Integrating Administrative Records into HUD's Housing Surveys
This presentation by Shawn Bucholtz delves into the integration of administrative records and commercial data sources into HUD's housing surveys, exploring past achievements, current practices, and future strategies. The process involves merging federal and state administrative data, local administrative data, commercial data, and other geospatial data to enhance the accuracy and relevance of housing surveys. The research addresses challenges faced in microdata integration to improve data quality and completeness.

Definition for Definition for IoT IoT island island Local networks of IoT devices operating in disconnected modes (are isolated with outside network) due to the loss of network infrastructures to achieve the connectivity to data processing center or cloud platforms. Objective and solution Objective and solution -> Objective : Transmitting sensing data to the network access points ( data upload point) . -> Solution : Deploying data upload points into IoT island which can cover all monitoring area. -> Optimization : Minimizing the cost of the upload point deployment within delay tolerance threshold.
Chara Charac cteristics of teristics of o our working scenario ur working scenario Sensors are deployed in certain area. Clustering method : rendezvous-based approach, in which mobile sink can communicate the rendezvous point directly. The routes and the schedules of buses are predefined. Mounting the data collector on the public buses which act as the mobile sinks.
Setting simulation Setting simulation 1. Simulating the routes of mobile sinks (based on real bus routes). 2. Sensor clustering using Rendezvous-based approach. 3. Mobile sinks gathering data from RPs. 4. Mobile sinks upload data to upload point ( network access point ).
