Wireless Sensor network (WSN) has added a new dimension in the field of wireless communication. As the sensor nodes are placed at remote places and are equipped with limited sources of battery power, proper energy efficient routing algorithms as well as clustering protocols are highly needed to make the system more energy efficient. Such an energy efficient clustering algorithm has been presented...
Wireless Sensor Networks have been organized for various aspects like, data collection, security, tracking, military applications etc. But one of the major challenges in Wireless Sensor Network (WSN) that is yet to be sorted out is the lack of energy efficiency which retards the lifetime of the network. Clustering or Hierarchical routing is good solution for reducing much of energy consumption in...
Wireless Sensor Network (WSN) is most integral part of our day to day life. They are widely used in various applications. Many Clustering based algorithms have been proposed for designing WSN. Some of them are fuzzy based approaches. The purpose of this paper is to propose a clustering based approach with fuzzy logic and relay node implementation that can cope up with drawbacks of the previously proposed...
Wireless Sensor Networks consist of nodes which are deployed over the field to gather useful information and send the required data to the base station for further processing. In WSNs, nodes have limited power and shorter lifetime so, it is critical to collect the information in an energy efficient manner and enhance the lifetime of the network. Ant Colony Optimization, a Swarm Intelligence based...
In Wireless Sensor Network (WSN), the life span depends on the energy consumption of the sensor nodes. By reducing the energy consumption of each node frequent node failure can be minimized which in turn increase the lifetime of the network. Among various techniques, clustering is a key technique for extension of network lifetime by reducing the energy consumption. In this paper, we focused on simulation...
Data transmission is the most important issue in wireless sensor network (WSN). The energy consumption and latency are the key factors of data transmission. To optimize these factors, a noble data aggregation algorithm is proposed in this paper. The proposed algorithm is originated from LEACH, and energy efficiency and latency is considered as the researching parameters. The overlap of detect regions...
On the basis of analyzing the Low-Energy Adaptive Clustering Hierarchy (LEACH), a clustering routing algorithm for Wireless Sensor Network (WSN) based on ant colony algorithm (ACA) is proposed in this paper. We applied the ACA to inter-cluster routing mechanism and looked for the best path from cluster heads to base station. Thanks to the algorithm, the transmission of information, for the cluster...
