Regional energy aware clustering with isolated nodes in Wireless Sensor Networks

Abstract

Energy consumption is an important issue in the design of Wireless Sensor Networks (WSNs) which typically are powered by limited energy. A suitable clustering algorithm for grouping sensor nodes can raise energy efficiency for WSNs. However, there exist some overheads for clustering, such as cluster-head selection, assignment, and cluster construction. In this paper, we propose a new regional energy aware clustering with isolated nodes for wireless sensor networks, called REAC-IN. In REAC-IN, the cluster-heads are selected by the calculated weight based on the residual energy of each sensor and the regional average energy of all sensors in each cluster. A distributed clustering algorithms may result in isolated nodes which are far away from cluster-heads. Such isolated nodes may need to communicate with the sink directly by consuming much energy. In order to reduce the energy consumption and prolong the network lifetime, we use regional average energy and the distance between sensors and the sink to determine whether the isolated nodes sleep or transmit data. Our simulation results validate that REAC-IN can outperform other clustering algorithms, such as LEACH, HEED and DEEC algorithms, and has better performance in terms of the total amount of transferred data, the total network energy consumption, and the network life-time.

A Byzantine Sensing Network Based on Majority-Consensus Data Aggregation Mechanism

“…Since then, many scholars [ 10 , 11 , 12 , 13 , 14 , 15 ] have proposed various methods entailing WSNs, such as SEP, PEGASIS, and HEED, to save energy and handle greater workloads; these methods extend the lives of sensor nodes and achieve the best operating efficiency in an environment with limited energy. In addition, some researchers [ 16 , 17 , 18 ] have surveyed and compared the aforementioned methods. The most well-known WSN algorithms are shown in Table 1 .…”

Estimation of Optimum Rendezvous Point for Mobile Sink (ORP-MS) in WSN

“…Energy conservation is a vital snag in WSN and is dually addressed by investigators all around the globe. Energy efficient clustering schemes having stationary base station are presented in [3], [7], [11], [19]. Mobile Sink schemes are elaborated in [16], [17], [20]- [29].…”

“…Information sensed by the sensors is sent to CH, which temporarily stores it. Finally the information gathered by nodes is communicated to BS,after fixed duration of time [3], [7]- [11]. In clustering the nodes which are unable to join the cluster are called as isolated nodes and are responsible for communicating information directly to the Base station (BS) [12].…”

Connected Dominating Set based Optimized Routing Protocol for Wireless Sensor Networks

“…In [8], the base station finds the highest energy node among the cluster and mark it as a cluster head for the current time to improve energy efficiency of the network. In [9], the authors propose regional energy aware clustering with isolated nodes for wireless sensor networks. The cluster-heads are selected by the calculated weights based on the residual energy of each sensor and the regional average energy of all sensors in each cluster.…”
