wireless technology has undergone enormous growth. Surveys have shown that a new wireless subscriber signs up every 2.5 seconds. The number of cellular and personal communication system (PCS) users in the US has surpassed 100 million. However, wireless is not a recent technology. As early as 1793, wireless messages were transmitted in France using the optical telegraph. Stations consisting of a...

We present an open queueing network for analysing multi-layered window flow control mechanisms consisting of different subnetworks. The number of customers in each subnetwork is controlled bya semaphore queue. The queueing network is analysed approximately using decomposition and aggregation. The approximation was validated against exact numerical and simulation data, and it was found to have a...

Semaphores have been used extensively in programming concurrent tasks. Various extensions have been proposed for problems in which traditional semaphores turned out to be difficult to use. The extended semaphore primitives investigated here are based on the version of semaphores implemented in UNIX System V. Implementation issues are discussed and practical illustrations of their use are provid...

This paper describes our effort to improve the performance of the connection management subsystem of the OpenLDAP directory server. Two proposed architectures, the multi-listener and the lightweight listener architectures will be described and compared to each other in this paper. This paper will also describe our effort to improve the synchronization of multiple threads by introducing semaphor...

Using real-time image processing we have demonstrated a low bit-rate free-space optical communication system at a range of more than 20km with an average optical transmission power of less than 2mW. The transmitter is an autonomous one cubic inch microprocessor-controlled sensor node with a laser diode output. The receiver is a standard CCD camera with a 1-inch aperture lens, and both hardware ...
