Urban Monitoring Scenario
Problem Description
Design efficient summary harvesting protocols for mobile sensor platforms
Mobile storage
Sheer amount of data
Large scale
Non-intrusive
Scalable
Disruption tolerant
Challenges
Design Goals
Mobility Assist Summary Diffusion/Harvesting
Mobile agent (police) harvests summaries from its neighbors.
Agent uses a Bloom filter to find missing summaries.
Private nodes return summaries that the agents need.
Periodically relay one’s summary to k-hop neighbors
Listen and store received summaries.
Summaries are diffused through mobility.
Performance Evaluation
Metric: Harvesting latency for the mobile agent(s) to collect all summaries
Radio range vs. node density
Effect of node density (harvesting realization)
Effect of k-hop relay scope and multiple agents (harvesting realization)
