A WSN (Wireless Sensor Network) is made out of various number of hubs each of which comprise of detecting gadgets or sensing device to gather information from environment. These detecting gadgets are given processing unit to perform operations on information. These gadgets are conveyed arbitrarily in remote environment, because of which battery charging or substitution is not viewed as down to earth...

In this paper the entire area is divided into clusters. Each of the clusters has a set of nodes which are spread randomly across the clusters. Cluster Head Election algorithm LEACH elects a different cluster heading each round. LEACH routing algorithm is also simulated for sending the packets for inter cluster communication and intra cluster communication between source node and destination node....
The proposed work aims at designing routing method and data compression algorithm for WSN's. An ad-hoc network (WANET) is considered and based on certain criteria the data is forwarded dynamically. Various parameters such as Compression Ratio, Packet Delivery Rate, Energy consumption are considered to determine the efficiency of the network. One of the primary parameters to be considered in the configuration...
Wireless Sensor Networks (WSNs) are made up of tiny sensor nodes which sense the data and communicate to the base station via other nodes. These sensor nodes are inexpensive portable devices with limited processing power and energy resources which make them in need of smart clustering protocols. Many clustering and routing protocols were proposed in the literature to serve large networks of such tiny...
In this paper extension to LEACH protocol i.e. Modified LEACH protocol has been analytically and critically analyzed. It has been shown that the hard threshold value in Modified LEACH protocol has a direct impact on the network lifespan of a wireless sensor network. More the initial energy more will be the net lifetime of the network, as the number of alive nodes will be more. Simulation and analytical...
Wireless Sensor Networks (WSNs) comprise of large number of sensor nodes, which sense and measure various physical phenomena related parameters and transmit the measured data towards the base station by making use of the neighbouring nodes acting as relay nodes. In order to extend the lifetime of a WSN application, it is necessary to distribute the energy dissipated among the nodes evenly in the network...
Wireless sensor networks consists of hundreds or thousands of sensor nodes supported by small capacity battery. For environmental monitoring purposes, sensor nodes must have high endurance capabilities. Therefore, selecting suitable cluster heads (CH) location becomes a challenging issue. In this work, cluster heads distribution based on adaptive particle swarm (PSO) is proposed. PSO is one of the...
Extending the period of operation (lifetime) of wireless sensor networks (WSNs) is one of the most critical issues. Their limitations are due to limited energy resources. Available research results reveal that significant improvement in WSN lifetime can be achieved by adding spares (spare nodes). At the moment of WSN deployment, the minimum required coverage of WSN targets is assured by the primaries...
Cluster formation and cluster head selection are important problems in sensor network applications and can drastically affect the network's communication energy dissipation. However, selecting of the cluster head is not easy in different environments which may have different characteristics. In our previous work, in order to deal with this problem, we proposed a power reduction algorithm for sensor...
The use of Wireless Sensor Networks (WSN) is anticipated to bring lot of changes in data gathering, processing and dissemination for different environments and applications. Energy consumption is the most crucial design issue in WSN. In order to solve the issue and prolong the network lifetime, energy resources of each node in WSN need to be effectively managed. With respect to energy efficiency,...

Wireless sensor networks have serious energy constrain, since external power sources are typically unavailable. Typical wireless sensor nodes use batteries or fuel cells as the power source. The primary design goal of routing protocols is to efficiently use the energy of sensor nodes and prolong the survival time of the network. This paper analyzes the classical clustering routing protocol LEACH and...
Prolonging the lifetime of a sensor node powered by battery in both homogeneous and heterogeneous wireless sensor networks is a massive challenging area of research now-a-days. To achieve this target many research works including low energy adaptive clustering hierarchy (LEACH) and its variants use clustering techniques to reduce energy spent by keeping most of the nodes in sleeping mode whenever...
