WMPLS throughput efficiency in multipath Rayleigh fading environments



This paper studies the throughput efficiency of wireless multi-protocol label switching (WMPLS) applying data link automatic repeat request (ARQ), go-back-N (GBN) and selective repeat (SR) protocols, for reliable packet transmission. The paper investigates the impact of the packet size on the throughput efficiency of the ARQ protocol for a reliable service under different conditions of a multipath fading channel. This investigation addresses the probability of receiving a correct packet. An upper bound and a lower bound for this probability are suggested in the closed-form format. A novel numerical method to calculate the optimal packet size for GBN is also proposed in this paper.
