“…We shall also investigate the impact of photonic network coding capabilities permitting mixing of different flows as stated in [49] on efficient resource usage and energy-aware routing over backbone networks in our future research. Furthermore, the generalization of heuristic approaches from small-scale networks to large-scale ones has certain issues and it may not be always the case that the generalization is predicted [50] , so we shall verify our heuristic approaches over larger-scale networks in our subsequent work.…”

The increasing energy consumption in backbone networks has been one of crucial concerns in Information and Communications Technology (ICT) sector. From a viewpoint of intelligent adaption, we propose Green Routing in Backbone networks with Bundled links, which is referred to as GRB2, to investigate the substantial power saving in a bundled link based backbone network for above enormous challenges from severe alarming statistics of the issues on economy, energy and environment. We formulate the above problems as Mixed Integer Linear Programming (MILP) models and develop power-aware greedy heuristics to solve them. We have investigated and compared the different characterizations of the solutions to the proposed problems by evaluating network power consumption including Power Saving Ratio (PSR) profile over time, PSR profile under different Maximum Cable Utilization (MCU) and PSR profile under different Bundled Sizes (BSs) and network performance including Powered-Off Cable Rate (POCR), Mean State Switching Times (MSST) and Mean Running Time (MRT) for various traffic demands during PPs and OPPs under different real backbone network topology scenarios compared with MSPF, SSPF, and HDEER. Experiment results show the different power-saving potential of these solutions once applied in the backbone network.INDEX TERMS Green networking, power awareness, traffic engineering, low power idle, bundled links

“…As seen in Section III-B, HAC is a heuristic approach based on forming clusters based on the exact solution of the linear model obtained from LPCHS. Hai et al [31] highlighted that sub-optimality is a serious concern in such approaches. The robustness against various input sizes of networks is the main problem in the performance evaluation of heuristic approaches.…”

Wireless sensor networks are a collection of tiny sensor devices powered by energy-scarce batteries. Depending on the nature of the application, those tiny devices might be deployed in areas that make it difficult to recharge or change their battery. Therefore, it is important to optimize the energy consumption of these devices to prolong their lifetime for as long as possible. Clustering is regarded as the most efficient approach to extend the lifetime of wireless sensor networks. This study proposes a novel method integrating cluster head selection and cluster formation to obtain as long a network lifetime as is possible. We employ a linear programming model to resolve the issue of cluster head selection and a Hierarchical Agglomerative Clustering (HAC) method to form clusters in the network. We evaluated HAC on different sets of inputs where we varied the position of the sink from the corner of the network to the center. HAC outperformed other existing clustering techniques for the first node death (FND) and half node death (HND) lifetime definitions in the cases where the sink is at the corner of the network. In the cases where the sink is located at the center of the network, HAC outperformed the other existing techniques for all definitions of network lifetime.INDEX TERMS Clustering, linear programming, network lifetime, power optimization, wireless sensor network.
