We perform packet forwarding simulations where packet forwarding probabilities (PFP) are used as the model for representing packet routing strategies. The PFPs of every node are determined based on congestion avoidance factors and the PFP mixtures of shortest path routings and random walks. Our simulations shows that there are the most effective mixture rates to reduce the congestion of communication networks, in particular, a scale-free network with a large exponent of a power law due to hub nodes with large degrees.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"168","bibliographic_titles":[{"bibliographic_title":"研究報告数理モデル化と問題解決（MPS）"}],"bibliographicPageStart":"165","bibliographicIssueDates":{"bibliographicIssueDate":"2009-02-26","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"19(2009-MPS-73)","bibliographicVolumeNumber":"2009"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":61936,"links":{}}
