An energy optimization scheme based on rate guarantee in emergency mesh network

The wireless mesh network (WMN) is effective emergency networks in disaster area which has a flexible network topology. The efficiency of the energy is particularly important in the emergency communication network. In paper, we proposed an energy optimization scheme based on framework of wireless mesh networks. This scheme ensures rate achieved under the condition of the original transmission power in the wireless mesh network, by reducing mutual interference between nodes to make the transmission power of the nodes down, thus extends the lifespan of emergency network effectively. A number of simulation results show that the proposed scheme can reduce the transmission power of nodes while ensuring the end-to-end data rates.
