The quality of service (QoS) measures of our consideration are a triplet of data rate, delay, and delay bound violation probability. Our target is to develop power control laws that can provide delay guarantees for real-time applications over wireless networks. The power control laws that aim at optimizing certain physical-layer performance measures, usually adapt the transmission power based on the channel gain; we call these ldquochannel-gain-basedrdquo (CGB) power control (PC). In this paper, we show that CGB-PC laws achieve poor link-layer delay performance. To improve the performance, we propose a novel scheme called hierarchical queue-length-aware (HQLA) power control. The key idea is to combine the best features of the two PC laws, i.e., a given CGB-PC law and the clear-queue PC law; here, the clear-queue PC is defined as a PC law that uses a transmission power just enough to empty the queue at the link layer. We analyze our proposed HQLA-PC scheme by the matrix-geometric method. The analysis agrees well with the simulation results. More importantly, our simulation results show that the proposed HQLA-PC achieves significant gain over the CGB-PC scheme, for tight delay requirements.","PeriodicalId":434891,"journal":{"name":"MILCOM 2008 - 2008 IEEE Military Communications Conference","volume":"39 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":"121448065","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}

NETCONF uses different transport layer protocols like secure shell (SSH), simple object access protocol (SOAP), or blocks extensible exchange protocol (BEEP) (IETF RFCs 4742 through 4744), and assumes availability of a high bandwidth network for successful configuration deployment. In a dynamic MANET tactical edge network consisting of fast-moving aircraft and terrain obscuration, conditions exist where traditional NETCONF may be less effective and eventually fails to provide guaranteed services to the war fighter. In this paper, we will look at the performance of NETCONF in a limited bandwidth constrained environment with periods of high packet loss. We will also consider the performance effect of using other compression algorithms and binary XML to reduce the amount of configuration data that is sent. Finally, we will study the usage of UDP-based NETCONF transport to improve the performance of NETCONF. By using UDP, data can be delivered more quickly than in a TCP-based transport. The performance analysis of such an airborne network as applied to different tactical scenarios with hundreds of assets will be accomplished through simulation.","PeriodicalId":434891,"journal":{"name":"MILCOM 2008 - 2008 IEEE Military Communications Conference","volume":"115 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":"116626629","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 is an effort to resolve current interoperability issues through the use of a standard protocol and provide IP connectivity between all airborne network platforms. However, large gaps exist between the current AN architecture and future envisioned net-centric capabilities. The dynamic nature of the AN topology, typically characterized by highly intermittent links and long link delays, limits the use and effectiveness of Internet-based standards and protocols. Developed separately, the delay tolerant network (DTN) architecture has been designed to address the needs of networks characterized by link intermittency, lack of end-to-end connectivity between end users, and high latency. While originally developed for deep space networking and inter-planetary communications, DTNs are highly applicable for sensor-based networks, terrestrial wireless networks, satellite networks, underwater acoustic networks as well as airborne networks. This paper addresses the specific challenges of establishing and maintaining reliable communications within an IP-based AN environment. In addition, this paper provides an overview of DTN, and details how this technology may be integrated into to the AN infrastructure in order to address the current issues affecting AN performance.","PeriodicalId":434891,"journal":{"name":"MILCOM 2008 - 2008 IEEE Military Communications Conference","volume":"2 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":"114803074","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}

Under such network dynamics, simulation has shown that the OSPF routing protocol performs poorly (e.g., increased overhead and data loss), but can be modified with dasiaMANET extensionspsila to better its performance. To provide complementary validation of these observations, this paper separately measures the routing protocol overhead generated by OSPF and its MANET extensions due to node mobility using an emulation testbed. The networking experiments were constructed using several off-the-shelf Linux workstations interconnected by Ethernet. Several modeling efforts were necessary to represent the network under testpsilas partial mesh connectivity, wireless interfaces, and node mobility on the immobile, non-wireless testbed. To validate these modeling efforts, the experimental results from the emulation testbed were cross-validated against OPNET simulation. For networks under test of increasing size, our emulation (and simulation) testing showed that the MANET extensions to OSPF consistently exhibited lower amounts of routing protocol overhead, and lower growth trends, when compared to OSPF. Our emulated results reaffirm previous simulation efforts.","PeriodicalId":434891,"journal":{"name":"MILCOM 2008 - 2008 IEEE Military Communications Conference","volume":"153 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":"116224299","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 showed that under clear atmosphere conditions the network communication energy can be modeled as the potential energy of an analogous spring system, which led to the development of distributed mobility control algorithms where nodes react to local forces exerted by neighbor nodes driving the network to energy minimizing configurations. This paper extends our previous work by including the effects of atmospheric attenuation in the channel. We show how our new formulation still results in a convex energy minimization problem. Accordingly, an updated force-driven mobility control algorithm is presented. Exponential forces are shown to appear on backbone nodes when atmospheric attenuation is present, which make them stay closer to each other to optimize backbone connectivity and reduce the network power usage. We present results in terms of power usage, network coverage and backbone connectivity and show how our updated mobility control algorithm allows the network to react to the effects of changing channel conditions.","PeriodicalId":434891,"journal":{"name":"MILCOM 2008 - 2008 IEEE Military Communications Conference","volume":"15 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":"116703253","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}
