[Industry researchESCAL_An_Energy_Saving_Clustering_Algorithm_Based

Description: Abstract—the application of wireless sensor network (WSN) is always restricted by the energy shortage of sensor nodes. In order to reduce the entire energy consumption of the WSN, a promising approach is to design light clustering algorithms.LEACH is such a well-known clustering algorithm that was designed to distribute the energy consumption to nodes in the WSN evenly. LEACH is characterized by its attactive clusterbased strategy however, in the algorithm, energy dissipation of entire network is still great during the process that cluster-heads (CH) transmit data to base station (BS). In this paper, based on LEACH, we propose a modified clustering orithm which is named ESCAL. In ESCAL, CHs won’t communicate with BS directly, but transfer aggregated data to the nearest node in term of received signal strength then this elected nearest node willcompress and forward the data to BS.-Abstract—the application of wireless sensor network (WSN) is always restricted by the energy shortage of sensor nodes.

[3G develops02-5

Description: Power consumption is an important design criterion in the design of wireless sensor networks. Hybrid radio frequency/free space optical wireless sensor networks (RF/FSO WSN) have been proposed to reduce the energy consumption of traditional RF-based sensor networks. This paper compares the performance of such a hybrid sensor network against the wellknown RF-based low energy adapting clustering hierarchy (LEACH) WSN proposed in the literature. Network performance is studied in terms of network lifetime and average network area coverage. Simulations show that despite not employing data aggregation, the RF/FSO WSN has a longer lifetime and larger average network coverage when compared to the LEACH WSN

Description: 关于现有的基于WLAN,蓝牙以及RFID等的定位算法的综述和系统比较。是content-aware下的新兴的应用领域,有很大发展空间-Location, Localization, and Localizability Location-aware technology spawns numerous unforeseen pervasive applications in a wide range of living, pro- duction, commence, and public services. This article provides an overview of the location, localization, and localizability issues of wireless ad-hoc and sensor networks. Making data geographically meaningful, location information is essential for many applications, and it deeply aids a number of network functions, such as network routing, topology control, coverage, boundary detection, clustering, etc. We investigate a large body of existing localization approaches with focuses on error control and network localizability, the two rising aspects that attract signi¯ cant research interests in recent years. Error control aims to alleviate the negative impact of noisy ranging measurement and the error accumulation e® ect during coope- rative localization process. Network localizability provides theoretical analysis on the per

Description: LEACH (Low Energy Adaptive Clustering Hierarchy) is designed for sensor networks where an end-user wants to remotely monitor the environment. In such a situation, the data from the individual nodes must be sent to a central base station, often located far from the sensor network, through which the end-user can access the data.

[File FormatLEACH

Description: LEACH [1] is an autonomous adaptive clustering protocol that distributes the energy load evenly among the sensors in the network using randomization. The nodes organize themselves into local clusters, with one node acting as the local base station or cluster head. In order to not drain the battery of a single sensor randomized rotation of the high-energy cluster head position such that it rotates among the various sensors. Once the cluster head has all the data from the nodes in its cluster, the cluster head node aggregates the data and then transmits the compressed data to the base station. Since it compress the amount of data being sent from the clusters to the base station, energy dissipation is reduced and system lifetime is thus enhanced.

Description: Wireless Sensor Network is the network of power-limited sensing devices called sensors. Wireless sensor network is differ other networks in terms of optimization of amount of energy because when these sensors sense and transmit data to other sensors present in the network, considerable amount of energy is dissipated. Various routing algorithms are proposed to limit the powers used by the wireless sensors. Hierarchical routing protocols with the concept of clustering like LEACH and and DEEC are already best known for maintaining energy efficiency. In this submission, we will compare these two protocols.-Wireless Sensor Network is the network of power-limited sensing devices called sensors.
