Due to destroyed infrastructure, Mobile Ad hoc Networks (MANETs) might be the only option for communication in such scenarios. However, such MANETs get partitioned frequently due to node movements resulting in intermittent connectivity. Delay Tolerant Networks (DTNs) are suitable to handle this. With the help of DTNs, rescue teams can exchange information including multicast messages to all team members. The major challenge is to ensure that all team members or intended recipients receive a DTN multicast message. Several problems need to be solved for that, among which we consider the identification of the recipients and the limited resources of the nodes. In this paper, we present an extension of our protocol that enhances our existing buffer management approach and combines it with a configurable delivery ratio which should be reached. This configurable ratio is used to prioritize multicast messages and thus enhance their delivery probability. Besides that, we added a mechanism to selectively deliver the messages based on group membership intervals. Our simulation results show that this approach can ensure a higher delivery ratio for multicast messages in disaster scenarios.","PeriodicalId":248916,"journal":{"name":"2015 7th International Workshop on Reliable Networks Design and Modeling (RNDM)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114283258","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}

But with the deepening research on Optical NoCs (ONoCs), the superiority of ONoCs is becoming increasingly obvious. As the most efficient on-chip communication way, ONoC also presents some fault situations due to manufacturing defects. To ensure the operating reliability of ONoCs, a novel adaptive reliable routing algorithm NRFTA (Node Reuse Fault Tolerant Algorithm) is designed by us. After extending the internal structure of Optical Routers (ORs), we utilize NRFTA to tolerate arbitrary number/distribution of the faults from microring resonators. NRFTA can find the restore path within each disabled OR, i.e., fault-node reuse, instead of rerouting packets along the restore path detouring around disabled ORs. Thus, the best macroscopic path along with the least ORs is guaranteed by NRFTA. Simulation results demonstrate that NRFTA performs better than benchmarks, in terms of transmission latency and signal-to-noise ratio.","PeriodicalId":248916,"journal":{"name":"2015 7th International Workshop on Reliable Networks Design and Modeling (RNDM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129647789","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 a majority of simulation results, the physical layer is often affected by an apparent lack of realism. Therefore, vehicular channel model has become a critical issue in the field of intelligent transport systems (ITS). To overcome the lack of realism problem, a more robust channel model is needed to reflect the reality. This paper provides an open access, predefined channel coefficients library. The library is based on 2×2 and 4×4 Multiple - Input - Multiple - Output (MIMO) systems in V2V communications, using a spatial channel model extended SCME which will help to reduce the overall simulation time. In addition, it provides a more realistic channel model for V2V communications; considering: over ranges of speeds, distances, multipath signals, sub-path signals, different angle of arrivals, different angle departures, no line of sight and line of sight. An intensive evaluation process has taken place to validate the library and acceptance results are produced. Having an open access predefined library, enables the researcher at relevant communities to test and evaluate several complicated vehicular communications scenarios in a wider manners with less time and efforts.","PeriodicalId":248916,"journal":{"name":"2015 7th International Workshop on Reliable Networks Design and Modeling (RNDM)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127500307","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}

First, we introduce a general framework for extending restoration strategies developed for total link failures in a way enabling handling partial link failures as well. In particular, our framework combines a known rerouting method for total link failures (the so called Restricted Restoration - RR) and a recently developed restoration method for partial failures (called Flow Thinning - FT). In this way we achieve two goals: we define a unified approach to deal with both kinds of failures, and improve efficiency of FT. We study in detail such an extended version of RR (that can also be regarded as an extension of the MPLS Fast Reroute method) capable of managing links with variable capacities, (variable link capacities can be regarded as partial link failures). A general mathematical model for the framework, and a specific model for RR are presented together with numerical results. The second purpose is related to completeness of partial failures scenarios. In practice, partial failure scenarios correspond to partial losses in transmission capacity, occurring for example in wireless networks using microwave radio or free space optical transmission technology. As such failures are mainly caused by weather conditions, there arises a problem of how to translate weather conditions to link failures (this is necessary to ensure network robustness to weather conditions). We present a study on the way that different weather factors impact the transmission link capacity and how these effects can be measured.","PeriodicalId":248916,"journal":{"name":"2015 7th International Workshop on Reliable Networks Design and Modeling (RNDM)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123354161","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}

However, an effective distribution of Roadside Units (RSUs) is considered to be one of the main challenges for deployment of roadside networks, especially due to the wide range of influencing factors that can affect the distribution process. Some of these influencing factors are traffic, topological and infrastructure characteristics of the roads and technology used. This paper introduces the Cumulative Weight based Method (CWM) as a solution to the placement problem in the urban, rural and mountainous areas. The CWM gets the weight of each Site of Interest (SoI) and adds the weights of the surrounding neighbors to its weight and considers the highest weight first in the distribution process. The CWM during the current state of development considers working with the radius of RSUs and connectivity requirements. Moreover, it will be influenced by many other factors. The tests conducted on selected areas in Rostock (Germany) and Spiringen (Switzerland) showed: (1) a reduction in the number of SoIs compared to the original number acquired during the scanning process; (2) only the highest priority SoIs are chosen as the best location for an RSU placement; (3) 3D space calculations for distance on mountainous areas gave a different, more accurate results than 2D space calculations.","PeriodicalId":248916,"journal":{"name":"2015 7th International Workshop on Reliable Networks Design and Modeling (RNDM)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117270912","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}
