Wireless Sensor Networks (WSNs) consist of many sensor nodes, which are used for capturing the essential data from the environment and sending it to the Base Station (BS). Most of the research has been focused on energy challenges in WSN. There are many notable studies on minimization of energy consumption during the process of sensing the important data from the environment where nodes are dep...

Among traditional wireless sensor routing algorithm like LEACH, problems like unbalanced energy consumption in wireless sensor network, node losing efficacy because of large energy consumption, period uncertainty of periodic cluster head and unbalanced energy consumption between clusters come into being. Aiming at problem of unbalanced energy consumption between wireless sensor clusters, uneven...

A collection of huge number of a smaller amount of cost, a smaller amount of power as well as multifunctional small intelligent sensors is called as a Wireless Sensor Network(WSN). In these Wireless Sensor Networks, sensor nodes are have an extremely limited power supply. The main aim of this power routing procedure is dangerous for these Wireless Sensor Networks, because the majority of the se...

Wireless Sensor Networks (WSN) has become an interesting field of research because of its wide range of applications such as environmental monitoring, electromagnetic pollution monitoring, medical applications and industrial applications (Teo et al., 2007; Margi et al., 2009; Castelluccia et al., 2005; AbouElSeoud et al., 2010; Tavares et al., 2008). WSN consists of multi-functioning sensor nod...

It is the core issue of researching that how to prolong the lifetime of wireless sensor network. The purpose of this paper is to illustrate a clustering protocol LEACH-PF, which is a multihop routing algorithm with energy potential field of divided clusters. In LEACH-PF, the network is divided into a number of subnetworks and each subnetwork has a cluster head. These clusters construct an inter...

Wireless sensor network are sophisticated systems that are used to collect data from an inaccessible environment. They consist of base station and hundred to thousands of sensor nodes. Nodes in the sensor network are constrained by energy, processing power and memory. The sensor networks where base station is very distant from the sensor field, the energy efficiency in the working of sensor net...

One of the solutions to the lifetime problem of a wireless sensor network (WSN) is to select a sensor as the cluster head (CH) to reduce the transmission cost of the other sensors in a cluster. However, the high computation load will quickly run out of its energy. The most well-known method for selecting the CHs of a WSN is the so-called low energy adaptive clustering hierarchy (LEACH), but it ...

In today’s world Wireless Sensor Networks (WSNs) are an emerging technology for monitoring physical environment. WSNs consist of small nodes with sensing, computation and wireless communications capabilities. These sensor nodes are constrained in energy supply, processing and storage. Such constraints combined with a typical deployment of large number of sensor nodes have posed many challenges ...
