Abstract: The impact of the peer-to-peer paradigm increases both in research and in industry. Still, serious applications for P2P-based systems are rare. On the other hand, Emergency Call Handling (ECH) is (or will be) a mandatory function for VoIP services. In this paper we investigate interna- tional legal and technical requirements of ECH and present ECHoP2P, a solution that fulfills these requirements. Based on Globase.KOM and HiPNOS.KOM, ECHoP2P provides the functionality to determine the closest and (geographi- cally) responsible Emergency Station to a calling peer. Fur- ther, Emergency Calls are processed with highest priority in the overlay, so that quality of service guarantees are given. We evaluated ECHoP2P thoroughly and present the qual- ity and costs analysis, identified tradeoffs and effects of op- timization parameters. ECHoP2P provides a fully evalu- ated solution for Emergency Call Handling and for further location-aware applications.
