Title: 100% Certified Organic: Design and Implementation of Self-Sustaining Cellular Networks Abstract: A fundamentally new method for deploying cellular networks is emerging in the market in which customers deploy the network themselves. One approach to drastically reduce the cost of these customer-installed networks is to design self-supportive organic networks which implement all of the services and management necessary without support from a core network or central planning. Through the design and implementation of of two essential services, authentication and location registration, we demonstrate effective service design and management in the organic network. We also outline the challenges for management of the organic network itself.
