This paper presents controlling of water distribution scheme, using the embedded system for performing crop specific irrigation activities using a PID controller that is designed to adjust remote sensors and actuator parameters. In addition, an automated approach is introduced to estimate the variance of the noise of the sensors during the operation. Considering detecting data acquisition context and automatic noise detection, the robustness of monitoring is enhanced against errors related to remote sensor context i.e., high temperature and variation capacity humidity. To achieve the best production of the crop, knowledge of the conditions of air and soil is required; use of smart irrigation reduces overall water consumption and improves Usage of water reserves. Smart usage of irrigation system optimizes land area productivity and conserves nature by control of climate including temperature, humidity and light intensity. There will be data acquisition from the sensors and then it will be compared with the threshold values and based on that decisions will be taken to water the crops by a microcontroller like PIC16F877A based interfacing unit, this microcontroller has been used in this paper to obtain low cost smart irrigation solution. This is a system useful for farms, greenhouses and the home gardening systems.
Keywords:- Soil Moisture Sensor, Pivot Irrigation, Pumping Motor, PID Controller.

This paper proposes and implements a solution for enhancing public transportation management services based on GPS and GSM. The microcontroller based in bus module consisting mainly of GPS receiver, GSM modem and, IR Sensor. GPS modem starts transmitting the current location of the bus and IR sensor counting the number of passengers on the bus then send this data to the GSM modem through the microcontroller. The microcontroller used as an interface between GPS receiver and GSM modem, after that the data is sent to a smartphone through short message service, the location of the bus can be viewed on Google Maps. Which it is designed an Android application for smartphones, the users of transportation service can locate their destination on Google Maps, then the application determines the location of the bus closest to them and the number of passengers. The results have shown that this developed system is useful for facilitating people using public transportation services.

Broadband speed has emerged as the single most commonly cited metric for characterizing the quality of broadband offerings. However, speed measurements for the same service can vary significantly. These differences arise from a complex set of factors including different test methodologies and test conditions. For any testing methodology, teasing apart the end-to-end tests and attributing performance bottlenecks to constituent parts is technically challenging. While the broadband access network can be the bottleneck, significant bottlenecks arise in home networks, end users’ computers, and server-side systems and networks. Consequently, inferences regarding how ISP delivered speeds compare with their advertised speeds need to be undertaken with careful attention to the testing methodologies employed. Many testing methodologies are inappropriate for the purposes of assessing the quality of a broadband network.

The objectives of this paper is to analyze voice and video over IP over LTE network from previous studies overview to be better than QoS to voice and video over IP over LTE network by using description and mathematics model only. After achieving the methodology use description and a previous study found that the LTE characteristics give high QoS in all parameters of QoS.

This paper is to plan and design OPNET simulation model to study and analyze delay in VoIP over WiMAX using IPv4 and IPv6. The model was designed and implemented using OPNET simulation. It was found that IPv4 has better performance than IPv6 concerning mean delay time and jitter, while IPv6 has better performance than IPv4 concerning end-to-end delay time.

Tremendous technological advances that have permeated all human sciences and all daily life, especially in the medical field, many assist technologies have been developed in the care of patients in hospitals. This technology has greatly helped to reduce the mortality resulting from the delayed provision of assistance to patients and critical cases; the nurse call system technology was one of the systems that marked a major shift in the organization of medical care in hospitals in general and in emergency and emergency care departments in particular. Which has had a significant impact on the reduction in mortality rates in hospitals and the rescue of critical cases and avoid the causes of delayed follow-up cases and prevent Vitality, which contributed to the ease of monitoring of the patient’s case in his request for help and immediate response to call as soon as possible, and helped in the process The administrative control for medical staff, especially nurses, by informing them clearly and urgently about the patient’s need for precise technological means. He also actively contributed to providing the best types of health care and minimizing concerns about the lack of interest by the medical staff working and Tranquility patients and their families, given the importance of mainstreaming such a system in hospitals and health centers, we find that the major interest in Sudan does not amount to the extent of its importance and the urgent necessity. This research examines the importance of this system and explains in practical terms how to create and design this system in hospitals. It also provides a comprehensive explanation of the components of the system, its design, its work and how to programming it. The results of this research show the practical application of this system, in Aliaa Specialized hospital, Khartoum state.

In fact, Quality of Services (QoS) is important for any WiMAX or broadband wireless communication, in order to ensure the satisfaction of users. Indeed this paper spots the light on estimating and analyzing two of QoS parameters, which are delay and jitter, where OPNET modular was utilized to create and analyze WiMAX network. In fact, the results show that the delay parameter was increased when mobile node number increased, while jitter levelled off.
