Mobile Embedded Hybrid Approach for Surveillance and Remote Controlling

Abstract

The importance of remote observation and controlling has been rapidly increased in recent years due to the evolution of mobility. Since mobile phones have become pre dominant at present, quite ubiquitous and increasingly sophisticated, the integration of the mobile phone and a surveillance system becomes more meaningful. This research explored possible ways of implementing such system over existing mobile phone infrastructure without any other third party service providers. However, this reveals the important of integration of mobile phone and embedded system over generic interface such as USB. Additionally, it addresses the design and the implementation of such home security system. It reveals about challenges that occurring while using several technologies simultaneously though they individually work properly. Further it converses about importance, limitations and challenges of synchronizing several functions together such as reading and writing via serial port of a microcontroller and using SMS and MMS listeners together. Moreover it discusses about challenges of debugging embedded program and pit falls of Simulators. It also explained platform and framework limitations such as limitation of memory, incompatibilities of interfacing digital circuits, limitations of AT commands, J2ME security restrictions, limitations of peer to peer video streaming, and feature dependency of mobile phones. However, possible solutions for them such as poling, synchronizing, interleaving, multithreading and level conversion are also discussed. Results conclude that data loses may occur because of buffer over follows due to concurrent usage, and miss synchronization. Besides responsiveness of the system is highly depend on the mobile network. It varies from seconds to few hours. Possible future enhancements such as interrupts routines, wireless communication like ultrasound and Bluetooth with their possible security concerns are discussed. However, this method connects software richness and mobility of mobile phone with the hardware connectivity of embedded system. Thus the derived system gain advantages of both.
