摘要
在无线传感器网络中,由于节点的能量消耗不均衡,容易造成能量空洞,当能量空洞范围扩大到一定程度时会阻断路由,从而导致整个网络失效,造成能量的极大浪费;针对现有发送速率可调方法中的功率级别太多,计算较复杂,并结合跳数因子,提出了发送速率和跳数协同的自适应路由算法,其中对于功率的计算简单,并且在路由选择时基于剩余能量,充分利用能耗低的节点的能量,达到均衡整个网络能耗的目的;实验结果表明,此算法可以有效延缓能量空洞的形成速度,延长了网络寿命20%左右。
As the energy consumption of the nodes in wireless sensor networks （WSN） is not balanced and its limited energy of nodes, then forms energy hole easily. When the energy hole expanded to a certain extent, it will block the routing, resulting in failure of the entire network and a great waste of energy for the other nodes that still alive are remaining much energy but fail. Aiming at the shortcomings of the existing method of energy balancing strategy, proposed a self adaptive routing algorithm based on hops and adjustable transmission speed, it can make full use of the remaining energy. Experimental results show that this algorithm can effectively delay the forming speed of the en- ergy hole, thereby prolong the network lifetime.
