
