针对低功耗自适应集簇分层型( LEACH)协议中节点采集的数据存在大量冗余和能量消耗不均衡问题,提出一种能量高效路由协议MDG-LEACH。该协议基于虚拟网格和多尺寸网格选取活跃节点,采用综合考虑节点剩余能量和空间分布情况的簇头选择机制,簇头与基站之间根据动态规划方法建立最短传输路由树进行数据传输。仿真结果表明,与LEACH协议以及单剑锋的LEACH改进协议(计算机技术与发展,2013年第2期)相比,MDG-LEACH协议在均衡节点能量消耗和延长无线传感器网络寿命方面有了较大提高。
針對低功耗自適應集簇分層型( LEACH)協議中節點採集的數據存在大量冗餘和能量消耗不均衡問題,提齣一種能量高效路由協議MDG-LEACH。該協議基于虛擬網格和多呎吋網格選取活躍節點,採用綜閤攷慮節點剩餘能量和空間分佈情況的簇頭選擇機製,簇頭與基站之間根據動態規劃方法建立最短傳輸路由樹進行數據傳輸。倣真結果錶明,與LEACH協議以及單劍鋒的LEACH改進協議(計算機技術與髮展,2013年第2期)相比,MDG-LEACH協議在均衡節點能量消耗和延長無線傳感器網絡壽命方麵有瞭較大提高。

A new energy efficient routing protocol of MDG-LEACH is proposed in the paper,which is based on the question of numerous redundancies with data collecting in nodes and imbalance of energy consumption in Low Energy Adaptive Clustering Hierarchy ( LEACH ) protocol. It selects active nodes based on virtual grids and multiple dimensions grids. Further, it adopts cluster head choice mechanism in overall consideration of residual energy and spatial distribution of nodes and establishes the shortest transmission route tree between cluster heads and base station by the dynamic programming method for date transmission. Simulation results show that MDG-LEACH protocol improves LEACH protocol and the improved LEACH protocol ( Computer Technology and Development, 2013, No. 2 ) in balancing energy consumption of nodes and prolonging the life time of wireless sensor network effectively.
