Wireless Mesh Networks for Meteorological Monitoring

Wireless mesh networks can be used for various applications such as extending the coverage of wireless networks or connecting remote users to the Internet. By using wireless mesh networks for interconnecting meteorological weather stations to the Internet, multi-media sensor data can be observed in real-time. In such an application scenario, the wireless multi-hop network must fulfill high application requirements in terms of reliability, delay, and bandwidth. The exploitation of diversity mechanisms based on multiple paths seems to be a promising approach. The talk will present implementation experiences with wireless multi-path transmission and deployments of wireless mesh networks in out-door scenarios to interconnect remote weather stations with the Internet. Moreover, an evaluation and test environment for wireless mesh network implementations based on emulation and simulation to model realistic wireless channel conditions will be presented. The talk concludes with a discussion on how cognitive networking concepts can help to achieve the application requirements mentioned above.
