The IRMA approach is motivated by the fact that the overall performance achieved by conventional layered approaches (802.11 MAC combined with independent ad hoc routing protocols) is significantly lower than the underlying network capacity. We propose to integrate the routing and MAC into a single protocol layer and use joint optimization techniques to establish end-to-end path and TDMA schedules for flows across the network. This approach achieves non-conflicting allocation of channel resources based on global or local traffic flow specifications and the network graph. The proposed method not only establishes interference-free MAC link schedules, but also helps to find optimal routes which can route around congested areas of the network. Two specific IRMA algorithms are proposed and evaluated in this paper. The first method solves min-hop routing, then optimizes link scheduling based on routing results and real-time flow demands. The second approach attempts to optimize routing and scheduling decisions simultaneously, using available MAC bandwidth information to route around congested areas. Both centralized and distributed algorithms based on these methods are proposed and evaluated with detailed simulations. Results show significant 2-3x improvements in network throughput when compared with baseline 802.11-based mesh networks using independent routing protocols.","PeriodicalId":346269,"journal":{"name":"2008 International Symposium on a World of Wireless, Mobile and Multimedia Networks","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121427656","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}

The database is copied to all mobile devices, and in case that a position estimate is needed, the device compares its currently measured radio characteristics with all the database entries. In this paper, we present two on-demand fingerprint selection algorithms to avoid the cumbersome and time-consuming approach of manually copying all fingerprints. Our algorithms only request those fingerprints from the database that are currently required to compute a position. The two algorithms differ in the way they shape the region for which fingerprints are requested. On-demand selection also allows storage-restricted mobile devices to utilize the positioning system. We carefully evaluate our algorithms in a real-world experiment. The results show that our algorithms do not harm the position accuracy of the positioning system. In addition, we analyze the space requirements of our algorithms and show that the typical constraints of mobile devices are met.","PeriodicalId":346269,"journal":{"name":"2008 International Symposium on a World of Wireless, Mobile and Multimedia Networks","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130715158","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}

The default values of the QoS parameters in EDCA, contention window (CW), arbitration Interframe Space (IFS) etc only yield good performance for few scenarios. We first propose a simple adaptation scheme, called a-EDCA, where the access point adapts the CWs based on the network conditions. The main contribution of this work is the second approach, called i-EDCA, where we make modifications to the backoff phase of EDCA and introduce a random IFS scheme. Simulation results show that both approaches result in stable capacity ratios between priority classes and very high channel utilization, compared to EDCA, when the number of stations is increased. Moreover, i-EDCA yields close to optimal channel utilization for a large number of scenarios without any need of adapting the parameters. In i-EDCA, the capacity for each class is directly proportional to its CW. Results also show that i-EDCA has improved fairness and prevents low priority classes to be starved under higher loads, a problem found in EDCA.","PeriodicalId":346269,"journal":{"name":"2008 International Symposium on a World of Wireless, Mobile and Multimedia Networks","volume":"164 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114367833","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}
