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

Energy Efficient Military Mobile Base Station Placement

This research deals with an energy efficient network for military mobile base station placement. The proposed method is based on minimizing the energy loss of military communication networks where the base station is moving along a preset path and the users are constantly moving in an independent speed and direction. It takes into account the free space loss and the knife edge effect for the energy loss to establish a path weight for the shortest path model. Then, it evaluates the neighboring points to the base station for the energy loss of the network in order to find the position at which the minimum energy loss occurs. The results show a clear energy saving advantage when compared to Lloyd-Max’s method

Armor-LEACH for Wireless Sensor Network

© ASEE 2008The use of sensor networks is increasing day by day; which offer more research topics to be discuss and modified; one of these topics is the power consumption that has to be reduced as possible, where the resources are limited; another topic is the security level that should be offer by such kind of networks. Clustered networks have been proposed in many papers to reduce the power consumption in sensor networks. LEACH is one of the most interested techniques that offer an efficient way to minimize the power consumption in sensor networks. TCCA provides LEACH with higher performance, by applying some modification to the way LEACH works. In this paper we combine two of the most powerful proposed techniques that can be applied on LEACH to reduce the power consumption and to increase the level of security

Clustered Hierarchy in Sensor Networks: Performance and Security

Many papers have been proposed in order to increase the wireless sensor networks performance; This kind of network has limited resources, where the energy in each sensor came from a small battery that sometime is hard to be replaced or recharged. Transmission energy is the most concern part where the higher energy consumption takes place. Clustered hierarchy has been proposed in many papers; in most cases, it provides the network with better performance than other protocols. In our paper, first we discuss some of techniques, relates to this protocol, that have been proposed for energy efficiency; some of them were proposed to provide the network with more security level. Our proposal then suggests some modifications to some of these techniques to provide the network with more energy saving that should lead to high performance; also we apply our technique on an existing one that proposed to increase the security level of cluster sensor networks.http://airccse.org/journal/nsa/0709s5.pd
