Cellular ad-hoc relay for emergencies (CARE)
Anand A. Janefalkar, Kaushik Josiam, Dinesh Rajan · 2005
Emergency services are being improved by the Federal Communications Commission (FCC) by obligating wireless service providers to be E911 compliant by December 2005. We propose a system which is not only compliant with the E911 requirements, but also provides enhanced functionality to relay an emergency call arising from a user outside the cellular coverage area via another user within the range of the network. Simulations based on the GSM wireless technology are described and results show that cellular ad-hoc relay for emergencies (CARE) achieves a system efficiency of over 90%.
