How to combine the both techniques is an interesting research. To our knowledge, this is still an open issue to implement the multicast routing in mobile ad hoc networks simultaneously employing the both mechanisms. Due to feedback explosion, most existing wireless network multicast protocols don't guarantee the reliable delivery. In this paper, we propose a novel reliable multicast protocol based on the opportunistic routing and network coding. Additionally, we also provide an ETX (expected number of transmissions) based cost metric formula of the multicast subgroup. Extensive simulation reveals that the performance of the novel presented multicast routing protocol outperforms the conventional multicast routing protocol in ad hoc wireless networks.","PeriodicalId":156036,"journal":{"name":"2010 IEEE International Conference on Wireless Communications, Networking and Information Security","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122716588","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 performance of this CDMA-based TDCS is investigated and discussed through theoretical analyses and simulation in Additive White Gaussian Noise (AWGN) and multi-path fading channels.

Our model is based on system operations using a batch arrival, and we suppose the batch size to be a random variable following a Pareto(c, α) distribution in order to capture the self-similar property. By using a discrete-time embedded Markov chain, we derive the probability generating functions of the number of data frames and batches for when the busy period begins and for when the system is in a busy cycle. Using the first and higher moments of the probability generating functions, we give the averages and the standard deviation for the system performance in the diffusion approximation for the operation process of the system. In numerical results, we show the performance measures such as the energy saving ratio, plus the average and the standard deviation for the handover ratio with different system parameters as examples.","PeriodicalId":156036,"journal":{"name":"2010 IEEE International Conference on Wireless Communications, Networking and Information Security","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114156876","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 software and hardware architecture of SIP phone which based on ARM920T core is demonstrated in this paper. The comparison of three voice codec algorithms including PCM, SPEEX and iLBC are implemented by porting these algorithms to embedded SIP phone platform. After several experiments, the result indicates that voice quality (e.g. MOS and R value) almost varies depending on the bandwidth, which also fit for theoretical analysis perfectly. Brings forward an effective conclusion that iLBC speech codec have excellent performance in low bit rates and it is superior to PCM and SPEEX encoding in abominable packet loss conditions.

Original blind separation method of DS-CDMA signals with ICA utilized only one sample value in each chip. However, in common DS-CDMA communication systems, the sample rate is much faster than the chip rate, so there are many samples during a chip interval. A method of average filtered blind separation of DS-CDMA signals with ICA is proposed in this paper. When noise is stationary, the method proposed could increase the input SNR of ICA greatly.

In this case, the performance of Discrete Fourier Transform (DFT)-based channel estimation will be degraded significantly due to dispersive distortion of actual channel impulse response (CIR). To deal with this problem, we analyze the effect of virtual subcarriers on channel estimation in theory and propose an effective channel estimation scheme in the present paper. The proposed method, which is based on Schur recursive algorithm, can expand channel frequency response (CFR) into all subcarriers with quite concise operations.
