This paper presents the design and implementation of iPONICS: an intelligent, low-cost IoT-based control monitoring system for hydroponics greenhouses. The is based on three types sensor nodes. main (master) node responsible controlling pump, quality water in greenhouse aggregating transmitting data from slave Environment sensing nodes monitor ambient conditions transmit to node. Security activ...

In this paper, we propose a reliable high-speed UDP-based media transport with an adaptive FEC (forward error correction) error control. The proposed adaptive transport scheme controls the amount of redundancy by monitoring the network so that it can effectively adapt to the fluctuations of underlying networks. The monitored feedbacks of the receiver enable the sender to aware of current recept...

A Flow Control in Reliable Multicast transport protocol over combined (Fixed/Mobile) networks called (FCRM) is proposed. FCRM is based on a hierarchical structure where receivers are grouped into local regions. In each local region, there are special receivers, which are called Designated Receivers (DRs) and Mobile Agents (MAs). Each DR or MA is responsible for retransmission of requested packe...

Sensor-actuator networks are increasingly being used in distributed control of large scale systems. Often these applications are mission-critical and are required to maintain satisfactory performance in the presence of component failures. On the one hand, sensor-actuator network components are becoming inexpensive but they also tend to be unreliable, especially when deployed in harsh or unpredi...

sediment yield data, collected for most regions in iran has been insufficient and not so reliable and there is still not any sufficiently reliable methodology available for sediment yield assessment in the country as a whole. on the other hand, an attainment of reliable sediment yield data is a must and key requirement for the design of effective sediment management as well as control strategie...
