Wireless sensor networks are composed of numerous small charge, little power devices with sensing, local processing and wireless communication capabilities. Minimizing energy consumption and maximizing network lifespan are significant issues in the design of routing protocols for sensor networks. In this paper, we analyses the efficiency of LEACH protocol in extending the existence for energy-c...

Wireless sensor networks (WSNs) consist of various homogeneous or heterogeneous sensor nodes deployed over an area. The most challenging issue in wireless sensor network research is its routing protocols as the sensors have limited power so protocols should be like it consumes less energy during active mode. To increase lifetime of a sensor network is to design protocols in such a way that it m...

Wireless Sensor Networks are networks composed of large number of tiny, batter dependent sensor nodes comprising of restricted on-board storage, processing and radio potentials. Nodes sense the information from the surroundings around them and forward it to the central node which is labelled as Base Station. In view of the fact that the nodes consume lots of energy for this processing of data, ...

The most important factor within the wireless sensor network is to have effective network usage and increasing the lifetime of the individual nodes in order to operate the wireless network more efficiently. Many routing protocols have been developed for this purpose. One of these is the LEACH protocol presented by Wendi Heinzelman, which is especially well known as a simple and efficient cluste...

Wireless Sensor Network (WSN) comprises of sensor nodes, which form a network by building connections wirelessly, to send detected information from source to destination. Routing Protocols are utilized to shape honest to goodness and littlest routes between a starting node (source) and ending node (destination). Numerous WSN applications use various hierarchical routing protocols. Low Energy Ad...

In wireless sensor networks, sensor node always have a limited power resource. The energy consumed by sensor nodes to transfer the data to its destination becomes critical issue in designing WSN routing protocols. In this paper we propose a cluster routing protocol named I-LEACH to enhance the routing protocol LEACH. In the I-LEACH algorithm, selection of cluster heads is modified by using powe...

Water-environment monitoring network (WMN) is a wireless sensor network based real-time system, which collects, transmits, analyzes and processes water-environment parameters in large area. Both cluster selection mechanisms and energy saving strategies play an important role on designing network routing protocols for the WMN. Since those existing routing algorithms can not be used directly in t...

Due to the necessity of saving energy cost in low-powered devices, extending the lifetime of a sensor node powered by battery in both homogeneous and heterogeneous wireless sensor networks (WSNs) is area of interest. To save battery power in sensor networks, many research works including low energy adaptive clustering hierarchy (LEACH) and its variants use clustering techniques to reduce energy...

This paper gives a brief description about some routing protocols like EEE LEACH, LEACH and Direct Transmission protocol (DTx) in Wireless Sensor Network (WSN) and a comparison study of these protocols based on some performance matrices. Addition to this an attempt is done to calculate their transmission time and throughput. To calculate these, MATLAB environment is used. Finally, on the basis ...
