Hybrid multiple channel assignment algorithm based on node density

为了减小无线传感器网络中的同频干扰和避免网络堵塞问题,文章提出了一种基于节点密度的混合式多信道分配算法。该算法通过考虑链路干扰以及节点密度等因素,来解决局部严重同频干扰问题,实现各信道负载均衡,减少网络阻塞。仿真实验结果分析表明,该算法能有效地解决网络中同频干扰问题,较好地均衡各信道的网络负载,在数据业务较重的情况下,网络性能仍比较良好。

In order to reduce the co-channel interference(CCI)and avoid the network congestion in Wireless Sensor Networks(WSN), the paper proposes a hybrid multiple channel assignment algorithm based on node density. In this paper, the proposed algorithm can solve the serious problem of the local CCI by considering the factors such as link interference and node density,to balance the load of each channel, and reduce the network congestion. Our simulation results proof that the proposed algorithm can effectively solve the problem of CCI and balance the load of each channel. The performance of the network is still relatively good when the data traffic is heavy.
