A broadcast strategy based on K-ary N-cube topology in wireless sensor networks

研究了无线传感器网络的广播策略,提出一个冲突避免立方体广播算法CACB(Collision Avoidance Cube Broadcast)。CACB基于对k元n立方体结构的网络研究广播策略。CACB算法采用时钟准同步的方法,按照为序寻径的方式,确定每一个时间步应该如何去路由信息。实验使用OPNET软件进行仿真,仿真结果表明基于k元n立方体的无线传感器网络的广播算法CACB和传统的广播策略相比,能够减少最大端到端的时延,降低网络冲突,减少节点能量消耗,延长整个网络寿命,提高了网络的吞吐量。

The wireless sensor network broadcast strategy is mainly researched, it proposes a collision avoidance cube broadcast algorithm CACB. The CACB algorithm uses quasi-synchronous clock and the dimension order routing to determine each time step which should be to routing information and each time step select the determine nodes forward data. The experiment uses the OPNET simulation software, simulation results show broadcast strategy for wireless sensor networks based on k-ary n-cube compared to traditional broadcast strategy that can reduce the maximum end-to-end delay, reduce network conflicts, reduce node energy consumption, prolong the life of the entire network and improve the throughput.
