The need for efficient optimization of network resources to prolong the life time of large-scale and dense deployments of Wireless Sensor Networks opened the door for researchers to study and produce efficient clustering techniques. Clustering has been proven to be an effective approach for organizing a large scale WSN into connected groups increasing the life time and the reliability of such networks...
The denseness and random distribution of large-scale WSNs makes it quite difficult to replace or recharge nodes. Energy efficiency and management is a major design goal in these networks. In this paper, a new node energy efficient algorithm using energy thresholds to replace cluster heads is proposed. The proposed algorithm uses node ranking to elect cluster heads based on energy levels and positions...
The task of routing data from a source node to the base station is a critical issue in Wireless Sensor Networks (WSNs). Fuzzy logic is the main proposal of a number of papers in the literature as an effective method for making decisions to transfer data towards the destination. Although fuzzy logic has a very important role in designing routing protocols for WSNs, identifying its fuzzy sets and defining...
Wireless Sensor Network (WSN) performs energy extensive tasks and it is essential to rotate sensor nodes frequently so that Cluster Head selections can be made efficiently. In this paper, we aim to improve the lifetime of sensor network by using LEACH based protocols and efficiently utilizing the limited energy available in these sensor nodes. In sensor network, the amount of data delivered at the...
In a Wireless Sensor Network (WSN) the sensed data must be gathered and transmitted to a base station where it is further processed by end users. Since that kind of network consists of low-power nodes with limited battery power, power efficient methods must be applied for node communication and data gathering in order to achieve long network lifetimes. In such networks where in a round of communication...
Wireless sensor networks comprise of minor battery driven devices with restricted energy resources. Once installed, the minor sensor nodes are usually unapproachable to the operator, and thus auxiliary of the energy source is not practicable. Hence, energy proficiency is a vital design issue that needs to be boosted in order to increase the life span of the network. Numerous network layer protocols...
As the use of wireless sensor networks (WSNs) has grown enormously in the past few decades, the need of scalable & energy efficient routing and data aggregation protocol for large-scale deployments has also risen. LEACH is a hierarchical clustering protocol that provides an elegant solution for such protocols. One deficiency that affects the performance of the protocol is existence of very large...
The nodes in a sensor network are severely constrained by energy. Reducing the energy consumption of the nodes to prolong the network lifetime is considered a critical challenge while designing a new routing protocol. In this paper we propose a new power-aware, adaptive, hierarchical and chain based protocol - CCPAR (Clustered Chain based Power Aware Routing) that utilizes the periodic assignments...
Wireless Sensor Networks (WSNs) are highly distributed networks of small, light weighted, wireless nodes deployed in large numbers. These sensor nodes are immobile, non rechargeable with limited energy. The cluster-based protocols make judicious use of this limited energy. LEACH-C (Low Energy Adaptive Clustering Hierarchy-Centralized) has a drawback, a lot of energy is consumed by the nodes to send...
Nodes in WSN(Wireless Sensor Network) have limited energy. Once they are deployed, it is difficult to supply additional energy. Therefore the routing is most important for using energy efficiently in WSN. The routing protocols of this sensor network have two types: Directed Diffusion and SPIN such as Flat routing protocol, and LEACH (Low-Energy Adaptive Clustering Hierarchy) and LEACH-C (LEACH-Centralized)...
