This change should provide significant advantages compared to legacy hardware radios: the ability to support multiple waveforms on the same device, to upgrade the waveforms on the device through software downloads, and to dynamically adapt modulation or other physical layer parameters to a wide range of channel conditions. However, taking full advantage of software radio turns out to require a broad change in communications systems. Affected hardware components include antennas, filters, A/D converters, and power amplifiers. Affected device-level software components include signal processing, timing control, inter-layer APIs, and security. The hardware architectures optimal for this software are not GPPs, DSPs or FPGAs, but an interesting hybrid among these approaches. At the network level, new MAC algorithms and topology management are needed to exploit the flexibility of individual nodes. In this talk I present a slice through these varied and interrelated systems and research challenges, taking a total systems view of software radio.","PeriodicalId":329300,"journal":{"name":"Symposium on Architectures for Networking and Communications Systems","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114801458","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}

Previous work has shown the benefits of connection locality-based scheduling on multi-core servers to improve L7-filter performance. However, we show that highly threaded hierarchical multi-core processors, such as the Sun Niagara 2 processor, accumulate imbalanced workload at each resource layer. This workload imbalance potentially offsets the benefits from connection locality. In addition, connection-locality-based load balance fails to work when network traffic is unevenly distributed.\u0000 In this paper, we propose an adaptive hash-based multilayer scheduler for a highly threaded hierarchical Sun Niagara 2 server. Our scheduler maintains connection locality and adaptively adjusts the scheduling to balance the real time workload. The original Highest Random Weight (HRW) hash guarantees the connection locality but only balances the workload over the number of different connections. We enhance the original single layer HRW into a hierarchical \"hash tree\" scheduler to balance the connection workload in accordance with the hierarchical processor architecture. We then optimize our multilayer scheduler to adaptively adjust scheduling decisions based on service time at each level, further improving the system load balance. Our scheduler is shown to increase the system throughput by 59.2% compared to the previously proposed connection locality optimization.","PeriodicalId":329300,"journal":{"name":"Symposium on Architectures for Networking and Communications Systems","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126673773","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}

Accompanied with this trend is the growing malicious activities against these mobile systems, such as information leakage, service stealing, and power exhaustion. Besides the threats posed against individual mobile users, these unveiled mobile devices also open the door for more serious damage such as disabling critical public cyber physical systems that are connected to the mobile/wireless infrastructure. The impact of such attacks, however, has not been fully recognized.\u0000 In this work, we show that mobile devices, even with the state-of-the-art security mechanisms, are still vulnerable to a set of carefully crafted attacks. Taking Linux-based cell-phones as an example, we show that this vulnerability not only makes it possible to attack individual mobile devices such as accessing unauthorized resources, disabling predefined security mechanisms, and diverting phone calls, but also can be exploited to launch distributed denial-of-service attacks against critical public services such as 911. Using the open multi-class queuing network model, we analyze in detail the consequence of these attacks against the 911 service in a large region and also present some unique characteristics of these attacks. We further discuss potential countermeasures that can effectively mitigate or eliminate these attacks.","PeriodicalId":329300,"journal":{"name":"Symposium on Architectures for Networking and Communications Systems","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126425106","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}
