The selection of a chain leader is an important issue in wireless sensor networks (WSN). In this paper, we introduce a new method to select chain leaders in chain-based routing protocol using Neural Network (NN). Our proposed method can be applied to any chain based routing protocol such as PEGASIS (Power-Efficient Gathering in Sensor Information S...

In cloud computing systems, task scheduling is crucial. Task scheduling cannot be done based on a single criterion but rather on rules and regulations which can be referred to as an agreement between cloud customers and providers. This agreement is nothing more than the user's desire for the providers to offer the kind of service that they expect....

In wireless sensor networks (WSNs), reducing sensor node energy consumption and increasing network lifetime are becoming more and more challenging due to large scale in Internet of Things (IoT). Hierarchical protocols, especially Low Energy Adaptive Clustering Hierarchy (LEACH), are considered as the best energy-efficient for WSNs. However, LEACH n...

Tremendous evaluation of wireless mobile communication needs more efficient algorithms for communication systems. The use of conventional single-objective optimization algorithms may be unsuitable for real applications, because they act to the detriment of the rest of the performance parameters like lifetime network, delay, cost, and hop count; for...

The binding free energy represented by the residues of the interface are the hot spots and are the main factor in the stability of cells or chemical elements or their interactions and the development of their activities. Proteins, biological cells, and chemicals are distinguished by a structure that can be known about a cell or component, and each...

In recent years, researchers have focused on wireless sensor networks (WSNs). Because there are a lot of applications we used. The wireless sensor network consists of many small sensor nodes that contain a small and self-charged battery. Sometimes it is possible to change the power source of the node battery but sometimes it is impossible to do so,...

The main thing we work on is Wireless Sensor Networks (WSNs) which contain numerous sensor nodes with limited power resources, which report sensed data to the Base Station (BS) that requires high energy usage. We want to let the battery live as long as we can, as the cost of changing batteries of nodes is high and also difficult. So, we use effi...

Wireless sensor network (WSN) consists of small devices, which are called sensors. It is capable of sensing the environmental events, make processing of them and send data to the base station (BS), which needs high energy for its usage. This network which is limited to iterate the dead nodes, bring by energy depletion and to maximize the life-span...
