Trade-Off Between Cost and Goodput in Wireless
The authors study the cost of improving the good-put, or the useful data rate, to user in a wireless network. They measure the cost in terms of number of base stations, which is highly correlated to the energy cost as well as capital and operational costs of a network provider. They show that increasing the available bandwidth, or throughput, may not necessarily lead to increase in good-put, particularly in lossy wireless networks in which TCP does not perform well. As a result, much of the resources dedicated to the user may not translate to high good-put, resulting in an inefficient use of the network resources.
