Design and implementation of one redundancy function in wireless tree networks

Communication reliability has always been the bottleneck problem for wireless networks. Combining with the development of wireless networks for emergency application, a new approach is proposed to implement the redundancy function in wireless tree network. The necessity of this approach is analyzed, the whole system includes software and hardware is designed, the significative experiment is completed that shows this approach effectively ensures the communication reliability of wireless tree network and the whole network possesses the functions of redundancy and self-healing.
