Abstract: Private and public transportations are use as common mobility of people, making it important to know where traffic congestions, car accidents and other related vehicular activities that may ruin your way to office works or to your destinations be avoided. Philippines is known to be one of the most traffic congested in the world due to uncontrollable volumes of cars running in major streets every day. In this paper, a proposed wireless device that can be attached to a vehicle was developed to track the route using global positioning system, perform geo fencing and perform controlling mechanism to help the driver locates a shortest path, avoid traffic jams, and do messaging and traffic advisories based on contacts and information stored in the software utilities. Based on initial testing, the software is capable of recording and reading vehicle logs, activating GPS route, reading accelerometer log, and reading compass log as bases of controlling mechanism while the device is activated, WiDrive. Result shows that WiDrive is reliable as it successfully mapped to the GPS, and passed the crash accelerometer test at different distance. If given a chance to improve and implement in a wide scale testing, an exponential benefits can be achieved.

Abstract: A management method of scheduling the parking spaces in adjacent parking lot uniformly has been proposed to solve the growing problem of parking pressure caused by the increasing number of motor vehicles in cities. This method uses GSM network to collect the parking space’s status in adjacent parking lots, receives SMS or web query from owners, and shows the messages of each parking lot to them. Users could avoid the busy parking lots to parking their cars in the free parking lots relatively due to the query information, and can also obtain the right of parking spaces by appointment. The rock-bottom detection of each slave node by master node via RS485, Mater nodes transfer the detection messages to management system via GSM. The result shows this design could make use of existing parking resources. It is a good way to solve the problem of ‘Parking hard’.

Abstract: In this paper a multi-function GPS data collection system based on GSM Short Message Service is designed. By using a self-defining communication protocol, data transmission between a mobile terminal and a monitor center is achieved. The information collected by the mobile terminal is displayed upon the monitor center and a path of the mobile terminal can be shown on Google Earth. Experimental results show that the system not only reaches a satisfying positioning accuracy, but also runs robustly at a low-power state.

Abstract: The development of satellite communication technology has brought the Vehicle tracking systems to the day-to-day life of the common man. Today GPS fitted cars, ambulances, fleets and police vehicles are common on the roads. All the existing technology can support only tracking the vehicle place and status. No such systems have implemented emergency alert during accidents, using smart phone. Real time vehicular tracking system incorporates a hardware device installed in the vehicle and a remote Tracking server. The information is transmitted to Tracking server using GSM/GPRS modem on GSM network by using SMS or using direct TCP/IP connection with Tracking server through GPRS. Tracking server also has GSM/GPRS modem that receives vehicle location information via GSM network and stores all this information in computer database. This information is available to authorized users of the system via website over the internet.The embedded device fitted with “sensors”. The sensors used are to provide Automated Emergency Alert in case of accident (Inform nearby Police, Hospital and Owner through SMS), Identification of Halts and Duration, Emergency Message Display in Centralized computer, Automatic update of Emergency number, Fuel Tank Pilferage Monitoring and Distance and Speed computation. The data from the sensors are transferred to centralized server through GSM enabled device. GPS device is used to track the vehicle locations in latitude and longitude. The GPS device is received raw satellites data in this data is not understandable first we convert raw data to digital form and transmitted to centralize computer. Each licence vehicle owner can access the data using web service and can retrieve all the real time data and stored previous data in database. Because whole Proposed system control in a single chip so proposed system allows for the stability, equilibrium, less resource use and sustainability of a tracking system and save of the people life.

Abstract: This paper proposes a mobile phone based security and control system for home appliances through SMS/Bluetooth. It focuses on controlling home appliances remotely, and providing security with good graphical user interface. The system uses GSM technology, providing ubiquitous access to the system for security and automated appliance control from anywhere around the globe. The system provides security against intrusion using a smarter digital lock which notifies owners in case of an unauthorized via SMS message, as well as facilitates both short and long-range device control using Bluetooth or SMS technology. Rather than a conventional method of sending an SMS message to control devices, a graphical user interface is designed using Python S60 language for ease of use. The control signals in the form of SMS messages are encrypted and restricted to unique mobile phones or SIM cards for improved security.

Abstract: This streetlight monitoring system is aimed at preventing unnecessary energy wastage by applying the GSM (Global System for Mobile Communications) technology. This system consists of two parts: the monitoring centre and the terminal nodes. The Siemens TC35 GSM module is used to send and receive short messages and it is installed in the monitoring centre and each streetlight. ATmega168 is used to determine whether or not it is necessary for the streetlights to be turned on, and then it executes commands from the control centre. When the sky is bright enough for drivers, the streetlights will automatically turn off. Also, if some streetlights are broken down, the TC35 GSM module will send an alarm short message to the monitoring centre and maintenance personnel will repair the lights as soon as possible. Thus, maintenance personnel will no longer have to make time-consuming visits to check up on the function status of every streetlight. All information is presented in the monitoring computer which is programmed in LabVIEW. The workman can easily turn on or off any streetlight by clicking on the screen.

Abstract: Landslide is one of the most serious natural disasters, forecast and early warnings are important. The SMS backhaul of WSN monitor system is discussed in this paper. After analyzing the transmission system of WSN at present, this paper intend to combine GPRS-Internet, SMS-PP and SMS-CB to pass early warning back to inhabitants, so as to further ensure the reliability and instantaneity. In order to send early warning to every person in landslide zone, several situations are considered. With the real-time monitoring system and extensive early warning backhaul, the damages and losses would be reduced.

Abstract: This research is an investigation of the causes of call drops in a GSM network in Benin City, Nigeria. Call drop is inability of call to connect and go through the network successfully. For a drop call the subscriber does not enter into a queue for potential assignment. In this work, a drive test was conducted over a period of three months (March, April and May 2010) in cells around Benin City area. The drive test was conducted with the use of test mobile. A test mobile is a kit comprising mobile phone, drive testing proprietary software called TERMS on a laptop computer and GPS (global positioning system). A total of twenty seven cells out of forty cells around Benin City area were discovered to have severe call drops leading to very poor network performance. The problems that caused the call drops were determined and corrected leading to high improvement in call performance.
