For human-driven as well as autonomous vehicles, one of the key requirements is continuous awareness of the surroundings to detect any potential threats (vehicles, pedestrians, wild-life etc.). This requires continuous cooperation between the vehicles by efficiently sharing safety information in a timely manner. However, this is a multi-dimensional and challenging problem due to the complex nature...
Energy conservation is a critical problem in wireless sensor networks (WSNs). Cross-layer design can provide energy efficiency through joint energy management and optimization. In this paper, based on two orthogonal modulation schemes- frequency shift keying (FSK) and pulse position modulation (PPM), we put forward a multi-layer energy efficiency optimal joint design approach for WSNs. Considering...
The traffic grooming, routing and wavelength assignment (GRWA) problem in wavelength division multiplexed (WDM) networks has been the focus of many studies over the past years. Under fixed grooming ratio and ring network topology assumptions, researchers have been able to provide exact or near optimal solutions. However, all practical cases in mesh networks have been addressed with heuristic algorithms...
We study the maximum throughput properties of dynamically reconfigurable optical network architectures having wavelength and port constraints. Using stability as the throughput performance metric, we outline the single-hop and multi-hop stability regions of the network. Our analysis of the stability regions is a generalization of the BvN decomposition technique that has been so effective at expressing...
Wavelength division multiplexing (WDM) networks have been adopted as a near-future solution for the broadband Internet. In previous work we proposed a new architecture, named enhanced grooming (G+), that extends the capabilities of traditional optical routes (lightpaths). In this paper, we compare the operational expenditures incurred by routing a set of demands using lightpaths with that of lighttours...
