【摘要】 提出一种无结构环境下简单有效的节点间位置的比较方法,以DV(时延统计向量)作为节点在网络中位置的标识和比较peer间位置相近性的依据。给出基于此的节点邻居选择策略PSDV,保证节点的邻居在物理位置上与其是相近的。试验表明本策略能有效缩短节点与邻居间的时延,减少响应时间,证明本策略的合理性和高效性。更多还原

【Abstract】 Proposes a noble policy called PSDV, uses DV(delay statistics vector) as the basis to measure peers location proximity. Gives a neighbor selection policy based on DV to make sure that a peer’s neighbors are close to it in the physical location. The simulation experiment shows that the strategy can remarkably cut down the delay between peer and it’s neighbors, lower the response time, it proves that the validity and rationality of the ideas.更多还原
