As the 6LoWPAN devices are energy and resource constrained enabling mobility in these devices with the help of conventional host based protocols like MIPv6 is not suitable. Moreover, it may be possible in many scenarios that the mobile node (MN) moves far from the gateway (GW), while communicating with it. In this case the MN has to increase its transmission power, which may adversely affect its life time. In the proposed architecture static random deployed 6LoWPAN devices (SN) with same characteristics as the MNs, facilitate mobility such that the IP connectivity of the MN is maintained with minimum signaling at MNpsilas end. Thus this paper describes the link layer specific mechanisms needed between the SN and the MN to help it perform multi-hop communication with the GW. Moreover, it is designed keeping in mind the energy and resource constraint nature of SNs themselves. The signaling overhead for the SNs is determined through analytical modeling.","PeriodicalId":434891,"journal":{"name":"MILCOM 2008 - 2008 IEEE Military Communications Conference","volume":"517 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116236423","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 function will be achieved via static host nation agreements (HNA) and dynamic scanning to discover narrowband users of the MUOS band. HNA and scanning data are used to develop a notch mask that is applied to the MUOS waveform before transmission. This paper describes the successful development of a spectrum adaptive test terminal for the MUOS program. This terminal dynamically adapts a wideband spread spectrum waveform in order to cooperatively coexist with existing radio systems. The paper addresses the characteristics of a spectrum adaptive terminal and the modifications of a COTS waveform to enable operation in a spectrum adaptive mode. The interface between the communication waveform and spectrum scanning function is explained. The scanning algorithm, including radiometric integration, noise floor contour determination, and signal detection, is described in detail. The notching algorithm, and associated scanning interface, is also described. An example of a spectrum adaptive terminal, the General Dynamics U.S. Navy Digital Modular Radio (DMR) AN/USC-61 (C) is presented. In addition, methods of reducing the effects of narrowband interference upon the wideband waveform are described.","PeriodicalId":434891,"journal":{"name":"MILCOM 2008 - 2008 IEEE Military Communications Conference","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123991972","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}

While various attempts have been made to assess the impact of crowd density on suicide bomber effectiveness, the specifics of the actual crowd formation and orientation of the bomber with respect to the crowd has not been examined. A virtual simulation tool has been developed which is capable of assessing the impact of crowd formation patterns on the magnitude of injury and number of casualties during a suicide bombing attack. The tool examines variables such as the number and arrangement of people within a crowd for typical layouts, the number of suicide bombers, and the nature of the explosion including equivalent weight of TNT and the duration of the resulting blast wave pulse. The goals of the analysis are to determine optimal crowd formations to reduce the deaths and/or injuries of individuals in the crowd, to determine what architectural and geometric changes can reduce the number of casualties and injuries, and what is the correlation between variant crowd densities and formations with the weight and pulse duration of the explosives? Results indicated that the worst crowd formation is street (e.g. Zig-Zag) where 44% crowd can be dead and 71% can be injured (there is an overlap of injury and lethality), given typical explosive carrying capacity of a single suicide bomber. Bus and market crowd formations were found to be the best for reducing the effectiveness of an attack, with 24% and 26% crowd in lethal zone respectively and 58% and 54% in injury zones. Simulation results were compared and validated by the real-life incidents and found to be in good agreement. Line-of-sight with the attacker, rushing towards the exit, and stampede were found to be the most lethal choices both during the attack and post-explosion. These findings, although preliminary, may have implications for emergency response and counter terrorism. The paper also discusses additional capabilities that are being developed for the model.","PeriodicalId":434891,"journal":{"name":"MILCOM 2008 - 2008 IEEE Military Communications Conference","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124660444","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}
