Mobile agent-based approach for efficient network management and resource allocation: framework and applications

Abstract: Agent programming technology has emerged as a flexible and complementary way to manage resources of distributed systems due to the increased flexibility in adapting to the dynamically changing requirements of such systems. A very promising application of this technology is related to the control of forthcoming networking systems which will represent a competitive marketplace with a multitude of vendors, operators and customers. Thus, new reference models have to be investigated in order to better satisfy users' requirements in a framework where resource allocation is provided under the control of different and often competing stakeholders (users, network providers, service providers, etc.). We believe that autonomy is one of the features that will characterize the behavior of agents in such environment: autonomous choices will be taken as the result of coordination among different cooperating software entities. Following this direction, we describe the efficient integration and adoption of mobile agents and genetic algorithms in the implementation of a valuable strategy for the development of effective market based routes for brokering purposes in the future multioperator network marketplace. The proposed genetic algorithm provides a kind of stochastic algorithm searching process in order to identify optimal resource allocation strategies. The agent-based network management approach represents an underlying framework and structure for the multioperator network model, and can be used to facilitate the collection and dissemination of the required management data, as well as the efficient and distributed operation of the algorithm. We also present some numerical results to assess the performance and operation effectiveness of our approach, by applying it in some test case scenarios.

Point-to-Multipoint Communication Enablers for the Fifth Generation of Wireless Systems

Abstract: 3GPP has enhanced the point-to-multipoint (PTM) communication capabilities of 4G LTE in all releases since the adoption of eMBMS in Release-9. Recent enhancements cover not only television services, but also critical machine-type and vehicular communications, following the backward-compatibility design philosophy of LTE. This article discusses the opportunity in the design and standardization of 5G to break with the existing paradigm for PTM transmissions in 4G LTE, where broadcast PTM transmissions were initially conceived as an add-on and pre-positioned service. 5G brings the opportunity to incorporate PTM capabilities as built-in delivery features from the outset, integrating point-to-point and PTM modes under one common framework and enabling dynamic use of PTM to maximize network and spectrum efficiency. This approach will open the door to completely new levels of network management and delivery cost efficiency. The article also discusses the implications of PTM for network slicing to customize and optimize network resources on a common 5G infrastructure to accommodate different use cases and services taking into account user density.

Remote management of retail petroleum equipment

Abstract: A network management system remotely manages a fuel dispensing network comprising a plurality of refueling stations each including several fuel dispensing assemblies. The network management functions include reconfiguring the fuel dispensing equipment, downloading software updates, monitoring the status and performance of the fuel dispensing equipment, performing diagnostic and troubleshooting procedures, and scheduling maintenance calls and other servicing activity in response to the diagnostic evaluations. The management application performs its various network management functions in conjunction with a plurality of dedicated software agents each resident at a respective refueling station.

Network management system

Abstract: The invention relates to a network management system for configurating and reading data and states of several network elements, such as telephone exchanges, of a telecommunication network by giving the network elements commands according to their internal command language when at least some of the network elements of the telecommunication network have mutually different internal command languages. The network management system of the invention comprises memory means (25) for storing parameters describing the command language of each network element, means for generating service requests (Rq) in a network element independent format, conversion means (21, 22, 23) for converting said network element independent service requests into commands according to the command language of the network element which is the target of service by means of parameters describing the command language of said network element, and means for sending the generated commands to the network element which is the target of service. The network management updates the parameter files automatically by giving the network elements a specific command which reads the internal data structures, such as syntactic, semantic and user help data, of any other internal command or command response of the network element.

Simulation Evaluations of an Autonomous Urban Air Mobility Network Management and Separation Service

Abstract: This paper presents an initial implementation of an autonomous Urban Air Mobility network management and aircraft separation service for urban airspace that does 1) departure and arrival scheduling across the network, 2) continuous trajectory management to ensure safe separation between aircraft, and 3) seamless integration with traditional operations. The highly-autonomous AutoResolver algorithm developed for traditional aviation was extended to provide these capabilities. An evaluation of this initial implementation was conducted in fast-time simulations using a dense, two-hour traffic scenario with Urban Air Mobility aircraft flying between a network of 20 vertiports in the Dallas-Fort Worth metroplex. When the spatial separation was reduced from 0:3nmi to 0:1nmi, the total de- lay decreased by 7:3%; when the temporal separation was reduced from 60s to 45s, the total delay decreased by 28:4%. The total number of conflict resolutions decreased by 26% and 17%, respectively. Furthermore, when a scheduling horizon greater than the duration of UAM flights was used (50min), most conflicts were resolved pre-departure producing ground delay. By comparison, when a shorter scheduling horizon was used (8min), most conflicts were resolved post-departure generating airborne delay. For all scheduling and separation constraints tested, AutoResolver prevented loss of separation from occurring. Urban Air Mobility operations have the ability to revolutionize how people and goods are transported and this paper presents initial research focusing on the high levels of autonomy required for an airspace system capable of scaling to handle significantly higher densities of aircraft.
