LEACH 是一种经典的层次型路由协议,然而该算法簇头是自适应随机生成,未考虑当前节点剩余能量,因此簇头的选择会使网络中能量损耗不均衡,导致网络过早死亡。为了避免能量较少节点因为当选为簇头后过早死亡,提出了一种新的路由协议(LEACH-PHQ)。改进后的算法在簇头选择阶段综合考虑了各个节点的剩余能量,在数据传输阶段采用数据融合和多跳传输的策略。实验结果表明,改进后的方法有效地减少了网络能量消耗,保证了网络负载的平衡,又延长了网络的寿命。
LEACH 是一種經典的層次型路由協議,然而該算法簇頭是自適應隨機生成,未攷慮噹前節點剩餘能量,因此簇頭的選擇會使網絡中能量損耗不均衡,導緻網絡過早死亡。為瞭避免能量較少節點因為噹選為簇頭後過早死亡,提齣瞭一種新的路由協議(LEACH-PHQ)。改進後的算法在簇頭選擇階段綜閤攷慮瞭各箇節點的剩餘能量,在數據傳輸階段採用數據融閤和多跳傳輸的策略。實驗結果錶明,改進後的方法有效地減少瞭網絡能量消耗,保證瞭網絡負載的平衡,又延長瞭網絡的壽命。

LEACH is a classical hierarchical routing protocols. However, the algorithm is adaptive cluster head randomly generated. It does not consider the current node residual energy, so the choice of cluster head will make the network energy consumption which is not balanced, resulting in network premature death. In order to avoid less energy because elected as cluster head node after the premature death, we propose a new routing protocol(LEACH-PHQ). The improved algorithm in the cluster head selection phase took into account the residual energy of each node in the data transfer phase using data fusion transmission strategy. Experimental results show that the improved method is effective to reduce the energy consumption of the network and the network load balance, which can extend the network lifetime.
