Abstract— The ability of smart antennas to improve performance in a typically constrained ad-hoc network environment, has helped them garner significant attention over the last ...
An important problem in wireless ad hoc and sensor networks is to select a few nodes to form a virtual backbone that supports routing and other tasks such as area monitoring. Prev...
We present the Ad-hoc On-demand Secure Routing (AOSR) protocol, which uses pairwise shared keys between pairs of mobile nodes and hash values keyed with them to verify the validity...
Abstract. The RTS/CTS access scheme, designed to reduce the number of collisions in a IEEE 802.11 network, is known to exhibit problems due to masked nodes, the imbalance between t...
