A node cooperation based random linear network coding algorithm for wireless sensor networks

In order to enhance the resources limited wireless sensor network the volume of throughout and the transmission reliability, the paper introduce the multicast routing network code technology to the unicast routing wireless sensor network. In this foundation, the time delay and the energy expenses which will bring to the stochastic linear network code makes the improvement through the node cooperation. The simulation result indicated that, compares with the opportunity route data transmission method, the cooperation network code strategy full use space and time reusability, reduced the data transmission time delay, enhanced the wireless sensor network volume of throughout.
