A Bandwidth Study of a DHT in a Heterogeneous Environment

Olof Rensfelt and Lars-Åke Larzon

May 2007

We present a NS-2 implementation of a distributed hash table (DHT) modeled after Bamboo. NS-2 is used to evaluate the bandwidth costs involved in using a DHT in heterogeneous environments. Networks are modeled as mixed networks of desktop machines and 3G cellphones. We also document the modifications of NS-2 that were needed to simulate churn in large networks.
