Motivation

•Optimize power•Optimize longevity•Optimize transmission efficiency

Research Methodology

•Trial and error: spokes

Findings

• Good data storage is hierarchical

Today Yesterday Last week

• Good network topology is also hierarchical

Conclusion

• Wireless sensor research is ongoing, but Ganesan’s work is worth looking into
