Abstract

In this paper we investigate the DHT performance for Peer-to-peer SIP. We analyze performance from the mobile phone perspective. This angle brings battery consumption and efficient use of the limited resources of the mobile devices to the focus. We develop an analytical model of Kademlia DHT performance and use it to analyze a number of different strategies to use peer-to-peer SIP with mobile devices. These analyses include studying a model where all devices participate in the DHT and contrasting that with a model where only a subset of devices forms the DHT. Our analysis shows that in a one million user P2PSIP network, at least 30% of the mobile nodes should participate in operating the DHT to remain energy-efficient.
