An Energy Efficient Data Gathering in Dense Mobile Wireless Sensor Networks

Abstract

Amidst of the growing impact of wireless sensor networks (WSNs) on real world applications, numerous schemes have been proposed for collecting data on multipath routing, tree, clustering, and cluster tree. Effectiveness of WSNs only depends on the data collection schemes. Existing methods cannot provide a guaranteed reliable network about mobility, traffic, and end-to-end connection, respectively. To mitigate such kind of problems, a simple and effective scheme is proposed, which is named as cluster independent data collection tree (CIDT). After the cluster head election and cluster formation, CIDT constructs a data collection tree (DCT) based on the cluster head location. In DCT, data collection node (DCN) does not participate in sensing, which is simply collecting the data packet from the cluster head and delivering it into sink. CIDT minimizes the energy exploitation, end-to-end delay and traffic of cluster head due to transfer of data with DCT. CIDT provides less complexity involved in creating a tree structure, which maintains the energy consumption of cluster head that helps to reduce the frequent cluster formation and maintain a cluster for considerable amount of time. The simulation results show that CIDT provides better QoS in terms of energy consumption, throughput, end-to-end delay, and network lifetime for mobility-based WSNs.

Efficient Clustering based Genetic Algorithm in Mobile Wireless Sensor Networks

“…The basic idea of Cluster Independent Data Collection Tree (CIDT) [13] is organizing a preferable Data Collection Tree (DCT). There are many factors that affect on choosing the data collection and CHs nodes such as nodes mobility, remaining energy, connection time, received signal intensity, and finally, cluster dimension.…”

“…There are various types of mobility in MWSNs such as mobile sink only [5], mobile sensor nodes only [6][7][8][9][10][11][12][13][14][15][16][17][18], or joint sink and sensor nodes mobility [19]. The limited power, radio capability, and storage area due to the small size of the nodes leads to developing many clustering routing protocols in static WSNs to utilize this limited energy and resources.…”

“…A Cluster Independent Data collection Tree (CIDT) was designed in [36] based on construction of Data Collection Tree (DCT) to provide a guaranteed reliable network about mobility, traffic, and end-to-end delay. The CIDT consists of a setup phase and a steady-state phase.…”

Mobile Wireless Sensor Networks: An Overview

“…VELCT [40] is a hybrid topology (i.e., cluster and tree topology) based energy efficient routing scheme, which has been particularly designed to improve the network performance, data collection and lifetime of large scale mobile WSNs. VELCT is an enhancement of CIDT technique, which effectively mitigates the existing issues in network topologies such as residual energy consumption, coverage problem, critical node occurrence, RSS, traffic, connection time, tree intensity, scalability, fault tolerance, delay, throughput, PDR, mobility and network lifetime.…”
