“…where E SN is the energy dissipated to send one packet to CH and E Tx_DCR is the amount of energy dissipated to send one packet to the sink. Here, E SN is calculated by (6) and E Tx_DCR is calculated according to [15,20]. If we consider that average distance to the sink…”

“…So

The vice node energy consumption can be calculated as

E_{vice} = l E_{SN} + ()(, \frac{N}{K_{normalc}} - 1) l E_{elec} + ()(, \frac{N}{K_{normalc}} - 1) l E_{Tx_DCR},

E_{Tx_DCR}

is the amount of energy dissipated to send one packet to the sink. Here,

“…So, the CHs consume a large amount of energy and they vanish very quickly, sometimes even before sending the collected data to the sink. The main idea of the DCR‐LEACH protocol is to help the CHs, which suffer from low residual energy, to cooperate with the most energetic nodes, selected as vice nodes, to communicate the collected data to the sink [14, 15]. The lifetime of the network is divided into rounds.…”

Reducing energy consumption is a key challenge in the design of any routing protocol dedicated to wireless sensor networks (WSNs). In this study, the authors introduce a new low energy consumption protocol based on a cooperative relaying technique. The proposed protocol is called distributed cooperative relaying low energy adaptive clustering hierarchy (DCR-LEACH) protocol, and is a way of improving the LEACH protocol. The authors have exploited cooperative relaying transmission techniques, in order to enhance LEACH for large-scale WSNs, whereby, a cluster head cooperates with the most energetic nodes in order to transmit collected data to the sink. To evaluate the energy efficiency of the proposed DCR-LEACH, they derive the expressions of energy consumption by applying a cooperative relaying technique and simulate the DCR-LEACH using NS-2 for three different scenarios. To confirm the efficiency of the DCR-LEACH protocol, they compare the proposed scheme with both LEACH and multi-hop routing LEACH (MR-LEACH) protocols. The experimental results prove that for large-scale WSNs, the performance of DCR-LEACH protocol is better than MR-LEACH and conventional LEACH in terms of network lifetime, energy consumption, and number of data transmission.
