Modeling study demonstrates reduced packet delivery delay in buffer-assisted multihop networks, suggesting a viable alternative for low-latency wireless applications.
Summary In this paper, a new relay selection scheme is proposed to reduce the end‐to‐end packet delivery delay for buffer‐assisted multihop decode‐and‐forward cooperative networks. The proposed method selects a relay node having more packets in the associated buffer and relay's proximity to the destination node. Mathematical expressions for the outage probability and average packet delay in Rician fading are obtained by modeling the system as a Markov chain. The proposed relay selection scheme has less packet delay as compared to the max‐link relay selection scheme with marginally higher outage probability. Thus, the proposed relay selection scheme is a good alternative to low latency wireless applications.
