Cooperation by relaying data of other wireless nodes is crucial in (next-generation) wireless networks as it can greatly attribute to ensuring connectivity, reliability, performance, etc. As power saving relies on sleep mode, turning off the communication subsystem for predetermined amounts of time, it can greatly affect data relaying as a cooperator node may not be awake when there is data to relay. Rather than modelling one of the wireless protocols in detail, we construct a high-level queuing model capturing the two essential characteristics of cooperation and energy efficiency: relaying and sleep mode. The used analytical approach allows for accurate performance evaluation and enables us to investigate the trade-off between data relaying and energy efficiency.","PeriodicalId":271890,"journal":{"name":"2013 Conference on Future Internet Communications (CFIC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129245568","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}

This paper focuses on the problem of some nodes trying to impair the communication of a VDTN. In the paper we study the case of nodes that delay the forwarding of messages that is a particularly difficult to detect form of misbehavior. We study the impact of this form of misbehavior on eight VDTN routing protocols using a large set of simulations and two scenarios. The results show that depending on the type of misbehavior, message replication and intelligent selection of the next hop can help routing protocols to be resilient to node misbehavior.","PeriodicalId":271890,"journal":{"name":"2013 Conference on Future Internet Communications (CFIC)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114797630","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}

Though CCN is capable of multi-path communications by design, no work has been done to characterise multi-path content transfers in CCN with an analytical model. In this work, we have developed an analytical model to evaluate the performance of multi-path content transfers in CCN. The performance of this model is then compared against a packet level CCN simulator built in OPNET. Round trip times, throughput and download times are obtained for both multi-path and single path to make comparisons of performances. The comparisons indicate that the results obtained from the simulator are in agreement with the results of the analytical model.","PeriodicalId":271890,"journal":{"name":"2013 Conference on Future Internet Communications (CFIC)","volume":"404 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124313161","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}

Such a quite general queueing system suits for modeling, e.g., modern wireless communication networks.

This mechanism is vulnerable to brute-force attacks that can be used for distributed denial-of-service (DDoS) attacks and unsolicited messages (spam). In this paper we analytically calculate the probability of brute-force attacks and determine the time required by the attacker to launch a successful attack. We find that using scenarios reported by other researchers this type of attacks is achievable in few seconds, which is unacceptable. The paper proposes a solution to mitigate the brute-force attacks by significantly increasing the time before a successful attack. Consequently, it is possible to change link identifiers before the attacker can adapt to the changes. We evaluate the proposed solution in terms of network security and scalability.","PeriodicalId":271890,"journal":{"name":"2013 Conference on Future Internet Communications (CFIC)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123105724","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}

One of these challenges is that of accurate timer synchronization of the data collecting nodes, so as to ensure that there is a consistent view of the data retrieval times. In this paper we discuss a novel approach for an one-way time synchronization protocol that relies on the use of cross-layer timing information to estimate the accumulated delay since a block of data is created until it is received at the sink node. The accumulated delay is computed using the Application, Network and Link layers in the 802.11b technology. At each node which belongs to a route a Protocol Data Unit (PDU) inserted between the User Datagram Protocol (UDP) header and the application payload, is manipulated in order to accumulate the calculated delay. This delay is iteratively incremented along the path until it is finally provided to the receiving application. The developed protocol provides a fairly accurate estimation of the delay a message experiences through a WSN, adding no extra packets and little data overhead. Our experimental evaluation showed that it is able to determine the end-to-end delay of most messages with an error inferior to 700μs in one hop scenarios and to 1500μs in two hops scenarios.","PeriodicalId":271890,"journal":{"name":"2013 Conference on Future Internet Communications (CFIC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125185205","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}

This paper proposes to use greedy routing also in overlay networks by positioning overlay nodes into a multi-dimensional Euclidean space. Greedy routing can only be applied when a routing decision makes progress towards the final destination. Our proposed overlay network is built such that there will be always progress at each forwarding node. This is achieved by constructing at each node a so-called nearest neighbor convex set (NNCS). NNCSs can be used for various applications such as multicast routing, service discovery and Quality-of-Service routing. NNCS has been compared with Pastry, another topology-aware overlay network. NNCS has superior relative path stretches indicating the optimality of a path.","PeriodicalId":271890,"journal":{"name":"2013 Conference on Future Internet Communications (CFIC)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134493673","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}
