Multihop-Based Optimal Cluster Heads Numbers Considering Relay Node in Transmission Range of Sensor Nodes in Wireless Sensor Networks

Abstract

The data transmission of sensor nodes which detect events might be affected by their neighbor nodes located in their communication range. Thus, we analyze the energy consumption of sensor networks as a function of the number of cluster heads considering the above two options, multihop-based communication and the case where a neighbor node is in the transmission range for communicating data. This helps us to elect the number of energy-efficient cluster heads in a more practical manner. Also, we determine the effect of electing the number of cluster heads by restricting the local cluster size.

Service-Aware Clustering: An Energy-Efficient Model for the Internet-of-Things

“…The works most closely related to ours are found in [ 11 , 12 , 13 , 14 ]. The work in [ 14 ] considers a node’s service differentiation model similar to ours, but uses a flat topology, which is based on node weight differentiation during path selection.…”

“…This energy is the sum of the energy lost to switch capacitance ( ) and the energy lost in current leakage [ 13 ]. is the voltage supply, and is the latency for aggregating k bits of data from each m cluster members.…”

“…MOCRN [ 13 ] is another recent improvement of the LEACH protocol, which is based on the minimum separation distance between the cluster heads. Initially, MOCRN randomly selects K nodes as its cluster heads (CHs).…”

“…This differs from our model, which is based on hierarchical routing using service-aware clustering. While considering a centralized clustering scheme similar to ours, the works in [ 11 , 12 , 13 ] are not based on a service awareness/differentiation model similar to ours.…”

Modelling and QoS Implementation of Wireless Sensor Networks based on the Ant Colony Optimization Approach

“…Energy conservation and throughput maximization are two important performance parameters upon which the quality of service provided and large scale deployment of VSNs depends as they are expected to remain functional for many years before replacing the battery of a sensor node while providing a continuous stream of image data continuously. Several approaches have been proposed in the literature to minimize sensor nodes' energy consumption [4][5][6][7] but only few on VSNs throughput maximization.…”
