Such algorithms exploit the properties of\n                    <jats:italic>swarm<\/jats:italic>\n                    systems, in which a number of entities\/agents perform simple operations at the local level, but together engender an advanced form of\n                    <jats:italic>swarm intelligence<\/jats:italic>\n                    at the global level. In particular, So-Grid provides two main functionalities: logical reorganization of resources, inspired by the behavior of some species of ants and termites that move and collect items within their environment, and resource discovery, inspired by the mechanisms through which ants searching for food sources are able to follow the pheromone traces left by other ants. These functionalities are correlated, since an intelligent dissemination can facilitate discovery. In the Grid environment, a number of ant-like agents autonomously travel the Grid through P2P interconnections and use biased probability functions to: (i) replicate resource descriptors in order to favor resource discovery; (ii) collect resource descriptors with similar characteristics in nearby Grid hosts; (iii) foster the dissemination of descriptors corresponding to\n                    <jats:italic>fresh<\/jats:italic>\n                    (recently updated) resources and to resources having high quality of service (QoS) characteristics. Simulation analysis shows that the So-Grid replication algorithm is capable of reducing the entropy of the system and efficiently disseminating content. Moreover, as descriptors are progressively reorganized and replicated, the So-Grid discovery algorithm allows users to reach Grid hosts that store information about a larger number of useful resources in a shorter amount of time. The proposed approach features characteristics, including self-organization, scalability and adaptivity, which make it useful for a dynamic and partially unreliable distributed system.\n                  <\/jats:p>","DOI":"10.1145\/1352789.1352790","type":"journal-article","created":{"date-parts":[[2008,5,28]],"date-time":"2008-05-28T08:21:21Z","timestamp":1211962881000},"page":"1-37","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":24,"title":["So-Grid"],"prefix":"10.1145","volume":"3","author":[{"given":"Agostino","family":"Forestiero","sequence":"first","affiliation":[{"name":"Institute for High Performance Computing and Networking (ICAR-CNR)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlo","family":"Mastroianni","sequence":"additional","affiliation":[{"name":"Institute for High Performance Computing and Networking (ICAR-CNR)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giandomenico","family":"Spezzano","sequence":"additional","affiliation":[{"name":"Institute for High Performance Computing and Networking (ICAR-CNR)"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2008,5,22]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.future.2006.05.009"},{"key":"e_1_2_1_2_1","volume-title":"Proceedings of the Second IEEE International Conference on Peer-to-Peer Computing (P2P'02)","author":"Andrzejak A."},{"key":"e_1_2_1_3_1","volume-title":"Proceedings of the 22nd International Conference on Distributed Computing Systems (ICDCS'02)","author":"Babaoglu O."},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.286.5439.509"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.5555\/554879"},{"key":"e_1_2_1_6_1","unstructured":"Camazine S.
