【摘要】：由于移動(dòng)P2P(Peer-to-Peer)網(wǎng)絡(luò)中節(jié)點(diǎn)自身狀態(tài)等因素的影響,節(jié)點(diǎn)往往表現(xiàn)出自私性和資源偏好性,這極大地影響了網(wǎng)絡(luò)系統(tǒng)的資源搜索效率。針對(duì)該問題,給出了一種移動(dòng)P2P網(wǎng)絡(luò)中基于節(jié)點(diǎn)協(xié)同合作度的資源搜索機(jī)制。該搜索機(jī)制通過綜合評(píng)價(jià)節(jié)點(diǎn)的信息轉(zhuǎn)發(fā)率、綜合相似度與核心度,選擇協(xié)同合作度高的節(jié)點(diǎn)作為中繼節(jié)點(diǎn)進(jìn)行信息轉(zhuǎn)發(fā);同時(shí),通過分析節(jié)點(diǎn)的主觀轉(zhuǎn)發(fā)率以建立其激勵(lì)機(jī)制,激勵(lì)節(jié)點(diǎn)參與資源搜索。分析與實(shí)驗(yàn)結(jié)果表明該搜索機(jī)制能夠有效地提高整個(gè)系統(tǒng)的資源搜索成功率,降低其平均搜索長度,具有較好的查詢性能。
[Abstract]:Due to the influence of some factors such as the state of the nodes in the P2P Peer-to-Peer network, the nodes often show selfishness and resource preference, which greatly affects the efficiency of resource search in the network system.In order to solve this problem, a resource search mechanism based on the degree of cooperation between nodes in mobile P2P networks is proposed.By synthetically evaluating the information forwarding rate, synthesizing the similarity and the core degree, the search mechanism selects the node with high cooperative cooperation degree as the relay node to forward the information; at the same time,By analyzing the subjective forwarding rate of nodes, the incentive mechanism is established to encourage nodes to participate in resource search.The results of analysis and experiments show that the search mechanism can effectively improve the success rate of resource search and reduce the average search length of the system, and it has better query performance.
