In recent years, there has been a growing interest in wireless sensor networks. One of the major issues in wireless sensor network is developing an energy-efficient clustering protocol. Hierarchical clustering algorithms are very important in increasing the network's life time. Each clustering algorithm is composed of two phases, the setup phase and steady(More)
Energy efficiency is a critical parameter in wireless sensor networks. Clustering the nodes and controlling the number of cluster heads and members provides an effective way of energy efficiency. In this paper, we develop a clustering protocol for single hop wireless sensor networks. We utilize a competition algorithm for cluster selection phase that the(More)
Hierarchical clustering algorithms are very important in increasing the networkpsilas life time. In this paper, we developed the previous proposed algorithm EELTC (An Energy-Efficient Level-based and Time-based Clustering algorithm for Wireless Sensor Networks) that is called EELTC-M (modified EELTC). It is a new hierarchical clustering algorithm and has(More)
Wireless sensor networks consist of tiny sensors powered by low power battery and in most of the applications sensors are deployed to monitor the unattended areas. As sensor nodes are energy constrained in the network, energy efficiency is an important factor and should be considered during the protocol design phase. In this article we propose a robust,(More)
Clustering the nodes and controlling the number of cluster heads and members provides an effective way of energy efficiency. In this paper, we develop a clustering protocol for single hop wireless sensor networks. In the proposed algorithm some of the nodes become volunteers to be cluster heads. We develop a time based competitive clustering algorithm that(More)
