The cluster-based routing protocols are most accepted to improve the network lifetime and to reduce the energy consumption of wireless sensor network. This paper presents the pollination based optimization algorithm also called OLEACH-C to improve the performance of LEACH-C protocol. The PBO algorithm is used for clustering in WSN. The node that has maximum remaining energy will be selected as ...

Energy efficiency is the most important issue in research of wireless sensor networks while the routing protocol plays an import role in achieving energy efficiency in WSN. In this paper, the deficiencies of LEACH are analyzed and an improved cluster-based energy efficient routing algorithm called ECHC is proposed. An election weight taking account of the residual energy and concentration of no...

Energy efficient routing is one of the key issues to prolong lifetime of wireless sensor networks (WSNs). The number of cluster and the distribution of cluster heads (CHs) have a major impact on the network performance. Energy-based clustering algorithm can greatly improve energy efficiency of WSNs because it adopts a multi-hop communication in each cluster. Besides, the neighborhood of the sin...

Wireless sensor networks provide the facility for collecting diverse types of data at frequent intervals, even multiple times per second and over large areas. Data-gathering wireless sensor networks (WSNs) are operated unattended over long time horizons to collect data in several applications such as those in climate monitoring and a variety of ecological studies. The proposed system considers ...

One of the most important issues in Wireless Sensor Networks (WSNs) is severe energy restrictions. As the performance of Sensor Networks is strongly dependence to the network lifetime, researchers seek a way to use node energy supply effectively and increasing network lifetime. As a consequence, it is crucial to use routing algorithms result in decrease energy consumption and better bandwidth u...

The optimum use of energy in wireless sensor networks (WSNs) is very important. The recent researches show that organising the network nodes in some clusters leads to higher efficiency of energy and finally it increases the lifetime of the network. So, controlling the number and the location of the clusters head (CHs) and also the size of the clusters about the node number leads to a balance in...

Wireless Sensor Network is built of more than a few nodes where each node is linked to one sensor. The main challenging task in this network is lifetime and energy consumption. The LEACH protocol is energy efficient protocol to reduce their energy consumption different modes is applied on the sensor nodes. These modes are sleep, Active and ready mode. These modes are applied on LEACH protocol a...

Wireless Sensor Network (WSN) consists of small low-cost, low-power multifunctional nodes interconnected to efficiently aggregate and transmit data to sink. Cluster-based approaches use some nodes as Cluster Heads (CHs) and organize WSNs efficiently for aggregation of data and energy saving. A CH conveys information gathered by cluster nodes and aggregates/compresses data before transmitting it...
