The paradigm introduced in this paper is based on the innovative idea of Mobile Code which has been implemented on a test bed at the Adaptive Risk Management (ARM) Laboratory at the University of New Brunswick (UNB) [1]. Networks based on Information and Communication Technology (ICT) are revolutionizing the world and their perpetuation is leading to the dependence of critical infrastructures on the reliability of these networks, the integrity of the information flowing and stored on these networks, and on the availability of these information networks through the Internet [2]. In order to deal with this, the idea of Mobile Code is introduced in this paper as the relatively new concept of real-time in-Network programming that occurs when certain conditions are met. Through the application of the Mobile Code approach networks of networks [3] can achieve an increase in resilience from failure due to attacks and furthermore, attain self- management capabilities which is a much needed characteristic in today's Network Systems and protocols.","PeriodicalId":339313,"journal":{"name":"2008 IEEE International Networking and Communications Conference","volume":"2015 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127708141","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, the low-complexity detection in conventional TR scheme is achieved at the expense of 50% energy/rate loss. In this paper, an energy-efficient TR signaling and detection scheme is presented with the aim to improve the performance of conventional TR impulse radio UWB system. The proposed scheme is a combination of the conventional TR scheme and the differential TR scheme. The simulation results validate that the proposed TR scheme utilizes 1.76 dB less energy per bit and recovers 25% rate loss of conventional TR scheme, while maintaining the same BER performance. Further, the proposed ATR scheme improves the BER performance by about 2 dB using simple averaging of the reference pulses.","PeriodicalId":339313,"journal":{"name":"2008 IEEE International Networking and Communications Conference","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124503561","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 the first release of high speed downlink packet access (HSDPA) specification the highest supported modulation scheme, 16 quadrature amplitude modulation (16QAM), might not be efficient enough to fully exploit the superior signal quality offered by the femto base stations making the use of a higher order modulation desirable. This paper presents a performance evaluation of using higher order modulation scheme, namely 64QAM, with HSDPA in a combined single frequency macro and femto cell scenario with advanced receivers used at mobile terminals. The impact of femto cells and 64QAM is also analyzed as a function of indoor user penetration. The analysis is done using dynamic system level simulations.","PeriodicalId":339313,"journal":{"name":"2008 IEEE International Networking and Communications Conference","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120851991","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}

The use of variable step-size in the adaptation process of least mean switched error (LMSE) algorithm (VSS-LMSE) is investigated. The switching algorithm consists of applying the least mean fourth (LMF) algorithm and switching to the least mean square (LMS) algorithm when the absolute value of error is greater than 1. The LMSE algorithm with a fixed step-size usually results in a trade-off between the residual error and the convergence speed of the algorithm. The VSS-LMSE algorithm presented here will eliminate much of this trade-off. In this paper the MSE of using the VSS-LMSF algorithm in the adaptation process of system identification over a dispersive channel is investigated. The step-size variation makes it possible for the VSS-LMSE algorithm to converge faster and to a lower steady state error than in the fixed step-size case. Moreover the proposed VSS-LMSE algorithm has a much lower steady state error than that in the case of VSS-NLMS algorithm.","PeriodicalId":339313,"journal":{"name":"2008 IEEE International Networking and Communications Conference","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134070533","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}

Existence of different network interfaces in multi homed devices enables them to seamlessly roam across heterogeneous networks. These vertical handovers however, causes to affect the TCP connections. Many solutions exist that handle this problem caused by mobility of the nodes. However, current mobility management solutions either require support of additional entities in the network or require changes in current implementation of TCP. This paper argues that mobility management service can effectively be provided without requiring the support of additional entities in the network and without changing the current implementation of TCP. On the basis of this principle, we present an end-to-end mobility management framework (EMF) that overcomes the limitations of current mobility management solutions and provides a richer set of mobility services such as location updates, soft handover, willful handover, etc.","PeriodicalId":339313,"journal":{"name":"2008 IEEE International Networking and Communications Conference","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133888491","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}
