Considering a GSM 900 based cellular multimedia network model, the dependency of system efficiency on the diversity of multimedia calls and handoff rate is first established; then, having determined an optimized value of protection ratio, it is established that, regardless of protection ratio value, the system's capacity depends upon the employed MAC (medium access control) protocol and handoff rate. Having confirmed numerical results by using LABVIEW 6.0 simulation software, it is concluded that, for any desired QoS level, the cellular multimedia network management requires intelligent optimization of the system efficiency and the system capacity that also depends on the employed MAC protocol and handoff rate.","PeriodicalId":337263,"journal":{"name":"2004 International Networking and Communication Conference","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133169353","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 has a self generating error control mechanism to achieve reliability using error correction. It also a has flow control scheme to avoid network congestion using a window mechanism. TCP is tuned to perform well in traditional wired networks, where packet losses are primarily due to congestion. However, with the increase in wireless communication, there is an immense need of adapting TCP to the wireless environment. Packet loss in wireless networks could be due to bit error rate (BER), link failure or handoffs. If standard TCP is applied on such wireless networks without any modification, it may lead to performance degradation. To address these problems, many solutions have been proposed for TCP enhancements over wireless networks. We have analyzed the performance of New Reno, selective acknowledgements (SACK), explicit congestion notification (ECN) and Westwood by simulation. The performance was measured on the basis of average throughput, packet loss ratio and average end-to-end delay in three different situations: mobility (variable speed); link loss; both mobility and link loss. Results show that New Reno is more stable and consistent in the absence of congestion, otherwise ECN performs best.","PeriodicalId":337263,"journal":{"name":"2004 International Networking and Communication Conference","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122823357","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 ubiquity of the Internet and the easy perpetration of attacks will lead to more hostile traffic. With the advent of high-speed Internet connections, organizations today find it difficult to detect intrusions. So multi sensor intrusion detection systems are inevitable. The optimum distribution of traffic to the sensors is a challenging task. We present a mechanism to split traffic to different intrusion detection sensors (e.g., SNORT based sensors) to make the task manageable. This splitting of traffic to each sensor is managed by policies enforced on the splitter by the management console. The system is adaptive in the sense that it can adjust the splitting policies for keeping load disparity among sensors reduced. This mechanism of policy-reloading also take into account the similarity between all possible pairs of policies and tries to minimize the packet duplication rate during the operation of the system. Our mechanism is based on the observation that minimizing the percentage of traffic being duplicated can enhance system performance. We also discuss the effects of the reloading of splitting policies on packet duplication rate and on the load on the sensors.","PeriodicalId":337263,"journal":{"name":"2004 International Networking and Communication Conference","volume":"46 15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123930341","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}
