Abstract
The multimedia sensor network application has very high requirements for the end-to-end transmission delay. Meanwhile, due to limitation of sensor node resources, the energy consumption also becomes one of main problems in restricting the application development. Providing the low delay transmission capability for the multimedia sensor network by multipath routing is the effective solution, but also leads to many problems such as multipath generation and flow management. For this purpose, this paper designs the QoS-oriented multipath multimedia transmission planning (Q-MMTP), sets up the multipath routing generation algorithm with energy-delay balance by defining the new model of multipath transmission on the basis of traditional spline path generation planning, and generates a series of ideal routing paths uniformly distributed in space by the specified number of paths, delay requirements and node transmission power. In addition, this paper also designs the flow control planning on account of multipath routing, and redirects the flow of high load subflow to the lower load subflow by perceiving the throughput and energy consumption of each subflow, to ensure the overall throughput of the system. The test result indicates that Q-MMTP can effectively generate multiple routing paths and reduce the energy consumption to the greatest extent while ensuring the delay.
