The wireless channel is vulnerable to malicious nodes that can eavesdrop data exchanges. Moreover, all nodes in an opportunistic network can act as routers and thus, gain access to sensitive information while forwarding data. Node anonymity and data protection can be achieved using encryption. However, cryptography-based mechanisms are complex to handle and computationally expensive for the participating (mobile) nodes. We propose SimBet-BF, a privacy-preserving routing algorithm for opportunistic networks. The proposed algorithm builds atop the SimBet algorithm and uses Bloom filters so as to represent routing as well as other sensitive information included in data packets. SimBet-BF provides anonymous communication and avoids expensive cryptographic operations, while the functionality of the SimBet algorithm is not significantly affected. In fact, we show that the required security level can be achieved with a negligible routing performance trade-off.","PeriodicalId":221796,"journal":{"name":"2015 IEEE 16th International Symposium on A World of Wireless, Mobile and Multimedia Networks (WoWMoM)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131934640","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}

Since video is very bandwidth consuming, its distribution costs are becoming too high to scale with network investments that are required to support the increasing bandwidth demand. Content providers and operators are searching for solutions to reduce this video traffic load, without degrading their customers' perceived Quality of Experience (QoE). This paper proposes a method that can programmatically optimize video content for desired QoE according to perceptual video quality and device display properties, while achieving bandwidth and storage savings for content providers, operators, and end users. The preliminary results obtained with Samsung Galaxy S3 phone show that up to 60% savings can be achieved by optimizing movies without compromising the perceptible video quality, and up to 70% for perceptible, but not annoying video quality difference. Tailoring video optimization to individual user perception can provide seamless QoE delivery across all users, with a low overhead (i.e., 10%) required to achieve this goal. Finally, two applications of video optimization: QoE-aware delivery and storage, are proposed and examined.","PeriodicalId":221796,"journal":{"name":"2015 IEEE 16th International Symposium on A World of Wireless, Mobile and Multimedia Networks (WoWMoM)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123644120","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}

Network providers are looking for techniques that selectively offload the mobile data traffic onto WiFi (IEEE 802.11) networks to balance the load and improve network performance. Several architectures based on Proxy Mobile IPv6 (PMIPv6) have been proposed to support seamless data offloading. The demerits of PMIPv6 include lack of flow mobility and single point of failure. There exist architectures that extend PMIPv6 to support flow mobility, but still face the problem of overhead at the gateway and single point of failure. In this paper, we propose Seamless Internetwork Flow Mobility (SIFM), a new architecture that overcomes these drawbacks and provides seamless data offload supporting flow mobility. Both the PMIPv6 and the SIFM architectures have been implemented and evaluated incorporating salient LTE and WiFi network features in the ns-3 simulator. The performance studies validate that seamless mobility can be achieved for clients in both of these architectures. The results show that for the best possible (scenario dependent) offload value, the SIFM architecture shows an improvement of 13.86%, 29.05% and 11.33% whereas the PMIPv6 architecture shows an improvement of 7.96%, 19.52% and 7.83% in terms of delay, packet loss and throughput respectively compared to no offload scenario in each architecture. Further, we also show that the support for flow mobility in the SIFM architecture provides the flexibility to move selective flows to another network. This helps in achieving better performance gain compared to moving all the flows of the user as done in the PMIPv6 architecture.","PeriodicalId":221796,"journal":{"name":"2015 IEEE 16th International Symposium on A World of Wireless, Mobile and Multimedia Networks (WoWMoM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125791154","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}
