As this competition becomes intense, the distribution of resources may become extremely haphazard, thus making users of certain classes to be disadvantaged over others. This may destabilize the HWNs and even lead certain classes of users requiring relatively higher resources into complete extinction. Hence, the key for a sustainable HWN is a resource management scheme, which fairly allocates all network resources. Therefore, in this paper, first we propose an analytical model to characterize such unfairness and instability in HWNs. This approach is based on the theory of ecological multi-species multi-resource competition (MSMRC). Next, to counter the aforementioned instability and unfairness, we propose a new joint radio resource management (JRRM) scheme, MSMRC scheme, which is capable of ensuring the HWN's stability and maintain the coexistence of users of widely diverse requirements, even under the extreme situations. Results indicate that the MSMRC scheme also supports the sustainability of the HWN by helping it to withstand sudden disruptions.","PeriodicalId":262660,"journal":{"name":"2011 IEEE 22nd International Symposium on Personal, Indoor and Mobile Radio Communications","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124767334","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}

Until now, the coverage and potential of ITS have been restricted by the excessive cost of deploying the required road sensor and communications infrastructure. Our solution to this problem is focused on a novel integrated ITS Network Architecture where vehicles are the main infrastructure in the network. We propose The Connected Vehicle Infrastructure (CVI) for Intelligent Transportation Systems (ITS), where vehicles adapt to mobility changes to form stable vehicular clusters using a Network Criticality-based algorithm we have developed. Further, they build on their clusters to form more stable Mobile Networks, as part of the ITS network. Simulation results using NS-2 show that CVI clustering provides more stable clusters, lower handoffs, higher resilience to errors and better connectivity than popular density-based vehicle clustering methods. In addition, the overhead analysis of CVI shows that it achieves reasonable overhead compared to common clustering algorithms.","PeriodicalId":262660,"journal":{"name":"2011 IEEE 22nd International Symposium on Personal, Indoor and Mobile Radio Communications","volume":"05 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128562180","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 this problem a group of wireless clients are interested in obtaining a set of packets through cooperation, where each client initially holds a subset of packets. Unlike recent studies where cooperation is enabled through a fixed error free broadcast channel among fixed or stationary peers, we assume that peers move randomly between transmission rounds, have a limited transmission range and suffer from packet erasures. In this case giving an exact solution to the problem of minimum number of transmissions is difficult, if not impossible. Therefore, we propose two different heuristic transmission strategies to decrease the total number of transmissions compared to uncoded transmissions. We compare the performance of these two strategies in terms of energy consumption (total number of transmissions) by analysis and simulations. In particular, we show that when packet delivery delay is not an issue, the total number of transmissions can be dramatically decreased at the price of a small overhead.","PeriodicalId":262660,"journal":{"name":"2011 IEEE 22nd International Symposium on Personal, Indoor and Mobile Radio Communications","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129538639","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}
