| 摘 要： | 结合遗传聚类算法及K均值算法，提出一种混合的节点聚类算法，在无结构P2P网络中根据节点之间的距离进行聚类，可以优化其覆盖网络，提高系统的路由效率。实验结果表明，该算法具有良好的可靠性及可扩展性，能对节点进行有效聚类，且聚类后的节点平均延迟明显降低。

| Abstract: | A two-tier service placement strategy based on the P2P overlay network framework is proposed. The optimization model is built for intra-domain Service Placement Problem(SPP) and an efficient algorithm is designed to solve the problem. Several cost calculation methods are adopted to fit different structures of the composed service. Simulation result shows the intra-domain service placement strategy decreases the cost for intra-domain composed services, and the two-tier service placement strategy decreases the total cost of composed services. |
