A collision-free with propagation latency WDMA protocol analysis

Analytical study of a synchronous WDMA strategy with propagation delay utilization

“…This fact provides a less costly implementation, since the required number of fixed receivers per station is less than in [11][12]. This fact, in conjunction with the effective access algorithm to improve the performance and the analytical study to derive the performance measures, consist the innovation of our study.…”

“…This means that the stations are not able to receive and process all control packets that are transmitted over the single control WDM channel, since the maximum control information processing rate is limited by the capabilities of the electronic interfaces. As a possible solution to the above problem, the use of the Multi-channel Control Architecture (MCA) which employs a number of control channels for control information exchange has been proposed [11][12]. In fact, the MCA provides significantly less control information processing overhead, since the control information is distributed into a set of control channels and its processing can be performed simultaneously in a parallel way.…”

“…In opposition to the studies [11][12], in this paper we assume that the number of control channels in the MCA is less than the number of data channels. This fact provides a less costly implementation, since the required number of fixed receivers per station is less than in [11][12].…”

An asymmetric access strategy with propagation delay analysis for bandwidth utilization improvement in WDM networks

“…Also, pre-transmission coordination schemes are followed to eliminate collisions like in [3], while priority scheduling algorithms to support differentiated services are introduced like in [4]. In [5] the Multi-channel Control Architecture (MCA) is proposed that employs a number of control channels for the control information exchange to overcome the electronic processing bottleneck [6]. In most of protocols, stations select randomly a data channel to transmit, which causes data channel collisions.…”

“…Also, we assume that round trip propagation delay is longer than data packet transmission time. So, propagation delay can be effectively exploited as acknowledgement time after the end of which we schedule data packet transmissions totally collisions-free [5].…”
