However, their capacity is limited due to the nature of the radio channel, which must be shared by the nodes forwarding the traffic from and to the gateway. Therefore, estimating the capacity of WMNs is an important question. The capacity analysis proposed for ad hoc networks can not be directly applied to WMN due to some fundamental differences, e.g. a different traffic pattern and node density. The main contribution of this work is the application of collision domains concept to the 802.16 based WMNs. We consider a simple chain topology but the method can be extended to any arbitrary topology and the real world impairments (interference, fading, etc.) can be easily incorporated in the analysis. The presented results may have important implications for 802.16 mesh networks planning.","PeriodicalId":115389,"journal":{"name":"2009 Second International Conference on Advances in Mesh Networks","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128837373","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 previous works on these structures verify that N2R are better than other degree three regular topologies such as Double Rings or Honeycomb in terms of path distances. The cost of this good performance is a more complex and non-planar interconnection configuration; It is complex to find analytical models to be used, for example for describing topological parameters. This paper proposes and verifies the possibility of approximating real N2R graphs to optimal and ideal graphs, which are much easier to model, obtaining fairly accurate results. A main result of the paper is a simple formula for approximating average distance and diameter given the number of nodes in a N2R graph.","PeriodicalId":115389,"journal":{"name":"2009 Second International Conference on Advances in Mesh Networks","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122653409","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 scheme exploits the broadcast nature of wireless transmissions at special routers with added monitoring functionalities. These routers passively listen to the transmissions in the neighborhood and compare the forwarding behavior against pre-specified thresholds. If forwarded traffic exceeds the threshold, as a result of a malfunction, e.g., Denial-of-service (DoS) attack or node failure, these routers try to isolate the node causing the problem by routing the traffic around it. The performance evaluation of our scheme shows considerable improvement in data delivery rates over standard routing schemes.","PeriodicalId":115389,"journal":{"name":"2009 Second International Conference on Advances in Mesh Networks","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126958100","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}

Thegray zone effect can happen when broadcasting controlpackets with lower rate while transmitting the data packetswith such higher rate or the same PHY data rate. In thiscase, nodes are able to find valid routes but some datapackets may not reach the destination, which causes thehigh packet loss rate. Most research efforts so far haveattempted to modify the routing protocol to take the grayzone effect into consideration. This method, however, couldhave a detrimental performance owning to its high computationalcomplexity. In this paper, by adjusting the suitablebroadcast rate and data transmission rate, we can obtainhigher throughput than the original way. By simulations,we show that our simple approach can improve throughputsignificantly.","PeriodicalId":115389,"journal":{"name":"2009 Second International Conference on Advances in Mesh Networks","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127464676","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 order to scale up IWMNs, it is an interesting approach to split routing capabilities into a layered routing architecture, in which the base layer is defined by a neighborhood discovery protocol employed to detect the presence and status of neighbor nodes. In such a context, this paper presents SNDP, a scalable neighborhood discovery protocol that has been specifically designed for IWMNs. SNDP adopts a hybrid, collaborative signaling strategy, in which different types of nodes adopt distinct signaling approaches that work together to manage neighborhood concerns. By reducing signaling load, power consumption and neighborhood discovery time, SNDP has the potential to become a better choice than the current work-in progress proposed by the IETF MANET working group.","PeriodicalId":115389,"journal":{"name":"2009 Second International Conference on Advances in Mesh Networks","volume":"29 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120912302","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 the DoS attack, when extortionate high-load flows flood to individual Mesh Routers (MR), they can no longer provide normal services to innocent flows. An active cache based defense solution can detect the existence of attacking flows based on thefrequency of incoming packets and eliminate the attacking flows by discarding packets by a Drop Probability(DP). As shown in our simulation study, the selection and variance of DP have a significant impact on the performance of the defense solution to both attacking flows and innocent flows. In this paper, a series of DP selection and variance methods are employed in our simulation studies. From them, we can optimize the DP methods and correspondingparameter setting of the solution against Dos attack by the analysis on the simulation results.","PeriodicalId":115389,"journal":{"name":"2009 Second International Conference on Advances in Mesh Networks","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115251397","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}
