In this paper, we study the effect of peak interference power constraint on outage probability and transmission time of packets for secondary user (SU) in a spectrum sharing environment. In the considered cognitive radio network scenario, a secondary user transmitter sends its packets over a Rayleigh fading channel. In combination with the analysis of time out characteristics, queueing models are...
In this paper, we derive the probability density function and cumulative distribution function of packet transmission time in a spectrum sharing system. In combination with the time-out characteristics of packets, we further study the outage probability and average transmission time under peak power interference constraint over Nakagami-m fading channel. Especially, we employ the M/G/1 queuing model...
The problem of modeling latency in a convergecast wireless sensor network secured using various key predistribution schemes is addressed in this paper. The proposed analysis for latency follows a queuing-theoretic approach, wherein traffic occurs as a Poisson process in time distributed uniformly across a deployment area. The proposed approach is employed to analytically evaluate the latency performance...
