We consider $n$ nodes deployed in a square with $k$ nodes formulating multicast tree to employ network coding. In static unicast network, Liu et al. cite{Liujunning},cite{Liujunning2} have proved that the capacity gain with network coding is a constant without order change. In our work, we focus on the capacity gain with network coding in static multicast network, under the system model of Li cite{xiangyang}'s. Firstly, we modify the routing algorithm of multicast model and propose that the multicast capacity bound in cite{xiangyang} is just a theoretical result but not very tight in practical scenario. Then in static multicast transmission we calculate the probability of existing the butterfly model to employ network coding. Our result shows that there is no order change of the capacity. Finally, We prove that the bound of the capacity gain with network coding is $frac{tau}{sqrt{2}}$, where $tau=frac{sqrt{3}}{2}cdottau(2)$, and $tau(2)$ is a constant in dimension two, when network coding is applied to static multicast network.","PeriodicalId":6405,"journal":{"name":"2010 IEEE International Conference on Communications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78116315","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}

For a given sender-receiver distance, this differential capture capability of a receiver leads to two distinct interference ranges (ri ) around the receiver, and its value is much smaller when the sender's frame arrives earlier. This feature also suggests a possibility of increased spatial reuse by allowing the (secondary) nodes outside the primary receiver's ri to communicate concurrently once the primary receiver starts its DATA reception. In this paper, we propose a liberal carrier sensing (LCS) scheme wherein some already available information at an otherwise 'exposed' receiver are exploited to help decide when it is safe to respond to a secondary transmission request. The proposed modification in the carrier sensing approach results in a significantly improved spatial reuse, thereby increasing overall system throughput. Our simulation studies show that, compared to the conventional carrier sensing scheme with differential capture capable receivers, the end-to-end TCP throughput with LCS can be improved by more than 20% in regular topologies and up to about 9% in random topologies.","PeriodicalId":6405,"journal":{"name":"2010 IEEE International Conference on Communications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77985790","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}

But RSSI suffers significantly from the multi-path phenomenon and other environmental factors. Hence, the localization accuracy drops dramatically in a large tracking field. To solve this problem, this paper introduces one more resource, the dynamic of RSSI, which is the variance of signal strength caused by the target object and is more robust to environment changes. By combining these two resources, we are able to greatly improve the accuracy and scalability of current RF-based approaches. We call such hybrid approach COCKTAIL. It employs both the technologies of active RFID and Wireless Sensor Networks (WSNs). Sensors use the dynamic of RSSI to figure out a cluster of reference tags as candidates. The final target location is estimated by using the RSSI relationships between the target tag and candidate reference tags. Experiments show that COCKTAIL can reach a remarkable high degree of localization accuracy to 0:45m, which outperforms significantly to most of the pure RF-based localization approaches.","PeriodicalId":6405,"journal":{"name":"2010 IEEE International Conference on Communications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78140287","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}

On the other hand, for smooth upgrading, NG-PON is desired to be backward compatible with the current TDM PONs where data rates of ONUs remain unchanged. Thus, both high-rate ONUs and low-rate ONUs may coexist in NG-PON. The key parameters of bandwidth allocation in this multi-rate multi-wavelength network include achieving fairness among all ONUs, encouraging low-rate ONUs to increase their data rates, and utilizing wavelength resources efficiently. This paper illustrates contributions in three main aspects. First, we define rate-dependent utilities for ONUs, which serve as the basis for bandwidth arbitration among low-rate and high-rate ONUs. Second, to achieve fairness among ONUs, we employ water-filling idea and formulate a utility max-min fair bandwidth allocation scheme. Third, to efficiently utilize the wavelengths, we map the resource allocation problem in multi-wavelength PON into a multi-processor scheduling problem and employ a heuristic algorithm to address the NP-hard wavelength assignment problem.","PeriodicalId":6405,"journal":{"name":"2010 IEEE International Conference on Communications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75960593","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}
