Forming Optimal Topologies for Bluetooth-Based Wireless Personal Area Networks
This paper addresses the problem of determining an optimal topology for Bluetooth Wireless Personal Area Networks (BT-WPANs). In BT-WPANs, multiple communication channels are available, through a frequency hopping technique. The way network nodes are grouped to share the same channel, and which nodes are selected to bridge traffic from a...

On Guard: Producing Run-Time Checks From Integrity Constraints
Software applications are inevitably concerned with data integrity, whether the data is stored in a database, files, or program memory. An integrity guard is code executed before a data update is performed. The guard returns "true" just if the update will preserve data integrity. The problem considered in this paper...

A Space-Time Block-Coded OFDM Scheme for Unknown Frequency-Selective Fading Channels
This paper introduces a space-time block-coded orthogonal frequency-division multiplexing (STBC-OFDM) scheme for frequency-selective fading channels, which does not require channel knowledge either at the transmitter or at the receiver. The decoding algorithm is based on generalized maximum-likelihood sequence estimation. Due to the assumed orthogonality structure of STBC, the decoding rule...
