A commission was opened on Thursday before Mr. Barlow, one of the Commissioners in Lunacy, at the Gray's Inn Coffee-house, May 20th, 1858, to inquire whether the lie v. William James John Leach was of sound mind and competent to dispose of his property. The commission was issued upon the petition of Julia Caroline Leach, the mother of the supposed lunatic, and at whose death he will come into p...

Routing protocols play an important role in wireless sensor networks. There are primarily two types of protocols viz. data collection and data dissemination protocols. This paper compares two collection protocols: Base Station (BS) driven routing protocol [1] and a modified version of Low energy adaptive clustering hierarchy (LEACH) protocol [2]. The simulation results show that utilizing BS dr...

In wireless sensor network energy efficiency, Data security & Network reliability are a few of the most important aspects to be considered while tracking, monitoring and reporting the data. In the object tracking continuous reporting of data is required, which consumes more energy of network. In this paper, the focus is mainly driven over the survey of the energy-efficient object tracking clust...

Leach was the first most Routing Protocol used clustering concept in wireless sensor networks. Leach algorithmre-clustering process play vital role to gather data in cycles known as round. During each round a specific percentage of total nodes are elected as cluster heads (CHs). Each node get chance to become CH according to their probability in particular round. It is possible that not a singl...

In this paper we present an experimental analysis of the performance of the cluster formation phase of a wireless sensor network. Unlike previous works, this analysis considers the effect of channel errors overran adaptive transmission probability scheme that is used in the cluster formation phase. Particularly, we study the impact of channel errors over the energy consumption and the average c...

Wireless Sensor Network depends on nodes have limited energy, memory, computational power, range and it is important to increase energy efficiency by saving the battery power so as to extend the life time of the given WSN deployment. In WSN, data is measured by nodes and same is send to Base Station at regular interval. Different protocols are used for energy consumption, in wireless sensor net...

Wireless Sensor Network (WSN) consists of hundreds or thousands of sensor nodes which have limited energy, computation and memory resources. WSNs are highly affected by the energy dissipation of the nodes. LEACH is a cluster based routing for sensor networks for efficient data collection problem where small numbers of clusters are being formed in a selforganized manner. In this paper the advanc...

In Wireless sensor networks, sensor nodes sense the data from environment according to its functionality and forwards to its base station. This process is called Data collection. The Data collection process is done either directly or by multi-hop routing. In direct routing, every sensor node directly transfers its sensed data to base station which has an impact on energy consumption from sensor...
