Several systems based on many-to-many channel emulators have been built, however these systems rely on either a simple deterministic channel model such as free-space path loss, or a general stochastic channel model, where the only input determining channel characteristics is node distance. In order to more thoroughly test radio and protocol performance in a wider variety of scenarios, it is necessary to incorporate site-specific channel characteristics. We have experimented with using RF ray-tracing software to model site-specific real-world environments at the University of Maryland (UMD) campus. We have used these channel model predictions to drive two different types of channel emulator-based wireless testbeds, and have compared results from those testbeds to field tests in the actual locations. Finally, we have experimented with various levels of detail in our environment models to evaluate the payoff, in terms of realism, for spending extra time and resources to build highly-detailed environmental models.","PeriodicalId":379382,"journal":{"name":"MILCOM 2013 - 2013 IEEE Military Communications Conference","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128798591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dynamic routing is implemented by integrating a spectrum-aware backpressure-like algorithm with shortest-path routing to improve both the average delay and the achievable throughput under hard deadline constraints. CREATE supports spectrum adaptability by establishing asynchronous negotiation and coordination channels instead of a dedicated common control channel. For end-to-end experimental evaluation of CREATE, we propose NEST, a Network Emulator and Simulator Testbed, to deploy and experiment with cognitive radio (CR) networking protocols and applications on real programmable radios. NEST combines a low-cost and scalable simulation environment with realistic hardware performance to provide high fidelity and repeatable CR network experiments. Our experimental results characterize the effects of network topology and physical channel on the spectrum agility, situational awareness and resiliency across the protocol stack in multi-hop CR networks.","PeriodicalId":379382,"journal":{"name":"MILCOM 2013 - 2013 IEEE Military Communications Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129911320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When the vehicles communicate over a wireless ad hoc network, network connectivity may need to be preserved during the reconfiguration process. In addition, achieving the network topology associated with the desired final physical formation can then enable the physical formation to be achieved through a variety of formation control algorithms. In this paper, we focus on the problem of anonymous reconfiguration in which any vehicle in the initial formation of the system can be assigned to any of the positions in the final formation. We consider a key unsolved subproblem, which is how the nodes in the initial formation should be mapped onto the nodes in the final formation before the formation is reconfigured, while taking into account the needs to preserve network connectivity. We develop algorithms to solve this problem based on optimal and suboptimal graph-matching algorithms. We then apply these techniques with previously developed techniques to plan node movement to reconfigure the network topology while preserving network connectivity at all times. The performance of these techniques is evaluated via simulation.","PeriodicalId":379382,"journal":{"name":"MILCOM 2013 - 2013 IEEE Military Communications Conference","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129203024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent developments in cognitive radio (CR) and dynamic spectrum access (DSA) network have also brought much attention to modulation detection of unknown radio frequency (RF) signals. It is well known that using second-order cyclostationary features, BPSK modulation can be easily distinguished from higher order modulations such as QPSK and QAM. However, these higher order modulations exhibit similar second-order cyclostationary features, thus theses features cannot be employed to further distinguish higher order modulations. To accurately detect and classify higher order modulations, higher order features such as higher order cumulants are desired. In this paper, we build a automatic blind hierarchical modulation detector to successfully classify the modulations of RF signals. Moreover, we use software defined radio (SDR) to implement and demonstrate a practical blind hierarchical modulation detector which can accurately distinguish among three popular modulations, i.e., BPSK, QPSK and 16-QAM. Specifically, second-order cyclostationary features using detailed spectral coherent function (SOF) are applied first to distinguish between BPSK modulation and non-BPSK modulations (e.g., QPSK and 16-QAM modulations) at first level of the hierarchical modulation detector. Next, the fourth-order cumulant feature is employed to the non-BPSK RF signals to distinguish between QPSK and 16-QAM. The SDR based modulation detector does not require any priori information of the RF transmission, and executes accurate detection in real time. Demonstrations in AWGN channel and realistic multi-path fading channel confirm the effectiveness and efficiency of the proposed modulation detector.","PeriodicalId":379382,"journal":{"name":"MILCOM 2013 - 2013 IEEE Military Communications Conference","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114203342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This may require adaptation of the sampling rate of different sensors accordingly. However, current solutions for optimal rate allocation do not consider the importance (or criticality) metric of sensors, which can cause the algorithms to ignore critical nodes altogether. In this paper, we address this challenge by developing a centralized algorithm that attempts to maximize the overall quality of information for the whole network given the utility functions and the importance rankings of sensor nodes. We also present a threshold based heuristic that may help system administrators to tune the algorithm to prevent omission of highly important nodes at critical times. Extensive evaluation of our algorithm in simulation for various scenarios shows that it can quickly adapt the sampling rate in response to the changed importance of sensor nodes.","PeriodicalId":379382,"journal":{"name":"MILCOM 2013 - 2013 IEEE Military Communications Conference","volume":"20 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113991021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
