Abstract
Android smart devices are ubiquitous in our daily life and becoming valuable device with the capabilities of wireless networking that are typically used with an IEEE 802.11 access point. Ad hoc network provides facilities to access devices in infrastructure less system without a centralized approach. Due to the open source of the development platform, Android was recently selected to be a supported operating system within this evolving and maturing technology delivery paradigm. Android based smart devices are dynamically joined to each other and create an ad hoc network on their own. Android based Smart devices are able to communicate with each other without requiring a dedicated wireless access point. The main goal of this paper is to identify faces and communicate in real time using ad Hoc network of Android based smart devices. The problem of communication is authentication in ad hoc network of android devices. Our study propose face detection technique to provide the solution of authentication in real time communication. In this research we implement HaarCascade technique to detect faces in real time. we develop android application to communicate in real time and detect all faces of connecting ad hoc network. The proposed system have been implemented in android ad hoc network system for authenticate the devices using face detection technique. Application has been developed and tested in ad hoc network environment of android based devices.
