IEEE802.11e (EDCA) standard is concerned to support QoS in wireless adhoc networks. Thereby, EDCA differentiates and classifies the packets in Access Categories depending on their priorities. However, it cannot guarantee strict QoS required by real-time and multimedia services without proper network control mechanisms. And also, the unfairness of bandwidth sharing ,because of the hidden and exposed terminals problems, leads to degrade the guarantee services. Our proposition (FQ-EDCA) is to enhance the QoS of EDCA by implementing a Fair Queuing scheduling technique and improving the architecture of EDCA scheme. FQ-EDCA is proved and analyzed by experimental simulations for many topologies like (star, chain, tree, ...). Thus, the bandwidth is distributed fairly between all the source nodes. As a consequence, these nodes can access the channel fairly to transmit their flows with respect to EDCA specifications of Access Categories (AC) priorities. And also, the delay of flows of the same priorities is minimized and nearly fixed for all the source nodes. This leads to minimize the Jitter also. Therefore, the services guarantees of QoS is enhanced.","PeriodicalId":299215,"journal":{"name":"2009 Eighth International Conference on Networks","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124711028","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 consequence, a scheme for the distribution of data processing that minimizes local peaks in energy consumption isneeded.

In this paper, we propose a simple routing protocol that constructs routes depending on a remaining battery capacity. Then, we explore a new type of sensor network with forwarder nodes and a data aggregation scheme. The forwarder node is a special node that has a large size of battery and supports the route construction to the sink node from sensor nodes. Finally, we evaluate the advantage of the data aggregation scheme for this sensor network. In numerical results, we show that our protocol can extend the lifetime of the sensor networks and improve the event delivery ratio at the sink node.","PeriodicalId":299215,"journal":{"name":"2009 Eighth International Conference on Networks","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129968526","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, they have usually considered occasional mobility, in which a few number of nodes may start moving at very low speeds and then remained immobile for a long period of time. In this paper, we propose a modified version of LMAC as Mobile-LMAC (M-LMAC) to improve its performance in the scenarios include continuous mobility. The protocol is compared to SMAC and LMAC by simulation. The results show that the proposed M-LMAC protocol has much better performance in terms of packet delivery ratio, network life time and end-to-end delay in presence of mobile nodes.","PeriodicalId":299215,"journal":{"name":"2009 Eighth International Conference on Networks","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130922628","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 proposed method delivers high quality session-based services compliant with the available capacity over an NGN network based IP/MPLS transport infrastructure.

Security, routing protocols, and connectivity are major issues with mobile ad hoc networks, and seeking a solution to these and other problems is of great interest within the research community.All of these problems are affected by the number of neighbors that a given node has at a given time. In this paper, we examine the number of neighbors that a node has at an arbitrary moment during simulation time. We find that the interested number is not stuck with the node distribution or speed stable state but rather it fluctuates until converging after a period of time. Based on the results obtained from simulations, we have built a statistical model to grab a view of the number of neighbors each node has. Additionally, we have addressed some problems that are closely related to the average number of neighbors.","PeriodicalId":299215,"journal":{"name":"2009 Eighth International Conference on Networks","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126350768","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}

Of those widely deployed are content adaptation mechanisms whereby the quality level of the content is adapted dynamically to mitigate overload conditions. Serving degraded content reduces strain on resources and enables them to cater for a larger set of clients. To that end, this paper studies adversarial exploits of dynamic content adaptation mechanisms to a new instantiation of Reduction of Quality (RoQ) attacks. The RoQ attack pattern is orchestrated to cause different forms of damage such as longer response time for legitimate clients, degraded content being served and underutilization of resources. We assess the impact of RoQ attacks via the potency metric which reflects the tradeoffs between the damage inflicted and the cost in mounting the attack. We validate our results through numerical analysis as well as real Internet experiments.","PeriodicalId":299215,"journal":{"name":"2009 Eighth International Conference on Networks","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114227236","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}
