摘要
We consider the problem of throughput modeling of multi-hop wireless networks with cellular overlay using simple forwarding strategies in the upstream. Considering the effect of shadowing and distance loss, we derive a closed-form formula for the probability density function of power and interference at each receiver and compare the numerical and simulation results for different path loss parameters. When link efficiencies of all connections are the same, relaying packets increases the mean and variance of interference and hence results in higher outage probability. However, using capacity enhancing techniques at the physical, link and network layers, we are to benefit from the reduced transmit power due to multihop operation and further trade off power for additional capacity.
