· A Peer-to-Peer (P2P) network can boost its performance if peers are provided with underlying network-layer routing topology. The task of inferring the network-layer routing topology and link performance from an end host to a set of other hosts is termed as network tomography, and it normally requires host computers to send probing

Peer-to-peer (P2P) networks enable the interconnection of a huge amount of information sources without imposing costs for a central coordination infrastructure. Due to the dynamic and self-organizing nature of such networks, it is not feasible to guarantee completeness and correctness as in traditional distributed databases.

The main challenge in P2P approximate query processing is to select the optimal subset of peers to which the query is forwarded. However, the selection criteria for this subset are completely different for top-k and aggregate queries.While in top-k the goal is to identify the peers holding top objects, approximate aggregate querying algorithms need to find a

Abstract. In peer-to-peer (P2P) networks, flooding-based resource discovery is very popular. With flooding, a node searching for a resource contacts its neighbors in the system, which in turn contact their own neighbors and so on until a node that shares the requested resource is located. Flooding process assumes no knowledge about the network
