Sahana HF data platform for alert and situation reports

On my way to the IDRC meeting in Penang I spent two days with Prof. Ahmad Zuri et al in Cyberjaya, Malaysia evaluating the Sahana Common Alerting Protocol (CAP) messaging over HF spectrum data platform. Prof. Zuri's team through, a grant from the Malaysia Communications and Multimedia Commission (MCMC) and the support from Mr. Zolkhonain Norizan and Mohd Aris Bernawi of MCMC, a prototype of the transport and application layers were developed by June 2009.

The lab setup was replicated at MCMC with two HF radios connected to two laptops through Pactor II modems; one acting as the remote client and the other as the IP-HF gateway transforming the HF data to the Internet. A third laptop was hosting Sahana on the LAMP stack. A CAP message sent through Sahana could is first received by the IP-HF gateway, which resolves the string and relays it to the remote station transported as HF data.

Other than a few flood incidences, Malaysia (MY) is perhaps one of the least disaster prone country in the Asia-Pacific. With that in mind, the idea is to setup a hub in MY to transport Sahana specific emergency information through the HF spectrum. As of now, Maldives, Malaysia, and Sri Lanka have agreed to pilot this system. We await hope a Pacific Island or New Zealand may join the consortium. Proposal is in the working to seek funding.
