LightPS: Lightweight Content-Based Publish/Subscribe for Peer-to-Peer Systems

In this paper we present a technique for content-based publish/subscribe (pub/sub) systems that works without (distributed) explicit multicast group management. This technique, so-called LightPS, employs a rendezvous-based approach and, thus, maps subscription and event information into the peer-to-peer node Id keyspace. On the contrary to what could be expected, LightPS suits for high-dimensional pub/sub domains, requiring very low memory capacity and time to run subscription and event notification processes. We present its good performance through a formal theoretical analysis.
