Information dissemination is a challenging problem in MOSNs, due to uncertainty and intermittent connectivity. In this paper, we propose a distributed social tie strength calculation mechanism to identify the relationship between each set of pairwise mobile nodes. Following arguments originally proposed by Mark Granovetter's seminal 1973 paper, The Strength of Weak Ties, the majority of the novel information dissemination is generated by weak ties. We first evaluate the strength of weak ties in MIT reality mining data. Then, a social-tie-based information dissemination protocol is presented, which is a token-based information dissemination scheme, including two phases: weak tie-driven forwarding and strong tie-driven forwarding. In the weak tie-driven forwarding phase, the susceptible nodes with more weak ties will receive more tokens for future forwarding. The number of forwarding tokens is related to the number of weak ties of two encountered nodes. After a while, the information will have been spread to multiple communities. Our scheme switches to a strong tie driven forwarding phase, in which the influential nodes are more important. The number of forwarding tokens is proportional to the number of strong ties of two encountered nodes. Extensive simulations are conducted in comparison to several approaches in real world mobile traces.","PeriodicalId":158378,"journal":{"name":"2013 IEEE 14th International Symposium on \"A World of Wireless, Mobile and Multimedia Networks\" (WoWMoM)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127729604","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}

As a consequence, inter-cell interference is becoming the most serious obstacle towards spectral efficiency. Therefore, considering that radio resources are limited and expensive, new techniques are required for efficient radio resource allocation in next generation cellular networks. In this paper, we propose a pure frequency reuse 1 scheme based on base station scheduling rather than the commonly adopted user scheduling. In particular, we formulate a base station scheduling problem to determine which base stations can be scheduled to simultaneously transmit, without causing excessive interference to any user of any of the scheduled base stations. We show that finding the optimal base station scheduling is NP-hard, and formulate the BASICS (BAse Station Inter-Cell Scheduling) algorithm, a novel heuristic to approximate the optimal solution at low complexity cost. The proposed algorithm is in line with the ABSF (almost blank sub-frame) technique recently standardized at the 3GPP. By means of numerical and packet-level simulations, we prove the effectiveness and superiority of BASICS as compared to the state of the art of inter-cell interference mitigation schemes.","PeriodicalId":158378,"journal":{"name":"2013 IEEE 14th International Symposium on \"A World of Wireless, Mobile and Multimedia Networks\" (WoWMoM)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132314465","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}

A new method, called ORCA (On-demand Routing with Coordinates Awareness) is introduced for the dissemination of route requests in MANETs. The selection of relaying nodes at each node in ORCA is done by computing the shortest Euclidean Distance from all neighbors of the node to four polar points located in the transmission range of the node. We prove that ORCA guarantees the coverage of all nodes in a connected MANET, and that the number of relays for each node is at most six. ORCA is compared with representative routing protocols, namely AODV, OLSR, LAR, and THP. The simulation results in networks of 200 and 250 nodes show that ORCA incurs the smallest routing load while attaining average delays and packet delivery ratios that are comparable to or better than those obtained with the other four routing protocols.","PeriodicalId":158378,"journal":{"name":"2013 IEEE 14th International Symposium on \"A World of Wireless, Mobile and Multimedia Networks\" (WoWMoM)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131601951","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}

Data aggregation, which reduces the data redundancy so as to mitigate energy consumption, is one of desirable solutions. One common feature of geographically close-by data known as spatial correlation, has been utilized for eliminating redundant information. To reduce redundancy and enhance eventual performance, we explore the possibility of combining sensing data with similar characteristics without considering spatial information.We define this relationship of data as characteristic correlation and propose an automatic procedure to discover characteristic correlation between sensor nodes (SNs) with limited overheads. Furthermore, we introduce a novel characteristic correlation based data aggregation approach that allows any SN to compress unlimited number of packets into virtual packets up to a constant number. With experimental and simulation results, our proposed approach is illustrated as an effective data aggregation method in term of data accuracy.","PeriodicalId":158378,"journal":{"name":"2013 IEEE 14th International Symposium on \"A World of Wireless, Mobile and Multimedia Networks\" (WoWMoM)","volume":"420 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114949226","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}

Extensions have been done with respect to two axes: Our proposed Malleability Resilient Concealed Data Aggregation (MR-CDA) combines recently presented homomorphic MACs with additively homomorphic encryption schemes and thus helps detecting outsider attacks which maliciously add resp. inject encrypted data to an aggregated encrypted data format. In the visionary part of this work with the malleability resilient premium concealed data aggregation (MR-P-CDA) we investigate what cryptographic primitives are in principle available to provide the most flexible form of encrypted in-network processing. Whereas the MR-CDA is in particular optimized with respect to its computational performance, the MR-P-CDA intentionally is not taking into account performance issues. Instead its focus is on the provisioning of an overall system security without any functional restrictions.","PeriodicalId":158378,"journal":{"name":"2013 IEEE 14th International Symposium on \"A World of Wireless, Mobile and Multimedia Networks\" (WoWMoM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130893884","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}
