[Abstract] There are a number of issues in large-scale wireless sensor networks because of environmental interference and a scarcity of system resources. Issues include imbalances between sensing and delivering, ability and demand, and theory and practice. In this paper, recommendations are made for a network framework, system architecture, and data forwarding in sparse networks. We also give a brief introduction to simulation and testing technologies for large-scale networks.
