Wireless Sensors Networks (WSNs) have a big application in heterogeneous networks. In this paper, we propose and evaluate Advanced Low-Energy Adaptive Clustering Hierarchy (Ad-LEACH) which is static clustering based heterogeneous routing protocol. The complete network field is first divided into static clusters and then in each cluster separate Ad-LEACH protocol is applied. Our proposed protocol is inherited from LEACH with a cluster head selection criteria of Distributed Energy-Efficient Clustering (DEEC). This enables Ad-LEACH to cope with the heterogeneous nature of nodes. Due to small static clusters, each node reduces its broadcast message power because it only has to cover a small area. We perform simulations in MATLAB to check the efficiency of Ad-LEACH. The Simulation results show that Ad-LEACH outperforms LEACH and DEEC in energy efficiency as well as throughput.
无线传感器网络作为人类的一种新兴需求而出现。虽然这种网络仍处于研究阶段,但它们在生活的几乎每个领域都有很大的应用潜力。已经做了很多研究,还有更多的研究有待标准化。在这项工作中,基于簇的无线传感器网络路由进行了深入研究。在此基础上,通过引入\emph{efficient cluster head replacement scheme}和\emph{dual transmitting power levels},将无线传感器网络中最著名的路由协议之一LEACH修改为改进的LEACH(modified LEACH,MODLEACH)。我们的修改LEACH,在比较LEACH出执行它使用簇头形成,通过把和网络寿命的指标。然后,在改进的LEACH(MODLEACH)上实现了硬阈值和软阈值,使性能更加优越。最后,LEACH,修改LEACH(MODLEACH),MODLEACH与硬阈值(MODLEACHHT)和MODLEACH与软阈值(MODLEACHST)的吞吐量,网络寿命和簇头更换的指标进行了简要的性能分析。
Network lifetime and energy consumption of data transmission have been primary Quality of Service (QoS) obligations in Wireless Sensor Networks (WSNs). The environment of a WSN is often organized into clusters to mitigate the management complexity of such obligations. However, the distance between Sensor Nodes (SNs) and the number of clusters per round are vital factors that affect QoS performance of a WSN. A designer's conundrum resolves around the desire to sustain a balance between the limited residual energy of SNs and the demand for prolonged network lifetime. Any imbalance in controlling…
A Wireless Sensor Network (WSN) is made up of a large number of nodes that are spread randomly or on a regular basis to detect the surrounding environment and transfer data to a base station (BS) over the Internet to the user. It is widely used in a variety of civil and military concerns. Because the sensor has limited battery capacity, energy efficiency is a critical issue with WSNs. As a result, developing a routing protocol that decreases energy consumption in sensor nodes to extend the lifetime of the WSN using an intelligence algorithm has become difficult. LEACH is the first hierarchical…
WSNs are envisioned to consist of many small devices that can sense the environment and communicate the data as required. The most critical requirement for widespread sensor networks is power efficiency since battery replacement is not viable. Many protocols are proposed to minimize the power consumption by using complex algorithms. However, it is difficult to perform these complex methods since an individual sensor node in sensor networks does not have high computational capacity. On the other hand, many sensor nodes should transfer the data packet to the sink node that collects the required …
Wireless sensor networks (WSNs) has a practical ability to link a set of sensors to build a wireless network that can be accessed remotely; this technology has become increasingly popular in recent years. Wi-Fi-enabled sensor networks (WSNs) are used to gather information from the environment in which the network operates. Many obstacles prevent wireless sensor networks from being used in a wide range of fields. This includes maintaining network stability and extending network life. In a wireless network, sensors are the most essential component. Sensors are powered by a battery that has a fin…
Energy balancing through cluster head selection using K-Theorem in homogeneous wireless sensor networks
本文的目标是通过最小化远程通信和能量平衡来增加同构无线传感器网络(WSNs)的生命周期。传感器节点是资源受限的,特别是具有有限的能量,难以或不可能补充。LEACH(Low Energy Adaptive Clustering Hierarchy)是一种基于簇的无线传感器网络体系结构,其目标是在所有传感器节点之间均匀地消耗能量。在基于簇的体系结构中,簇头的作用对于无线传感器网络的成功运行是非常关键的,因为一旦簇头失效,整个簇就会失效。我们提出了一种改进的基于集群的无线传感器网络架构,通过引入一个协调器节点(CN),是丰富的资源。该CN负责在距离簇头较长的距离上向基站传输数据。我们提出了一种基于K-定理和其他参数,即剩余能量,距离协调节点,可靠性和程度的移动性的簇头选择算法。利用K-定理,根据簇内传感器节点的数目来选择簇头候选节点。我们相信,所提出的架构和算法,通过最小化通信和能量平衡,实现更高的能源效率。所提出的架构是更可扩展的,所提出的算法是鲁棒的均匀/不均匀的节点部署和节点移动性。
