Smart city has developed energy, environmental, and healthcare services.  It is also continuously providing new services to all citizens.  This paper is concerned with the design and implementation of smart meter system as the core for smart grid in smart city.  A system is proposed where the electricity supply is monitored by measuring its related parameters (voltage, current, power, energy consumption, and consumption bill) and issuing Short Message Service (SMS) notification of the consumption.   The designed system used PZEM-004T, Arduino Mega, Raspberry Pi and Node-Red platforms.  The data related to the measured parameters are successfully transmitted to the datacenter using Message Queuing Telemetry Transport (MQTT) protocol, stored in MySQL database using core python program, and displayed on Node-Red platform.  The test and verification of the system are performed using different scenarios showing that successful and accurate operation of the system components are achieved.   Finally, the designed system can be extended to cover large geographical areas and can be modified to serve for pre-paid arrangement in an effort to assist in reducing the electricity consumption in Iraq with the continuing crises of electricity.

Autonomous robotic monitoring of human and animal used to secure the house or the flat. This robot can move freely from one side to another side of the house or the flat. Accordingly, this robot is sending the vision to android smartphone in real time. Therefore, the owner of the house or the flat can see inside the house while they were not around. The objective of this research is to develop autonomous robotic to be able to monitor the area from the existing of human and animal and send the vision to android smartphone in real time. This research used four leg robotic as an autonomous robotic monitoring. Four leg robotic is equipped with camera which connected to router based on wireless connection, PIR and ultrasonic sensor and GSM module to send short message service (SMS) notification if PIR sensor detect some movement. The experiment used cat as an animal object. Experiment showed that this robot can follow the object, either a human or an animal, within range of 10–45 cm from robot in 12 seconds and send the vision to android smartphone in real-time. The SMS is received in 5 seconds after camera capture the object. This robotic cannot determine who is the object on the camera because it is not equipped with object detection system.

This paper describes issues and challenges in the design and implementation of interactive client-server applications where program logic is expressed in terms of an extensible markup language (XML) document. Although the technique was originally developed for creating interactive short message service (SMS) applications, it has expanded and is used for developing interactive web applications. XML-Interactive (or XML-I) defines the program states and corresponding actions. Because many interactive applications require sustained communication between the client and the underlying information service, XML-I has support for session management. This allows state information to be managed in a dynamic way. The paper describes several applications that are implemented using XML-I and discusses design issues. The software framework has been implemented in a Java environment.
