【摘要】 针对无线自组对等网中逻辑拓扑与物理拓扑之间的失配问题,综合节点位置信息和分布状况,构造出具有静态拓扑相关的无线自组对等网.通过中心节点获取网络拓扑的变化信息,将节点标号的最佳分配转化为最大旅行商问题.同时,采用模拟退火算法进行优化求解,实现了网络的动态拓扑感知性.仿真结果表明,该对等网在资源定位过程中,访问路径明显缩短,时延和数据丢包率明显减小.更多还原

【Abstract】 Aiming to solve the mismatch between overlay topology and physical topology,which exists in mobile Ad hoc network(MANET) peer-to-peer(P2P) networks,node location information and distribution condition are considered synthetically,and instantaneous topology-aware MANET P2P networks is got.A central node gets global topology changing information,and optimal identity(ID) allocation is translated into traveling salesman problem(TSP).Furthermore,optimal node ID order is obtained by using simulate annealing theory,and dynamic topology-aware MANET P2P networks is realized.Simulation results show that the path is shortened during resource locating,and the latency to service and droppacket rate are reduced as well.更多还原
