This makes it very difficult for security administrators to analyze and detect network attacks. Our solution for this problem is to make the alerts machine understandable. We propose a novel way to convert the raw alerts into machine understandable uniform streams, correlate the streams, and extract the attack scenario knowledge. The modified case grammar principal-subordinate consequence tagging case grammar and the 2-atom alert semantic network are used to generate the attack scenario classes. Alert mutual information is also applied to calculate the alert semantic context window size. Based on the alert context, the attack scenario instances are extracted and the attack scenario descriptions are forwarded to the security administrator.","PeriodicalId":366183,"journal":{"name":"29th Annual IEEE International Conference on Local Computer Networks","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131282093","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}

Maximizing the coverage area while maintaining a lower cost of deployment has always been a challenge, especially when the monitoring region is unknown and possibly hazardous. In this paper, we present a method to deterministically estimate the exact amount of coverage holes under random deployment using Voronoi diagrams and use the static nodes to collaborate and estimate the number of additional mobile nodes needed to be deployed and relocated to optimal positions to maximize coverage. We follow a two-step deployment process in a mixed sensor network and we argue by simulation and analysis that our collaborative coverage enhancing algorithm (COVEN) can achieve a tradeoff between the cost of deployment and percentage of area covered.","PeriodicalId":366183,"journal":{"name":"29th Annual IEEE International Conference on Local Computer Networks","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132722935","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}

Apart from its natural role as a unifier, IP also comprises the main drive for network evolution towards all-IP network infrastructures. In this regard, we exploit IP as an enabler for the evolution of the UMTS packet-switched core network, eliminating its duality at user and transport level. We focus on mobility management in the core network, which is handled by pure IP mechanisms, and on the support of fast handoff across UMTS access networks by means of a hybrid Fast and Hierarchical Mobile IPv6 (F/HMIPv6) proposal. Emphasis is also put on identifying the proper points of interaction between the F/HMIPv6 operation and the UMTS-specific serving radio network subsystem (SRNS) relocation procedure in order to provide a seamless handoff service to the user while not compromising the network's performance and scalability.","PeriodicalId":366183,"journal":{"name":"29th Annual IEEE International Conference on Local Computer Networks","volume":"155 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124350080","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 contrast to this, there are no specific mobility or traffic models for MANETs. We present a realistic approach to realize mobility in disaster areas based on tactical issues of civil protection. The new model is analyzed and compared to Gauss-Markov and random waypoint mobility models. Furthermore, we present first simulation results. The mobility model analysis as well as the simulation are based on two real disasters that occurred in Germany in 1999 and 2001. We show that disaster area scenarios have specific characteristics. Thus, they should be considered in MANET performance evaluation.","PeriodicalId":366183,"journal":{"name":"29th Annual IEEE International Conference on Local Computer Networks","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114697481","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}

Nandy","doi":"10.1109/LCN.2004.47","DOIUrl":"https://doi.org/10.1109/LCN.2004.47","url":null,"abstract":"An ad hoc network is composed of mobile nodes without any infrastructure. Mobile nodes self organize themselves to form a network over radio links. The trend of applications of mobile ad hoc networks requires increased group oriented services. Hence multicast support is critical for ad hoc networks. As the number of participating nodes increase, scalability becomes an important issue. The on demand multicast routing protocol (ODMRP) provides high packet delivery ratio in presence of high mobility. But ODMRP suffers from higher control overhead as the network size and the number of source nodes increase. In this paper we present an efficient hybrid multicast routing protocol suitable for high mobility applications which addresses the scalability issue of the ODMRP protocol. This protocol separates out the data forwarding path from the join-query forwarding path. We incorporate a low overhead local clustering technique to classify all nodes into core and normal categories. When multicast routes to destination nodes are unavailable, join-query messages are sent to all nodes in the network and data packets are forwarded by the core nodes to the destination nodes using differential destination multicast. Through simulations we show that this protocol reduces control overhead and increases packet delivery ratio by 20-50% for different network scenarios.","PeriodicalId":366183,"journal":{"name":"29th Annual IEEE International Conference on Local Computer Networks","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117171009","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 first one, we call the \"active approach\", allows us to define protocols (or services) adapted to flow contents (in particular their semantics) but does not permit us to set priorities to flows. The second one uses QoS provided by the IP network layer (under active networks). The weakness of this latter approach is then identified: while it simplifies the implementation of QoS in active networks, the obtained QoS is almost as flexible as the service offered by IP layer. We propose a new approach where QoS is managed at \"active network\" layer rather than at IP layer. This new approach is far more flexible and allows us to provide QoS mechanisms not limited by those at the IP layer. We show that our solution offers QoS with a better granularity: packet-grained rather than flow-grained We have performed many experiments that validate this flexible approach of QoS at the active network layer in particular on the high-speed active node Tamanoir.","PeriodicalId":366183,"journal":{"name":"29th Annual IEEE International Conference on Local Computer Networks","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127589924","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 multi-fractal nature of traffic volume in general is well known to have a significant influence on queueing behavior in short time scales. In our previous study, we showed that the retransmission time out (RTO) mechanism plays an important role in the multi-fractal nature of TCP traffic. In this paper, we investigate how to control the multifractal nature of TCP traffic in a real network. Here we focus on the random early detection (RED) mechanism in order to reduce the occurrence of RTO. We evaluate the RED mechanism from the viewpoint of its multi-fractal nature and show that the RED mechanism improves not only throughput and delay performance, but also the multi-fractal nature of TCP traffic.","PeriodicalId":366183,"journal":{"name":"29th Annual IEEE International Conference on Local Computer Networks","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114480568","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}
