This letter proposes a design scheme for the powerefficient network with partial bandwidth path protection. The network with the proposed scheme utilizes resources efficiently, which leads to less power consumption. This scheme employs a Linear Programming (LP) approach to minimize power consumption by considering the number of active devices and capacity consumption. Simulations show that, with the partial bandwidth path protection, the proposed scheme saves more power than the conventional scheme, which minimizes the power consumption relying on capacity consumption.
This letter proposes a routing scheme to send a data set in units of bits rather than bits/s by considering the predefined transfer time, the period within which the data set should be transferred from the source node to the destination node, to minimize the energy consumed. The energy consumption is minimized with an optimal transfer time. The results show that routing at the optimal transfer time is, for the data set being sent, able to reduce energy consumption at least 7.7% for the networks examined.
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.
