EARTHQUAKE EARLY WARNING SYSTEM IN THE WESTERN HIMALAYAN REGION OF INDIA: AN ARCHITECTURAL DESIGN USING THE BotRf SIMULATION TOOL
Main Article Content
Abstract
We present a Long distance Wi-Fi based architectural design for an early earthquake warning system using the BotRf Telegram simulation tool for wireless links design. In this paper, a dedicated bidirectional communication ring connecting three locations within Himachal Pradesh state with a ring topology is proposed. This topology allows for redundancy to transport the signal to the earthquake monitoring centres by two independent routes, a direct one and another using an intermediate site as a repeater point. Being a dedicated ring, not part of the commercial Internet, it is not affected by commercial traffic during and after an earthquake. Even in case of disrupted service of the existing commercial communications networks, as often happens after a seismic event, the proposed network would still operate since it will be autonomously powered by means of solar panels and batteries. Therefore, the seismic data will be delivered to the emergency offices that can effectively react with the proper measures. The functional architectural design testbed for early earthquake warning (EEW) system would be available in the western Himalayan Region of India constituting a major step to improve earthquake monitoring alertness in this region.
