These include its ability to prevent the hidden-terminal problem, and the guarantee of strict quality-of-service (QoS) for providing real-time applications. However, time slot assignments to vehicles could suffer from an unstable problem, called merging collisions. This problem is due mainly to the changing network topology of a VANET, which can be characterized by vehicles joining into or leaving from a cluster of vehicles. In this paper, we focus on the problem of unstable time slot assignments facing several existing TDMA approaches, and a scheme is proposed to effectively alleviate this problem.","PeriodicalId":301015,"journal":{"name":"International Symposium on Wireless and pervasive Computing (ISWPC)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123993434","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}

Any node that accepts information from the other nodes will start transmitting that information if it satisfies the required conditions of the protocol that is in use. In a t-latency bounded information propagation problem, we need to find a minimal set of nodes that will start to transmit information initially so that the whole set of nodes can start transmitting within the given time period, t. In this paper we provide an approximation scheme for a t-latency bounded information propagation problem in heterogeneous wireless networks and we are the first to propose such scheme. We also derive the approximation ratio of our scheme and show that the ratio is bounded by a factor ε which is constant for a particular network.","PeriodicalId":301015,"journal":{"name":"International Symposium on Wireless and pervasive Computing (ISWPC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121832316","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 there are limited number of channels in IEEE 802.11 a/b/g/p standards, so efficient mechanisms are required to allocate the same for new incoming requests from the users. Keeping in view of the same, we propose a modified TDMA based virtual back off algorithm for VANETs. Vehicles are assumed to be arrived using Poisson distribution and served as exponential. By varying the distance from RSUs, we have provided the analysis of end-to end delay for varying speed of vehicles.","PeriodicalId":301015,"journal":{"name":"International Symposium on Wireless and pervasive Computing (ISWPC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122760877","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}

Different from other participatory sensing application challenges who consider user privacy and data trustworthiness, we consider network trustworthiness problem namely Sybil attacks in participatory sensing. Sybil attacks focus on creating multiple online user identities called Sybil identities and try to achieve malicious results through these identities. In this paper, we proposed a Cloud based Trust Management Scheme (CbTMS) framework for detecting Sybil attacks in participatory sensing network. Our CbTMS was proposed for performing Sybil attack characteristic check and trustworthiness management system to verify coverage nodes in the participatory sensing. To verify the proposed framework, we are currently developing the proposed scheme on OMNeT++ network simulator in multiple scenarios to achieve Sybil identities detection in our simulation environment.","PeriodicalId":301015,"journal":{"name":"International Symposium on Wireless and pervasive Computing (ISWPC)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126674977","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}

When a plausible statistical modeling of primary user signal is given, the amount of interference to primary user signal can be estimated and used to produce the optimal spectrum sensing and data transmission time. However, previous works on this area have some flaws in the modeling of interference to primary user signal. In this study we apply more accurate modeling of primary user signal to the spectrum sensing framework. Our method uses Chapman-Kolmogorov equation to model the behavior of primary user signal in a certain instant and derive the optimal spectrum sensing framework. Numerical results show that the proposed method results in higher throughput of secondary users than previous methods.","PeriodicalId":301015,"journal":{"name":"International Symposium on Wireless and pervasive Computing (ISWPC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130262007","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}

It can be systematically applied for random access protocols under different feedback information which includes binary, ternary and feedback of the number of accessing packets.

This paper aims to investigate which one strategy in these three strategies is the best effective to improve the system performance. Based on simulation results, when the information about number of accessing packets is available, significant improvement in mean access delay can be achieved.
