We introduce a new interference management technique for wireless cellular networks when the base station (BS) has K antennas and there are M mobile stations (MS), each with a single antenna. Our interference management scheme takes advantage of multiuser diversity to transmit K independent data streams to K out of M mobile stations. The new approach achieves the dirty paper coding (DPC) capacity...
The desirable features of future optical high-capacity networks include higher stability, reconfigurability and security. In order to enable robust and self-managed automated operation, the network itself should be able to monitor the physical state of the network, automatically diagnose and repair the network, dynamically allocate resources, and redirect traffic. Optical performance monitoring can...
Management of the devices in a Wideband SATCOM enterprise Earth terminal facility (ETF) is currently fragmented among multiple systems, and some of these legacy systems provide only limited functionality. This paper describes the architecture of a consolidated system to manage the elements of an ETF. Such a system can offer a number of benefits. First, the ETF management system can provide a consolidated,...
In this paper, we propose a novel approach, which is termed heterogeneous intelligent filtering (HIF), for intelligent control and application data filtering in multi-domain heterogeneous networks. HIF creates intelligent gateways to rapidly and autonomously adapt the flow of information content to the changing mission needs and network characteristics. HIF employs a MANET management protocol (termed...
Studying the behavior of mobile ad-hoc networks (MANETs) is essential for predicting the performance of the network over the mission/application duration. In this work, we develop a framework for automating the network design to aid the user in tuning the design parameters as the mission progresses. We show the different states that the automated design manager (ADM) goes through to support different...
Hierarchical key management schemes would serve well for military applications where the organization of the network is already hierarchical in nature. Most of the existing key management schemes concentrate only on network structures and key allocation algorithms, ignoring attributes of the nodes themselves. Due to the distributed and dynamic nature of MANETs, it is possible to show that there is...
Automatic dynamic resource management (AutoDRM) architecture is a framework to efficiently manage shared resources in the tactical network environments without human operator intervention. The autoDRM architecture was developed to resolve the resource contention issues and to improve the quality of service in the tactical network environments. The information herein describes key components of the...
This paper presents a joint network management approach being studied for interfacing network management of different US future force networks. The approach attempts to pass information between the cipher text network managers of the army, the navy and the air force networks such that intelligent decisions can be made as traffic flows between these networks. As the first straw man approach, the paper...
The problem of anonymous wireless networking is considered when adversaries who monitor the transmissions in the network are also capable of compromising a fraction of nodes to extract network information. For a given level of network performance, as measured by network throughput, the problem of maximizing anonymity is studied from a game-theoretic perspective. The metric of anonymity considered...
With the proliferation of network management tools that adjust link and path characteristics to optimize network performance and health, TCP's are frequently incorporating path characteristic detection mechanisms to quickly adapt to the effects of these changes. Optimal TCP performance, including rapid adaptability, depends on, among other things, an accurate view of the of the bandwidth-delay product...
We consider the design of demand assigned multiple access (DAMA) algorithms that efficiently utilize limited RF uplink resources for packet switched military satellite communication networks. In previous work, we designed DAMA algorithms that optimized link layer efficiency and throughput while controlling delay and jitter. In this work we assess the ability of our DAMA algorithm to meet service level...
The net-centric vision for the global information grid (GIG) includes evolution toward Internet protocol (IP) based services. IP service profiles and in-service traffic flows in support of Warfighters in evolving deployments are highly variable, with end-to-end (E2E) flows typically spanning both terrestrial and satellite communications (SATCOM) networks. Communications planning, management and control...
The integrated waveform (DAMA UHF SATCOM), specified in MIL-STD-188-181C/182B/183B/185A, defines a TDMA communication system in an attempt to improve satellite bandwidth utilization over conventional SATCOM waveforms. To overcome some of the limitations of statically defined user communications (UCOM) services in MIL-STD-188-183A, the flexibility to assign services nearly anywhere within a frame was...
To fully utilize radio resources by intelligently filling in as much radio spectrum gaps as possible, the concept of cognitive radio network has been well accepted. A challenge inherent in this technology is how to build a mechanism that can allocate resource by learning and adapting to a specific radio transmission environment. In this paper, we propose a cognitive resource management scheme that...
