无线传感器网络中,能量漏洞问题引起了很高关注.位于sink节点附近的网络节点因需要转发大量的数据包而过早地耗尽能量,导致网络生命过早的结束.提出一种新的分簇转发网络模型,基于该模型,提出相应的移动sink定位算法(CFSLA),算法根据各簇节点能量的分布情况,不断改变sink位置,有效地避免节点耗能不均,解决了能量漏洞问题.从实验和理论上,验证了该方法的有效性和可行性,比已有的算法有更好的效果.
In wireless sensor networks, the problem of energy loopholes has drawn much attention. Network nodes located near the sink node consume energy prematurely because of the large number of data packets to be forwarded, leading to the premature termination of the network life. Based on this model, a corresponding mobile sink location algorithm (CFSLA) is proposed. According to the energy distribution of each cluster node, the algorithm continuously changes the sink location and effectively avoids the energy consumption unevenness of nodes to solve the energy loophole problem. The experimental results and the experimental results show that the proposed method is effective and feasible, which is better than the existing ones.
