A synchronous multi-channel multi-access Medium Access Control (MAC) protocol for Wireless Local Area Networks (WLANs) is studied in this paper. The proposed protocol introduces an access control reservation scheme and requires a single radio per sta

In this paper we study a slotted WDM ring network architecture with a suitable access protocol that avoids both data channels collisions and destination conflicts and decreases the packets dropping probability. Our intention is to increase throughput

The fundamental problems of WDM networks are: (1) high rate of control packet loss and (2) high propagation delay for each (re)transmission. In this paper, we minimize the station randomness to access the control architecture introducing a collisions

The main investigation of this study is the performance optimization of a WDMA protocol suitable for a network architecture of passive star topology that uses the Multi-channel Control Architecture (MCA) and adopts asymmetric access rights over it. T

In this study we attempt to analyze a synchronous transmission WDMA protocol for passive star topology based on the propagation delay latency effect. The introduction of propagation delay constitutes a serious parameter for WDM networks performance b

A crucial issue in slotted OBS systems is the slot-generating traffic aggregation strategy as it impacts heavily on efficiency. The longer the assembly time, the better the fill level, at the penalty of delay, which may affect sensitive services. To
