Multi-hop Cellular Networks using Mobile Relays (MCN-MR) are characterized by a decentralized and cooperative operation that provides new networking opportunities but also significant management challenges. In this context, this work investigates the use of opportunistic store-carry and forward schemes in MCN-MR networks to increase energy efficiency in the provision of delay tolerant services. In particular, the paper identifies for a two-hop MCN-MR scenario the optimum mobile relay location and the location from which the relay should start forwarding the information to the cellular base station in order to minimize the overall energy consumption. Taking this optimum configuration as a reference benchmark, the paper proposes then a scheme that relaxes the requirement to operate under the identified optimum configuration, and exploits context information provided by the cellular infrastructure. The proposed scheme is compared against other forwarding approaches, and the obtained results demonstrate the capacity of opportunistic forwarding in MCN-MR to reduce energy consumption for delay tolerant services.","PeriodicalId":166569,"journal":{"name":"HP-MOSys '13","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127998276","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}

Most social-based routing protocols use social information extracted from real-world encounter networks to select an appropriate message relay. A protocol based on encounter history, however, takes time to build up a knowledge database from which to take routing decisions. An opportunistic routing protocol which extracts social information from multiple social networks, can be an alternative approach to avoid suboptimal paths due to partial information on encounters. While contact information changes constantly and it takes time to identify strong social ties, online social network ties remain rather stable and can be used to augment available partial contact information. In this paper, we propose a novel opportunistic routing approach, called ML-SOR (Multi-layer Social Network based Routing), which extracts social network information from multiple social contexts. To select an effective forwarding node, ML-SOR measures the forwarding capability of a node when compared to an encountered node in terms of node centrality, tie strength and link prediction. These metrics are computed by ML-SOR on different social network layers. Trace driven simulations show that ML-SOR, when compared to other schemes, is able to deliver messages with high probability while keeping overhead ratio very small.","PeriodicalId":166569,"journal":{"name":"HP-MOSys '13","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133928645","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}

Opportunistic Routing (OR) is a broadcast based technique widely used in Delay Tolerant Networks (DTNs) that uses the relay node negotiation and link attributes to forward the data in the network. Multiple retransmissions in opportunistic routing increase the communication overhead in the network. Hence, node scheduling and network coding techniques are used to reduce the rate of re-transmissions in the network. In this article, we present a novel approach using Agent-based Multicast Opportunistic Routing Protocol (Agent-based MORP) to reduce the load of the source node by re-establishing the links with multicast member nodes using opportunistic link attributes of the network. The proposed protocol elects the maximum trusted relay node as the agent node to transfer the long-awaited data packets towards the destination. Agent-based MORP uses the stateless approach, where the forwarding nodes are divided into probable relay regions, and the routing paths are established on demand. The proposed protocol limits the number of re-transmissions and saves the energy in the network. Simulation results indicate that the proposed Agent-based MORP reduces the control overhead and improves the performance of opportunistic routing in wireless networks.","PeriodicalId":166569,"journal":{"name":"HP-MOSys '13","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121493370","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}

Therefore, it should be carefully studied in order to allow the creation of appropriate traffic models to be used for simulations. First, to demonstrate the traffic shaping effect, we present statistical analyses on real-time measurements of diverse traffic sources (voice and video over IP) in a 3G network. By comparing the statistical distributions of the packet inter-arrival times for both the forward and backward direction, we can demonstrate directly the end-to-end traffic shaping effect introduced by the IP core network. Hence, we argue that distributed QoS management approach is needed. Additionally, we give the mean, variance, mean standard deviation, skewness, and kurtosis of the inter-arrival times, which can be used as input for simulation models. The accurate validation of the probability distributions is ensured by the Wolfram Mathematica and Crystal Ball statistical tools. Second, for the same set of measurements, we propose and defend with evaluations the use of the gamma distribution as best fitting function to traffic dynamics. Our proposal is applicable for traffic environments found in delay-tolerant networks, opportunistic networks, Internet of Things, sensor networks etc.","PeriodicalId":166569,"journal":{"name":"HP-MOSys '13","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116850684","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}
