In wireless sensor networks, failures occur due to energy depletion, environmental hazards, hardware failure, communication link errors, etc. These failures could prevent them to accomplish their tasks. Moreover, most routing protocols are designed for ideal environment such as LEACH. Hence, if nodes fail the performance of these protocols degrade. In this context, we propose two improved versi...

In this paper an Energy Efficient Clustering Scheme with Mobile Sink (EECSMS) for Heterogeneous Multilevel Wireless Sensor Networks is proposed. In EECSMS, the cluster-heads (CHs) are elected by a probability based on the ratio between residual energy of each node and the average energy of the network, the sink or base station (BS) moves towards each CH by a distance proportional to that CH’s p...

In Wireless Body Area Networks (WBANs), the extremely sensitive data transmission mainly requires fault tolerance and consistent data transmission. In this study, we propose a Cluster Based Failure Detection and Recovery Technique for WBAN which presents a hierarchical architecture. Here, local nodes are connected to their Cluster Heads (CHs). Each CH is interconnected and also connected with a...

A new energy aware routing protocol to optimize energy consumption and prolong network lifetime for Wireless Sensor Networks (WSNs) had been proposed in this paper. Cluster based routing techniques like the conventional Low Energy Adaptive Clustering Hierarchy (LEACH) are used to achieve scalable solutions and extend the network lifetime until the last node dies. Improved Energy Efficient LEACH...

This paper examines the optimization of the lifetime and energy consumption of Wireless Sensor Networks (WSNs). These two competing objectives have a deep influence over the service qualification of networks and according to recent studies, cluster formation is an appropriate solution for their achievement. To transmit aggregated data to the Base Station (BS), logical nodes called Cluster Heads...

Clustering has long been regarded as an efficient technique for data collection in wireless sensor networks. The approach divides network into clusters and makes cluster heads (CHs) responsible for data aggregation. However, due to the constraints on available resources, a sensor node is likely to be selfish and refuse to declare itself as a cluster head. In this paper, we propose a game-theory...

Received Nov 29, 2017 Revised Jan 27, 2018 Accepted Feb 19, 2018 Clustering is used for prolonging the network lifetime in WSN. It groups sensor nodes into different groups and selects a single node as a cluster head (CH) for all the groups. CHS collect the data from consonant clusters and forward the data to base station. In this paper, we proposed path optimization algorithm in Wireless Senso...

Internet of Things (IoTs) as a new network pattern for the intelligent world usually uses wireless sensor networks (WSNs) perception layer which consisted numerous number nodes scattered in environment to gather intended information. The selected information then is sent base station (BS) be cloud server further processing. Since energy limited, most significant challenge these reducing consump...

Data Aggregation techniques are used in wireless sensor networks (WSNs) to collect the data samples from sensor nodes (SNs). Data aggregation techniques for WSNs must address to the issues of WSNs like limited energy, fast and efficient query response, which are essential for network’s performance and maintenance. In this paper, we propose an energy-efficient cluster based task scheduling algor...
