One of the prime motivations was to reduce the costs associated with operating the relatively large number of different proprietary IP modems with similar performance and capabilities, performing similar functions, which are inefficiently consuming precious Military Satellite Communication (MILSATCOM) bandwidth. In March 2010, the Digital Video Broadcast (DVB) organization released DVB Document A155-1 in support of Second Generation DVB Interactive Satellite System (DVB-RCS2), with a similar objective brought forth by commercial satellite operators to reduce equipment costs by promoting economies of scale and increased interoperable solutions among IP modem vendors, while also lowering operational costs through increases in power and bandwidth efficiencies. Recently, the commercial market has started to express a need for transmission security (TRANSEC), which DVB-RCS2 aims to provide through a more effective and interoperable TRANSEC capability. The JIPM Interoperability Document was released in September 2010 through a Request for Information (RFI) to the IP modem industry. As a result of this exercise, the JIPM PMO has recognized an increased acceptance by the commercial industry in support of DVB-RCS2. This paper will evaluate the potential impacts of transitioning JIPM to DVB-RCS2, including an assessment as to whether DVB-RCS2 meets the objectives of the JIPM PMO1.","PeriodicalId":18720,"journal":{"name":"MILCOM 2012 - 2012 IEEE Military Communications Conference","volume":"140 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83423546","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}

We discuss stability improvements to such relay set election by adding a “resistance to change” weighting factor to help reduce change in election results. In particular, we examine a proposed extension to the Essential Connected Dominating Set (ECDS) algorithm that has been specified for use by both present mobile ad hoc network unicast and multicast protocols. We demonstrate temporal stability improvements in the ECDS relay set membership that can be achieved with a simple modification to the election algorithm. Our results are particularly important when dealing with frequently changing election metrics represented in the priority field such as density or link quality as a weight metric. By using several mobile models of networks undergoing link quality fluctuations we demonstrate significant improvements in stability of the backbone set. Our results also indicate that we can maintain good stability results while maintaining a small relay set membership size as compared to the unmodified algorithm.","PeriodicalId":18720,"journal":{"name":"MILCOM 2012 - 2012 IEEE Military Communications Conference","volume":"97 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80819575","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}

Low transmission power and simple communication protocol are significant obstacles for ULPSN to operate in the open spectrum. The DSA has been researched to solve this problem by assuming that coexisting systems can perfectly detect each other. However, this assumption is limited for ULPSN because detection of ULPSN in coexisting system is difficult due to sensitivity limitation of spectrum sensing. As a result, available spectrum is more scarce for ULP system than other coexisting systems. Thus, we derive a new Markov chain model of open spectrum access. Based on the Markov chain mode, we design a DSA scheme to maximize the energy efficiency and investigate the channel access and switch policy of the proposed DSA within the framework of partially observable Markov decision process (POMDP). The simulation results demonstrate that the proposed DSA scheme yields improved energy efficiency and lifetime compared to a random channel selection for ULPSN.","PeriodicalId":18720,"journal":{"name":"MILCOM 2012 - 2012 IEEE Military Communications Conference","volume":"13 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85276008","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}
