| 摘 要： | 为了提高分布式数据关联中的通信效率,该文对其信息传播方法提出改进。首先,将对领域各节点分别传送消息改为广播一个领域各节点共享的信度,改进了信息形式和传播方法,大大减少了通讯量。其次,引入对数运算,解决了数值计算中的稳定性问题。模拟仿真结果表明,该算法节省了能量资源,增加了网络使用寿命,可方便地实现网络规模的可标度化,与理论分析一致。

| Abstract: | In order to increase the communication efficiency in distributed data association,this paper proposes an improved algorithm on its information propagation method.Based on the distributed calculation,this paper replaces transforming messages to every neighbour node by broadcasting a shared belief,and modifies the means of information expression and propagation,reducing communication volume greatly.The logarithmic operation is introduced during realization and the stability of numerical computing is solved.Th... |
