— Directional antennas in multihop wireless networks offer a potential increase in the spatial reuse of the wireless channel. However, existing directional MAC protocols are not ...
This paper introduces T-Lohi, a new class of distributed and energy-efficient media-access protocols (MAC) for underwater acoustic sensor networks (UWSN). MAC design for UWSN fac...
Abstract. Implementations of cryptographic protocols, such as OpenSSL for example, contain bugs affecting security, which cannot be detected by just analyzing abstract protocols (e...
This paper presents the first analytical model to derive the saturation throughput of collision avoidance protocols in multi-hop ad hoc networks with nodes randomly placed accord...
In this paper, we present a fair-exchange electronic commerce (e-commerce) protocol, based on using an online trusted third party, that ensures fairness and prevents any party fro...
