Network coding not only improves TCP performance in lossy wireless multi-hop networks, but also changes other features of the TCP protocol such as the evolutionary process of the congestion window, which raises new issues about rate control, fairness etc. This paper analyzes the evolutionary process of network coded TCP against lossy links and error correcting coding. Ignoring the slow start phase,...
In this paper, we give a first example of identity based undeniable signature from NTRU lattice. We extend to the identity based setting the security model for the notions of invisibility and anonymity given by Galbraith and Mao in 2003 and we prove that our scheme is existentially unforgeable under the assumption in the random oracle model. We also prove that it has the unfogreability and anonymity...
Developing routing protocol for vehicular ad hoc networks (VANET) is a challenging task due to potentially large network sizes, rapidly changing topology and frequent network disconnections, which can cause failure or inefficiency in traditional ad hoc routing protocols. We propose an adaptive connectivity aware routing (ACAR) protocol that addresses these problems by adaptively selecting an optimal...
