Clustering routing algorithm is an important and widely used method, which can prolong the lifecycle of WSN. Existing clustering algorithm due to the randomness of selecting the cluster head, it is inevitable that the agreement exists choosing cluster head unreasonable, node energy consumption unbalanced. To address the above issues, this paper presents an improved clustering routing algorithm LEACH-KED...
ZACA-EEC (Zigbee Ant Colony Algorithm Energy Efficient Cluster) routing protocol is proposed to replace AODV in Zigbee with the aim of increasing reliability for mine equipment monitoring in this paper, which can prolong the lifetime of network remarkably. Taking hydraulic support as an example, the distribution of monitoring nodes can be simplified as chain hierarchy topology, then Free-space model...
This paper considers a cluster-based wireless sensor network (WSN) where each sensor node takes turn to be cluster head. The main function of the cluster head is to oversee the communication within and between clusters while the remaining sensor nodes are involved in sensing of the surrounding environment. We address the sensor utilization problem where non-cluster head nodes in a cluster make decision...
Wireless sensor networks have become one of the most tempting networking technologies since it can be deployed without the need of a communication infrastructure. In general, there are some major concerns with this technology. That is, sensor node should have a long lasting system lifetime. And the system should keep the livability of nodes in a received level during the using process. In such systems...
LEACH is one classical protocol in wireless sensor network, which is a clustering-based protocol with good performance. In this paper, an improved routing algorithm based on LEACH protocol will be proposed, which involves cluster head choosing, multi-hop routing and the building of its path. Simulation in MATLAB, an improved routing algorithm has higher energy utilizing rate, and it helps prolong...
Clustering in wireless sensor networks is one of the crucial methods for increasing of network lifetime. There are many algorithms for clustering. One of the cluster based algorithm in wireless sensor networks is LEACH algorithm. In this paper we proposed a new clustering method for increasing of network lifetime. In proposed method Clustering is done symmetrically and the best node with respect to...
Cluster-based routing protocol is currently a hot research in wireless sensor network. In this paper, we propose an improved method RECHS(Redundant and Energy-efficient Clusterhead Selection) for LEACH protocol to balance network load and to extend the network life. In order to selecting reasonable clusterheads, our scheme first selects initial clusterheads and initial redundant clusterheads. By comparing...
The Wireless Sensor Network technology has been used widely; however the limited energy resource is one of the bottlenecks for its application. To enhance the robustness and accuracy of the information which is obtained by the entire network, certain redundancy exists in the data collected from the sensor node and thus data fusion processing is needed to reduce the redundant information. Firstly the...
A wireless sensor network consists of hundreds or thousands of small energy-limited sensors that are densely deployed in a large geographical region. It has been demonstrated that low-energy adaptive clustering hierarchy (LEACH) is an energy-efficient routing algorithm for wireless sensor networks (WSN). In this paper, we present a Time-based cluster-head selection algorithm for LEACH. We call this...
LEACH-DCHS CM (LEACH-DCHS cluster maintenance) algorithm based on LEACH-DCHS algorithm is proposed in this paper. By prolonging the steady-state phase time and retaining the concept of round in the original algorithm, the new algorithm achieves the purpose of saving energy ultimately. Simulation results validate the energy efficiency of LEACH-DCHS CM algorithm.
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
