Research on Emergency Communication Based on WMN

It is difficult to satisfy the increasing requirement of the emergency communicate for transmitting such as high-definition dynamic image, by the common communication network. By comparing the common traditional emergency communication network which is based satellite and trunking link and the emergency communication network which is based on wireless mesh network (WMN), an applied structure of network based on WMN is proposed. And the feasibility of the applied structure is analyzed and is verified by setting up an actual experimental testing environment. The applied emergency communicate network based on WMN has higher transmission rate, higher routing reliability and farther transmission range. The applied network based on WMN can satisfy the increasing requirement of the emergency communicate for transmitting such as high-definition dynamic image.
