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 and structural change 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
