An Improved Byzantine Fault-tolerant Program for WSNs

In order to increase the level of fault-tolerance of wireless sensor networks, thus to enhance the reliability and accuracy, we studies the traditional byzantine fault-tolerant program, and makes improvements in the environment of WSNs, reducing the number of rounds of message exchange between network nodes, thus improving the efficiency and reducing communication overhead and energy consumption. The simulation result shows that our program makes all normal network nodes reach an agreement, while the number of rounds of message exchange greatly decreases compared to the traditional byzantine program.
