  • A review on the recent energy-efficient approaches for the Internet protocol stack 

    Authors:Cengiz, Korhan; Daǧ, Tamer
    Publisher and Date:(Springeropen, 2015)
    The reduction of energy consumption has become a key research area for the information and communication technology (ICT) industry due to economical environmental and marketing reasons. While the environmental direction aims at minimization of greenhouse gas emissions by enforcing the usage of renewable energy in the ICT industry economical and marketing directions lead researchers to design low-power components or develop and enhance energy-saving protocols without an impact on the level of the ...

  • Energy Aware Multi-Hop Routing Protocol for WSNs 

    Authors:Cengiz, Korhan; Daǧ, Tamer
    Publisher and Date:(IEEE, 2018)
    In this paper we propose an energy-efficient multi-hop routing protocol for wireless sensor networks (WSNs). The nature of sensor nodes with limited batteries and inefficient protocols are the key limiting factors of the sensor network lifetime. We aim to provide for a green routing protocol that can be implemented in a wireless sensor network. Our proposed protocol's most significant achievement is the reduction of the excessive overhead typically seen in most of the routing protocols by employing ...

  • Extending the lifetime of WSNs with Maximum Energy Selection Algorithm (MESA) 

    The limited battery supply of a sensor node is one of the most important factors that limit the lifetime of the WSNs. As a consequence increasing the lifetime of WSNs through energy efficient mechanisms has become a challenging research area. Previous studies have shown that instead of implementing direct transmission or multi-hop routing clustering can significantly improve the total energy dissipation and lifetime of a WSN. The traditional LEACH and LEACH based algorithms have evolved from this ...

  • Improving Energy-Efficiency of WSNs through LEFCA 

    Authors:Cengiz, Korhan; Daǧ, Tamer
    Publisher and Date:(Sage Publications Inc, 2016)
    Wireless sensor networks (WSNs) have become an important part of our lives as they can be used in vast application areas from disaster relief to health care. As a consequence the life span and the energy consumption of a WSN have become a challenging research area. According to the existing studies instead of using direct transmission or multihop routing clustering can significantly reduce the energy consumption of sensor nodes and can prolong the lifetime of a WSN. In this paper we propose a low ...

  • Multi-hop low energy fixed clustering algorithm (M-LEFCA) for WSNs 

    The limited battery supply of sensor nodes is one of the most important factors which restrict the lifetime of the wireless sensor networks (WSNs). As a consequence the wide deployment of WSNs in the recent years led to the necessity of extending the lifetime through energy efficient mechanisms. Previous studies have shown that instead of implementing direct transmission in a WSN field to collect data clustering can significantly improve the energy-efficiency and thus the lifetime. The traditional ...

  • Nearest Fixed Clustering Algorithm (NFCA) for Wireless Sensor Networks 

    The objective of reducing energy consumption at the sensor nodes has become a key research area for wireless sensor networks (WSNs) in recent years. With the steady increase in the cost of energy the existing algorithms and protocols need to be redeveloped. In this paper an energy-efficient routing protocol which forms fixed clusters is proposed. The new cluster head (CH) selections are made based on selecting nearest nodes to the current CH. The proposed protocol includes two phases to achieve ...

  • Towards energy-efficient MAC protocols 

    During the past two decades the ICT (Information and Communication Technology) has become an integral part of our lives with exponentially increasing user interest and the vast number of applications being developed and used. The downside of the increase in these numbers is the continuous increase in the energy consumption. Various resources indicate that nowadays ICT is responsible for around 2%to 5%of the total global energy consumption and as new technologies are being developed these numbers ...
