Traditional routing protocols deployed to provide communication among mobile nodes in wireless ad hoc networks (MANET) assume a trust and collaborating environment inside the network. However, this assumption is not always true and a hostile or unprotected environment can seriously affect the protocol and network performance. In this work two kinds of approaches are applied to a well-known routing...
Broadcasting is an effective means for disseminating information in wireless ad hoc networks. In this paper we propose a novel distributed broadcasting protocol in wireless ad hoc networks, which is based on an highly efficient metric for characterizing the importance of a node, with respect to its contribution in covering the local neighborhood. The protocol is reliable and achieves small communication...
A wireless ad hoc network that has no connection to the Internet can not use a public key infrastructure (PKI). Although an on demand distributed public key management to construct the PKI has been proposed, it cannot work without considering routing tables, since nodes broadcast a packet which contains routing tables. In this paper, we propose an on demand distributed public key management which...
