a typical radio frequency identification system (rfid) includes one reader and a number of tags. the reader transmit to commands to the tags with interrogation radio signals, and tags receive the command and then respond with their identification. readers with interrogation signals can read tags’ responses. in rfid systems, when multiple tags respond to one reader simultaneously, tag collision ...

In this paper we combine Hardware Transactional Memory (HTM) with Read-Copy-Update (RCU) to implement highly scalable concurrent balanced Binary Search Trees (BSTs). The two key features of our approach are: a) read-only operations require no synchronization or restarts and b) tree modifications are first performed in private copies of subtrees, then HTM is used to validate their consistency, a...

B-trees have been ubiquitous for decades; and over the past 20 years, record-level locking has been ubiquitous in b-tree indexes. There are multiple designs, each a different tradeoff between (i) high concurrency and a fine granularity of locking for updates, (ii) efficient coarse locks for equality and range queries, (iii) run time efficiency with the fewest possible invocations of the lock ma...
