Performance Evaluation of Service Searching using Aggregation in Peer-to-Peer Service Overlay Networks

Authors

Abstract

This paper presents a performance evaluation in
the context of the Aggregation Service (AgS). The AgS is a
P2P overlay-tier whose purpose is to aggregate the services and
service components maintained by service providers in a P2P
Service Overlay Network (SON). The performance evaluation
takes into account two metrics: 1) the average path length, and
2) the response time. Both of them are used in the comparison
of two environments: 1) AgS and 2) a P2P SON without AgS.
Additionally, the searching performance in the environment with
AgS is compared with a P2P SON that uses Gnutella as the
searching mechanism. The simulation results clearly show an
improvement in the performance of the search operations when
the AgS is used to the detriment of the searches performed
without it. The results also show AgS is better suited for use
in small overlays.
