8.1 CHALLENGES IN EMPIRICAL EVALUATION OF P2P ALGORITHMS

Due to the decentralized nature and fast growth of today’s P2P networks, testing P2P algorithms in a real-world environment by simply deploying them on an existing P2P network and collecting data on their performance is a daunting task. In some cases, measurements are easier to carry out due to some easily accessible central control entity in the network that manages node joins and departures [71]. Also, some algorithms may be tested by deploying them on one or a few controlled nodes in the network (as in [74]). However, for a wide range of P2P-related ...
