This paper presents a new security protocol that provides conversation authentication, integrity, intrusion prevention and anti-replay protection. The protocol uses two methods in order to meet these requirements: the last MAC method and an authentication handshake. The protocol has been implemented in TinyOS in two layers of the communication stack: the MAC and Authentication layer. The MAC layer is the implementation of the last MAC method and the Authentication layer generates and verifies the four messages exchanged during the authentication handshake. Authentication and Anti-replay Security Protocol has been tested with TOSSIM in various attack scenarios and has proved that it is able to reject malicious attempts to communicate with the network nodes.","PeriodicalId":152012,"journal":{"name":"2010 Fifth International Conference on Systems and Networks Communications","volume":"48 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120868739","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}

In LTE system, some virtual subcarriers at the borders of the allocated bandwidth are used which invalidates the conventional power allocation schemes for uniformly placed reference signal. Further, RS for multiuser are multiplexed by cyclic shift. Constant power is required within one step of cyclic shift which adds more constraint on power allocation. The proposed RS power allocation scheme minimizes the mean square error (MSE) of the least square (LS) estimates considering the effect of virtual subcarriers and the constraint due to the cyclic shift. The effectiveness of the proposed scheme is verified by simulation results, showing that 2 dB SNR gain is achieved as opposed to conventional scheme with equal power reference signal.","PeriodicalId":152012,"journal":{"name":"2010 Fifth International Conference on Systems and Networks Communications","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122362806","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}

Advantages of bare PC computing include elimination of overhead due to the OS, and immunity against attacks targeting OS vulnerabilities. We evaluate the performance of a bare PC SIP server by determining its throughput and latency in a dedicated test network using the open source SIPp workload generator to generate requests for registration (register, register update, and register logout operations), proxying (invite and invite-not-found operations) and redirection (invite redirect operation) with and without authentication. We also report internal timings for the server. The performance of the server is then compared with the OpenSER and Brekeke SIP servers running on Linux and Windows respectively. Our results show that the bare PC SIP server has low cost for internal SIP-related operations, higher throughput than the Windows server, and higher or equal throughput than the Linux server except in the case of redirection. Its latency is more than that of an OS-based server only in the case of invite with authentication and invite-not-found without authentication.","PeriodicalId":152012,"journal":{"name":"2010 Fifth International Conference on Systems and Networks Communications","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125680273","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 paper addresses the problem of energy saving in an IEEE 802.15.4a large-scale full mesh WSNs based on UWB technology. It presents a network architecture to facilitate resource sharing and to ensure load and energy balancing. With a particular focus on medium access control (MAC) protocols, we propose a multi-channel MAC protocol, Prioritized Multi-Channel Multi-Time slot MAC protocol (PMCMTP), that due to its intelligent management of spectrum resource and time slots, can simultaneously improve energy efficiency and network quality-of-service (QoS). To prove energy efficiency and QoS support of PMCMTP, we implement it in a discrete-time simulator built in JAVA. Simulations results show that PMCMTP succeeds to save energy and to enhance network QoS with a low overhead.","PeriodicalId":152012,"journal":{"name":"2010 Fifth International Conference on Systems and Networks Communications","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132974498","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}

It helps users to intuitively establish communication between local devices. Accessing devices such as public terminals raises several security concerns in terms of confidentiality and trust. To overcome this issue, NFC can be used to leverage the trusted-computing protocol of remote attestation. In this paper, we propose an NFC-enabled Trusted Platform Module (TPM) architecture that allows users to verify the security status of public terminals. For this, we introduce an autonomic and low-cost NFC-compatible interface to the TPM to create a direct trusted channel. Users can access the TPM with NFC-enabled devices. The architecture is based on elliptic-curve cryptography and provides efficient signing and verifying of the security-status report. As a proof-of-concept, we implemented an NFC-enabled TPM platform and show that a trust decision can be realized with commodity smart phones. The NFC-enabled TPM can effectively help to overcome confidentiality issues in common public-terminal applications.","PeriodicalId":152012,"journal":{"name":"2010 Fifth International Conference on Systems and Networks Communications","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130810443","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 compare the simulation results for four scenarios: when the event is stationary, moving randomly, moving with simple 4 path and boids path. The simulation results have shown that for the case when event is moving randomly the performance is the worst in the four scenarios. The characteristic of goodput decreases with the increase of number of sensor nodes. In the case of boids model, the gooput is unstable when the Tr is lower than 10 pps. The consumed energy characteristic increases with the increase of Tr. Simulation results show that the consumed energy of random movement is the worst among four scenarios. The consumed energy of boids model is the lowest in four cases. This shows that the event movement with boids model can decrease the consumed energy in the large scale WSNs.","PeriodicalId":152012,"journal":{"name":"2010 Fifth International Conference on Systems and Networks Communications","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126281240","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}

However, recently, two new algorithms, searching for better load balancing and presenting superior performance than Dijkstra´s when submitted to an uniform traffic load, were proposed, the Restricted Routing Technique (RRT) and the Best among the Shortest Routes - (BSR). This work evaluates the performance of these algorithms under a non-uniform traffic load. For each topology studied were observed specific characteristics of the impact of the non-uniform traffic load for each routing algorithm. Overall, performance evaluation results showed that the algorithm BSR achieves for all topologies studied superior performance in terms of blocking probability and fairness.","PeriodicalId":152012,"journal":{"name":"2010 Fifth International Conference on Systems and Networks Communications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127596216","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}
