Power conservation for maximizing the lifetime of the limited battery powered ad hoc networks are one of the most important factors in a network design. Transmitting at high power may assure network connectivity but sacrifice network lifetime and increases the interference as well. Meanwhile transmitting at lower power reduces the interference on the expense on network robustness. We investigate the minimum transmit power to optimize those goals taking into consideration the effect of several network design parameters such as the data rate, node spatial density and traffic load. This was done considering a cross layer design optimization between the parameters of physical (PHY) and Medium Access Control ( MAC) layers to show how they are related considering the route QoS in terms of a given threshold for the probability of error at the end of a multi-hop route. We motivate the use of spreading codes in the physical layer in wireless ad hoc networks. We show that the use of spreading codes together with spatial reuse can achieve a flexible achievement tradeoff among different parameter metrics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
