Throughput-Lifetime Tradeoffs in Multihop Wireless Networks Under an SINR-Based Interference Model

Free registration required

Executive Summary

High throughput and lifetime are both crucial design objectives for a number of multi-hop wireless network applications. As these two objectives are often in conflict with each other, it naturally becomes important to identify the tradeoffs between them. Several works in the literature have focused on improving one or the other, but investigating the tradeoff between throughput and lifetime has received relatively less attention. The authors study this tradeoff between the network throughput and lifetime, for the case of fixed wireless networks where link transmissions are coordinated to be conflict-free. They employ a realistic interference model based on the Signal-to-Interference-and-Noise Ratio (SINR) which is usually considered statistically sufficient to infer success or failure of wireless transmissions.
