In this paper, we explore the use of wireless mesh networks (WMN) for the purpose of exchanging GPS raw data to support in-network processing of low-cost GPS devices. A proof of concept deployment with a small number of GPS stations is studied. This experiment validates the feasibility of using WMN to enable in-network processing in a dense GPS network.(More)
In this paper, we explore the use of wireless mesh networks (WMN) for the purpose of exchanging GPS raw data within GPS stations in a WMN to support real-time in-network processing of low-cost single-frequency GPS devices. A proof of concept deployment with a small number of GPS stations was studied. This experiment validates the feasibility of using WMN to(More)
In this paper, the use of mesh networking for the Sumatran continuous-Global Positioning System Array (SuGAr) was proposed to optimize the telemetry between the nodes in the array and a centralized remote data server. Currently, data from the array is transferred directly to the data server via dedicated satellite links from each node in the array. This(More)
In recent years, tectonic plate movements have caused huge natural disasters, such as the Great Sumatra-Andaman earthquake and the resulting Asian tsunami, which led to significant loss of human lives and properties (Ammon et al., 2005; Lay et al., 2005). Scientific evidences proved it was the beginning of a new earthquake supper-cycle in this active area(More)
