Objectives
- Evaluate performance and scalability of the DHT implementation (Latency, Bandwith, Startup latency, Changes in the network structure)
- Comparation between DHT and traditional approaches (Flooding)
- Difference in fulfilling a request
- Difference in startup latency
- Comparation between simulation and experimental results
Measurement Plan
Influence Factors
- Size of the (core BRN) network in number of nodes
- Number of clients (TODO absolute or per BRN node)
- Changes in the network structure
- TODO Charater of requests?
- TODO Amount of stored data (number of DHT keys)?
Measurement Values
- Response time of an request (DHT/ARP/DHCP)
- Used bandwidth for fulfilling a request (number of packets or bytes?)
Constants during Measurement
- Only 1 request at a time
Measurement: Latency
- Variable number of nodes n
- Only on client
- Measure time for fulfilling a request for DHT and Flooding
Measurement: Bandwidth
Measurement: Startup Latency
Measurement: Dynamic Changes in the Structure of the Network
- Measure time for reorganization
