Mobile Phone based Home Security System

Abstract

The importance of home security 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 microcontroller over generic interface such as USB so that derived system can gain advantages of significant features of both. 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 work individually fine. 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 etc. Moreover it discusses about challenges of debugging embedded program and pit falls of Simulators. It also explained platform and framework limitations such as writing embedded program that can run under 368 bytes of RAM, incompatibilities of interfacing digital circuits, limitations of AT commands, J2ME security restrictions, its feature dependency with various mobile phones and limitations of peer to peer video streaming. 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, miss synchronization and use of arrays larger than 95 bytes. However it also concludes that people can monitor their properties anytime, anywhere using their own mobile phone. Besides they can automate home appliance and receive security alerts. It also shows that the research is successfully able to achieve its objectives such as reliability, interoperability, portability, user-friendliness, platform independency and low cost. Further it converse about possible future enhancements such as power line communication, interrupts routines, wireless communication like ultrasound or Bluetooth with their possible security concerns. Further it encourages future researches to do more and more explorations on mobile based embedded applications.
