One of the major concern of Wireless Sensor Networks (WSNs) is to minimize the energy consumption of the sensor nodes. In multi-hop clustering, sensor nodes closer to the Base Station (BS) deplete their energy faster as compared to far away nodes. Transmission of own data as well as other nodes data by the nearer nodes is the prime cause for this uneven energy consumption. Hence, the nodes closer...
One of the most well-known clustering methods for wireless sensor network is, no doubt, the so-called low energy adaptive clustering hierarchy (LEACH) because it is simple and easy to implement. Although LEACH tries to provide a fair selection mechanism by randomly selecting a number of sensors as the cluster-heads, it does not take into account the distribution of sensors, the main reason that LEACH...
A nodes scheduling method applying for high density and large-scale WSN is put forward by using probabilistic coverage sensing model in this paper-that is the Distributed Probabilistic Coverage Sets Configuration Method (DPCS). In this method, the nodes with dense distribution are divided into several non-overlapping coverage sets by adopting distributed self-organization method. In the process of...

A Wireless Sensor Network consists of enormous amount of sensor nodes. These sensor nodes sense the information from the sensing region and transmit to the sink. From the sink a client can access the required information. Essential part of the wireless sensor network is the sensor nodes that are driven with the batteries. Prolonging the network lifetime is very difficult and expensive in many conditions...
With the advent of Internet and computational era, not only opportunity to send and receive data between humans, but also among the devices without human control over it. This is known as Internet of Things (IoTs) concept which can be applied for solving the growing issue of power/energy management. A solution is a cheap and easy to implement and manage energy monitoring system for our daily usage...
The coming generations are using the wireless sensors, and all of these networks have been deployed across various areas. Also they are used with the real time systems thus catering to the needs of the present scenario which the traditional methods have failed. These wireless networks deploy sensors around the area, but the disadvantage lies that these sensors have very limited battery life, so to...
Wireless Sensor Networks (WSN) consists of independent sensors distributed across different locations, which are used to continuously record the environmental or physical conditions. The recorded data will be passed through the network from a sensor to a main location. Sensors life time is based on the battery power. Lower the battery power leads to decrease in lifetime for a sensor. It is important...
Wireless sensors are used to acquire the data from different environments such civilian applications, military, tracking, seismic measurements and monitoring applications in order to take necessary actions or to prevent the disasters, to do so all sensors consumes more energy. Since, the sensor is a battery operated device the lifetime of each sensor is reduced. Therefore effective cluster formation...
Wireless sensing element Network may be a network distributed in universe. This one consists of big quantity of nodes that are helpful in assembly of information within the various setting. However the nodes operate on battery of adequate power. As the nodes died, the network time period is reduced. Thus raising the network time period is final issue of sensing element network. This paper proposes...
Wireless sensor network (WSN) comprises of several nodes usually called motes or sensors. These motes gathered together and collect data by observing the surroundings and reported the information to one or more reliable links. This valuable data only be accessible between two communicating parties. To secure the data that delivers between the two parties, we require a secure node authentication scheme...
Internet of Things (IoT) is a new paradigm which is enormously gaining ground in today's world. In order to maintain desirable service quality in the transmission of sensed data, data aggregation schemes are highly used.

Energy efficient data collection is the major challenging task in the Wireless Sensor Network(WSN). Since, batteries are the main power sources of sensor nodes which has limited energy. In multi hop clustering, Base Station's neibourhood nodes have overload compare to far nodes because nearer nodes transmit their own data as well as other nodes data. As a result, the Base Station (BS) nearby nodes...
