| 摘 要： | 基于轨迹提出一种新的多路径构造算法,其基本思想是源节点根据目的节点位置信息选择几条合适的转发路径,中间节点根据不同的贪婪转发策略建立相应的动态转发表转发报文。和其他算法相比,新算法具有分布式特性,路径建立只需局部信息即可;算法实现简单,无须大量的计算。理论分析和模拟实验也表明,新算法具有较好的容错性。

| Abstract: | In order to improve the tolerance of routing algorithms, this paper proposed a new algorithm based on trajectory to construct multipath. Its basic idea is that the source node selects several suitable curves to sink at one time and intermediate nodes build dynamic forwarding tables according to different greedy forwarding strategies. Compared with other algorithms constructing multipath, this new algorithm only needs information in one hop and doesn't need too much calculation, so it is distributed and can be realized easily. Theoretic analysis and simulation results show that it is more tolerant. |
