Modified LEACH – Energy Efficient Wireless Networks Communication
The final publication is available at www.springerlink.comMany algorithms and techniques were proposed to increase the efficiency of Sensor Networks. Due to high restrictions of this kind of networks, where the resources are limited, many factors may affect its work. Theses factors are: System throughput, system delay, and energy. Clustering protocols have been propose to decrease system throughput and system delay, and increase energy saving. In this paper, we propose a new technique that can be applied to sensor networks to produce high performance and stable Sensor Networks.http://link.springer.com/chapter/10.1007%2F978-90-481-3662-9_2
An improved modified LEACH-C algorithm for energy efficient routing in Wireless Sensor Networks
Wireless Sensor Networks (WSN) is mainly characterized by its limited power supply. Hence the need for Energy efficient infrastructure is becoming increasingly more important since it impact in network lifetime. Here the focus of this paper on Hierarchy clustering because multi-hope short range communication between wireless sensor nodes is energy efficient compared to Single-hope long range communication. In Hierarchy clustering, there are many Protocols but this paper talk about the well-known Low-Energy Adaptive Clustering Hierarchy (LEACH)[1].Centralized Low-Energy Adaptive Clustering Hierarchy (LEACH-C) and Advanced Low-Energy Adaptive Clustering Hierarchy(ALEACH) are energy efficient clustering routing protocol and they are belonging to hierarchy routing. In this paper we proposed Modified LEACH-C to upgrade the execution of existing Leach-C in such sort of Topology where Leach-C not performs so well. By Applying Method of Distance calculation between CH (cluster-head) to Member node and BS (base-station) to Member node. Making non-overlapping cluster using assigning proper ID while creating clusters. This makes the routing protocol more energy effective and delays life-time of a wireless sensor network. Simulation results demonstrate that Modified LEACH-C enhances network life-time contrasted with LEACH-C algorithm
Katakan tidak pada rasuah
Isu atau masalah rasuah menjadi topik utama sama ada di peringkat antarabangsa mahupun di peringkat dalam negara. Pertubuhan Bangsa- bangsa Bersatu menegaskan komitmen komuniti antarabangsa bertegas untuk mencegah dan mengawal rasuah melalui buku bertajuk United Nations Convention against Corruption. Hal yang sama berlaku di Malaysia. Melalui pernyataan visi oleh mantan Perdana Menteri Malaysia, Tun Dr. Mahathir bin Mohamed memberikan indikasi bahawa kerajaan Malaysia komited untuk mencapai aspirasi agar Malaysia dikenali kerana integriti dan bukannya rasuah. Justeru, tujuan penulisan bab ini adalah untuk membincangkan rasuah dari beberapa sudut termasuk perbincangan dari sudut agama Islam, faktor-faktor berlakunya gejala rasuah, dan usaha-usaha yang dijalankan di Malaysia untuk membanteras gejala rasuah. Perkara ini penting bagi mengenalpasti penjawat awam menanamkan keyakinan dalam melaksanakan tanggungjawab dengan menghindari diri daripada rasuah agar mereka sentiasa peka mengutamakan kepentingan awam
MODLEACH: A Variant of LEACH for WSNs
Wireless sensor networks are appearing as an emerging need for mankind.
Though, Such networks are still in research phase however, they have high
potential to be applied in almost every field of life. Lots of research is done
and a lot more is awaiting to be standardized. In this work, cluster based
routing in wireless sensor networks is studied precisely. Further, we modify
one of the most prominent wireless sensor network's routing protocol "LEACH" as
modified LEACH (MODLEACH) by introducing \emph{efficient cluster head
replacement scheme} and \emph{dual transmitting power levels}. Our modified
LEACH, in comparison with LEACH out performs it using metrics of cluster head
formation, through put and network life. Afterwards, hard and soft thresholds
are implemented on modified LEACH (MODLEACH) that boast the performance even
more. Finally a brief performance analysis of LEACH, Modified LEACH (MODLEACH),
MODLEACH with hard threshold (MODLEACHHT) and MODLEACH with soft threshold
(MODLEACHST) is undertaken considering metrics of throughput, network life and
cluster head replacements.Comment: IEEE 8th International Conference on Broadband and Wireless
