According to the fundamental goal of remote sensing technology, the image classification of desired sensors can be introduced as the most important part of satellite image interpretation. There exist various algorithms in relation to the supervised land use classification that the most pertinent one should be determined. Therefore, this study has been conducted to determine the best and most su...

In this paper we present a model for the lifetime of wireless sensor networks. The model takes into consideration several parameters such as the total number of sensors, network size, percentage of sink nodes, location of sensors, the mobility of sensors, and power consumption. A definition of the life time of the network based on three different criteria is introduced; percentage of available ...

In Wireless Sensor network (WSN) the energy consumed by the sensor network determines the wireless sensor network lifetime. By minimizing the power consumption of each node, the overall energy of the sensor network can be efficiently improved which in turn also improves the network lifetime. This can be achieved by using Multi hop communication. Though the energy consumed is reduced, the delay ...

1.0 INTRODUCTION Advancement in technologies such as sensing, electronics and computing have attracted tremendous research interest in the field of wireless sensors network (WSNs). Apart from their enormous potential for both the commercial and military applications wireless sensors network is generally consist of large number of low cost, low power multifunctional energy constrained sensors no...

This work aims to propose and design a class of networks coupled linear nonlinear oscillators, in which short bursts exogenous excitation result sustained endogenous network activity that returns quiescent state only after characteristic time along different path than when originally excited. The desired hysteretic behavior is obtained through the coupling self-excited oscillations with purpose...

Sensors are used to monitor and control the physical environment. In mobile sensor networks, nodes can self-propel via springs, wheels, or they can be attached to transporters, such as vehicles. Sensors have limited energy supply and the sensor network is expected to be functional for a long time, so optimizing the energy consumption to prolong the network lifetime becomes an important issue. I...

Self organization is one of the most important characteristics in an Ad-hoc Sensor Network. Thousands of Sensors are deployed in a geographical area randomly without considering the location factor. After deployment, sensors are to self organize themselves to form a network of their own. How well the network is formed determines the life of the whole network as well as the quality of data trans...
