Wireless Sensors Networks (WSN) have become vital in many areas and critical applications. Some applications require a reliable network and less maintenance, especially the power consumption. ZigBee standard shows the ability to be used for many applications that require low data transmission and low power consumption. The standard helps the overall network to reduce worries about the sensors power...
Power consumption of routing protocols is one of the main issues that wireless sensor networks (WSNs) encounter in their lifetime. Low-Energy Adaptive Clustering Hierarchy (LEACH) clustering protocol was introduced to reduce power consumption. However, in LEACH, power consumption increases massively as the distance between sink node and cluster heads (CHs) increases. This drawback introduces distance...
Wireless Sensor Network is a rising technology that guarantees ample amount of applications in various domains. The creations of WSNs completely rely on existence of various hardware and software and WSN developed with limited battery life. Many WSN routing protocols are designed so that it makes use of fewer resources and improve the performance and lifetime of network. Energy consumption is one...
The deployment of Wireless Sensor Network(WSN) must be done with some kind of advanced techniques so that it can mitigate the energy constraints. An existing, clustered-based routing protocol known as Low-Energy Adaptive Clustering Hierarchy (LEACH) was studied, the outcome is an improved algorithm based on LEACH. The performance of these algorithms was studied through simulations using OMNeT++. In...
Wireless Sensor Networks (WSNs) typically aggregate sensed events into a sink by Continuous Monitoring (CM) or Event-Detection (ED). Cluster heads receiving and sending aggregated data have a difficulty in maintaining traditional cluster-based WSNs due to the energy hole problem, which leads to faster energy depletion around the sink. This paper shows how reporting frequency to the sink can be controlled...
Many research topics in recent years have focused on clustering algorithms as a scalable routing protocol in wireless sensor networks. In these algorithms, by the use of data aggregation techniques and reduction in sensors that should make long distance communications, energy consumption in total network lifetime is decreased. One of algorithms proposed in this field is DECSA. Aiming at the problem...
The sensors in sensor networks have limited energy and thus energy preserving techniques are important but in many cases like war zone the time for complete a task is more important than energy and in large-scale sensor networks, redundant communication between sensor nodes is necessary to propagate data in a large monitoring region. The main objective of this paper is to efficiently disseminate information...
High efficient routing is an important issue in the limited energy resource wireless sensor networks. Introducing Ant-colony algorithm, this paper proposes the wireless sensor network routing algorithm based on the LEACH. During the construction of sensor network clusters, only the nodes whose residual energy is higher than the average energy can be chosen as the cluster heads to avoid the node premature...
A cluster-based routing scheme for wireless sensor networks featuring adjustable cluster size is proposed in this article. Aimed at the reduction of power consumption, the proposed scheme is designed to adjust cluster sizes on the fly such that communication loads can be evenly shared by individual nodes, and consequently extend the lifetime of an entire sensor network. In the proposed scheme, named...
Power consumption is the main challenges of expanding the network, since the active nodes are more vulnerable to energy consumption. This paper proposes the tasks scheduling and distribution energy management mechanism of roles dormant cells (SRDC) to curb excessive consumption of energy consumed in the performance of duplicates task and unhelpful. Experimental results verify that the proposed of...
This paper talk about the communication protocol named LEACH. The protocol focuses on reducing the power consumption of wireless sensor networks, which can have significant impact on the overall energy dissipation of these networks. LEACH uses localized coordination to enable scalability and robustness for dynamic networks, and incorporate data fusion into the routing protocol to reduce the amount...
