Information monitoring system, conjunctive query,, continual query.


In this paper, we propose a method to efficiently sup port conjunctive queries in P2P information monitor ing systems, based on the notion of new agent called Conjunctive Continual Queries (CCQs). More con cretely, we propose a new scheme to assign CCQs to peers. The basic idea of the scheme is to use a cluster ing of CCQs. The result of simulations indicates that: 1) it realizes a graceful degradation of the performance as increasing the number of CCQs, and 2) the imbal ance of load of peers could be efficiently bounded.
