| Within this thesis, the problem of device and sensor communication is discussed. Recent sensor network implementations and deployments at the University of Iowa IIHR-Hydroscience and Engineering (IIHR) and the Iowa Flood Center (IFC) have motivated the need for an efficient, shared, 1-wire communication scheme. Possible solutions will be explored and discussed briefly within this chapter. The focus of this thesis is the development of a particular solution for a 1-wire physical layer utilizing the concept of Code Division Multiple Access (CDMA). |
