Peer management for iTrust over Wi-Fi Direct

This paper describes peer management for the iTrust peer-to-peer information publication, search and retrieval system using Wi-Fi Direct in a mobile ad-hoc network. We present the fundamental concept of the iTrust mobile ad-hoc network, the capabilities and limitations of Wi-Fi Direct on the Android platform, and our novel algorithm for managing peer connections. Specifically, we discuss how to acquire MAC addresses and associate peers with IP addresses in order to discover, connect and transfer data using Wi-Fi Direct on Android mobile devices. An Android device with Wi-Fi Direct hardware capabilities can automatically create and maintain a mobile ad-hoc network with nearby similarly configured mobile devices to enable peers to share information.
