Abstract: Multi-hop infrastructure-based communication is expected to play a vital role in supporting high data-rate multimedia access to mobile devices. The advantages are significant in highly mobile scenarios such as intra-vehicular networks. However, mobile nodes in these networks suffer from long authentication delays, which adversely affect the goodput. In this work, we propose two techniques to shorten the initial authentication delay without compromising the authentication process and overall security. One of the techniques, called fast authentication, admits data traffic temporarily through the network to the gateway and the immediate parent node of the joining node presents network-side authentication. The other technique, called prefetch-assisted authentication, allows the authenticated wireless nodes to prefetch and store the authentication vectors of the potential mobile clients. We investigate several unique features of our proposed schemes and find their performance to be suitable for infrastructure-based multi-hop wireless communications.
