摘　　要：在无线自组对等网的构建中,采用跨层设计机制,对传统Chord组网协议进行改进。将接收信号的能量用于估计节点之间的距离,用节点的指针表信息对网内节点分布的疏密进行估计,获得一个兼顾逻辑网与物理网之间匹配和系统负载平衡的节点标号,提出一种新型无线自组对等网构建方法。仿真结果表明,在基于该方法的无线自组对等网中,资源定位路径缩短,时延和丢包率减小,网络的负载能力得到了提高。In the construction of Mobile Ad hoc Peer-to-Peer Networks（MANET P2P）,cross-layer design idea is utilized,and through modifying the traditional protocol named Chord,a novel construction method for P2P MANET is presented,in which the received signal power and node finger table are used to estimate the distance between two nodes and local node distribution density respectively.A node ID is allocated to realize matching between logical network and physical network,as well as load balance.Simulation results show that the MANET P2P constructed through the proposed method shortens the resource-locating path,minimizes the latency and drop-package rate,and load capability is improved.
