例句与用法

Simulations show that using dual cluster head greatly decreases the message overhead for mute discovery and helps in extending the network lifetime
实验结果表明使用双簇首极大地减少了路由发现过程中的信息开销并且延长了网络的生命周期。
Network nodes are divided into clusters in geocrp , sensor nodes send data to their cluster heads and these data are transferred between cluster heads until they reach the sink node , such a hierarchical network structure can increase scalability of the network
Geocrp将网络中的节点划分成簇,感知节点采集的数据首先传送到其所在簇的簇头,再通过簇头之间的通信进行簇间中继,直到到达汇聚节点。
A new algorithm is proposed that promises to deliver solutions to both the problems mentioned above , by using dual cluster head , which is very useful to minimize the use of epidemic algorithms of any sort , thereby saving a lot of resources and also making mute discovery more easier
本文提出一种能解决以上两种问题的新算法，即在算法中使用双簇首，可以减少任何形式的流行算法的使用，因而节约了许多资源并且使得路由发现更容易。
In the paper , the protocol adopt special route optimize algorithm and tdma time slot assigning algorithm , make node enter low consumption or sleep state in order to reduce the consumption ; aiming at choice the mechanism of cluster head , multi - hop routing and the mechanism of mac , the existing leach protocol is improved
本文的网络协议是采用特殊的路由优化算法和tdma时隙分配算法,使节点进入低功耗或睡眠状态以降低功耗。协议主要在簇头的选择机制、多跳路由、 mac层通信机制等方面,对已有的leach协议进行了改进。
The innovations of this thesis can be summarized into three points . firstly , the average relative velocity is introducd into a novel adptive weighted clustering algorithm as one important parameter of weight , then it increases the stability and self - adaptability of cluster head . secondly , a new approach to calculating weight is suggested by integrating subjective and objective factors . it is verified by comparison with other approaches to selecting weight . thus the velocity of weight responding to the changes of network topology is increased . finally , using a som neural network to create a classifying model enables every node to learn to identify by itself the role in manet
本文的创新点有三个:首先本文在wca和aow分簇算法的基础上,引入了平均相对移动速度作为权值重要的参数,提出了一种新的基于权值的自适应分簇算法,提高了簇头在移动中的稳定性和自适应性;其次,提出了利用主客观综合赋权法确定权重的权值计算方法,通过与其他权重选择方法比较,网络结构变化的权值响应速度得到了改进;最后,论文利用自组织特征映射神经网络建立分类模型,使得网络中的节点可以自学习地确定簇中角色。
In the leach - new protocol , the mainly improvement of the leach protocol exhibits as follow : for the sake of balancing the network load , the network choose the clusters based on the residual energy ; we take multi - hop communication between sensors instead of single - hop communication , which results in the reduction of energy consumption of clusters ; the new protocol finds the path to the cluster head with the minimum cost , using an algorithm similar to flooding to propagate the cost information and greedy algorithm to find the lowest cost link ; the algorithm for assigning tdma time slot reduces overall delays of network
在leach - new协议中,对leach协议的改进主要体现在以下几个方面:根据节点剩余能量选择簇头,以平衡网络负载;节点间采用多跳路由,降低簇头能量消耗;节点根据能量消耗的代价来选择至簇头的路由,通过扩散算法来广播代价消息,采用贪婪算法来选择能量消耗最小的路径;采用tdma时隙分配算法减少网络时延。最后,利用ns2仿真软件进行验证。
