“…Alternatively, SU can also perform spectrum sensing on a periodic basis. In [5], the statistics of extended delivery time (EDT) is evaluated with continuous spectrum sensing and semi-periodic spectrum sensing strategy, where SU continuously senses the target spectrum while transmitting and periodically senses for availability while waiting. Assuming continuous spectrum sensing, [6] evaluates the statistics of EDT of SU packet transmission under interweave fashion with adaptive modulation.…”

In cognitive radio communication, unlicensed secondary user (SU) can access underutilized spectrum of the licensed primary user (PU) opportunistically for emerging wireless applications. With interweave implementation, SU has to perform spectrum sensing on the target frequency band and waits for transmission if PU occupies the channel. This waiting time results in extra delay for secondary transmission. In this paper, the delay and throughput performance of secondary packet transmission is evaluated with slotted transmission protocol. We propose a discrete-time Markov model to characterize secondary slotted transmission process. Close-form solution of collision probability is obtained. We then carry out the queuing delay and throughput analysis based on a two-dimensional-finite-state Markov chain for small-size packet transmission. For large-size packets, the distribution function of extended delivery time for secondary packet transmission is also derived. Selected numerical results are presented to illustrate the mathematical formulas and to validate our research results. arXiv:1704.05159v1 [cs.IT] 18 Apr 2017With interweave implementation, SU performs spectrum sensing 1 for transmission availability. Ideally, SU continuously monitors the target spectrum while transmitting and waiting [4]. As such, no interference is introduced, at the cost of higher energy consumption and implementation complexity. Alternatively, SU can also perform spectrum sensing on a periodic basis. In [5], the statistics of extended delivery time (EDT) is evaluated with continuous spectrum sensing and semi-periodic spectrum sensing strategy, where SU continuously senses the target spectrum while transmitting and periodically senses for availability while waiting. Assuming continuous spectrum sensing, [6] evaluates the statistics of EDT of SU packet transmission under interweave fashion with adaptive modulation. Substantial amount of previous work has been carried out in developing practical accessing strategies with various PU and SU models. Assuming that all the primary users and secondary user share the same slotted transmission structure, authors in [7] design a novel MAC protocol based on optimal and suboptimal spectrum sensing and accessing strategies, where the optimization problem is formulated as a partially observable Markov Decision Process. [8] proposes optimal and suboptimal access protocol by maximizing the throughput of secondary transmission subject to the collision probability constrain, where secondary user adopts slotted transmission coupled with periodic sensing strategy. Authors in [9] propose an optimal sensing order selection strategy for multiple PUs' and multiple SUs' cognitive radio network, where the proposed sensing strategy converges to the collision free channel sensing order when the number of SUs' is less than the number of the channels. In this work, we consider a single PU and single SU cognitive communication scenario, where SU adopts slotted transmission strategy. Collision occurs with periodic spectrum s...

“…The total time required for the SU to complete a given packet transmission will include the waiting periods before accessing the channel, the periods of the wasted transmissions in case of non-work-preserving strategy, and the time used for the final successful transmission. In our previous work [12], we carried out a thorough statistical analysis on the resulting extended delivery time (EDT) [10] of secondary packets i.e. packets transmitted by the secondary user) for work-preserving strategy with perfect sensing.…”

“…In our previous work [12], we carried out a thorough statistical analysis on the EDT of secondary packet transmission with work-preserving strategy, and then applied these results to the secondary queuing analysis. Typically, work-preserving packet transmission requires packets to be coded with certain rateless codes such as fountain codes, which may not be available in the secondary system.…”

Cognitive radio transceiver can opportunistically access the underutilized spectrum resource of primary systems for new wireless services. With interweave cognitive implementation, secondary transmission may be interrupted by primary transmission. To facilitate the packet delay analysis of such secondary transmission, we study the extended delivery time of secondary packet transmission. In particular, we derive the exact distribution function of extended delivery time of a fixed-size secondary packet with non-work-preserving strategy, where interrupted packets must be repeated. We also analyze the effect of imperfect periodic sensing i.e. the secondary user periodically senses the spectrum for availability, with a chance of missing an available channel on a certain sensing attempt. These results complement previous work on work-preserving strategy with perfect sensing. Selected numerical and simulation results are presented for verifying the mathematical formulation.
