In CSMA, spatial reuse can be improved by suitably changing the carrier sense threshold (CST). If the increased CST does not incur collisions and helps concurrent transmissions from multiple devices, this improves the throughput of the wireless LAN. For example, when there are two APs and multiple devices exist near each of them, each AP can transmit a frame simultaneously without causing collisions of frames since each device can receive a frame from its associated AP with a high signal power and the interference from another AP is small. In this paper, we propose a system which improves the throughput in CSMA/CA based wireless LANs by controlling the CST values of APs according to positions of mobile hosts. In the system, the CST values of multiple APs are dynamically configured by a controller which has a camera for obtaining the current positions of mobile hosts. The proposed system improves the throughput in WLAN 58% in comparison with basic DCF in a LAN where two APs are arranged at an interval of 50 m and two devices exist within 10 m from each AP.","PeriodicalId":251023,"journal":{"name":"2015 Eighth International Conference on Mobile Computing and Ubiquitous Networking (ICMU)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133774030","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 post-disaster contexts however, cloud-based mapping services and data may be unavailable because of network challenges. Disruption Tolerant Network (DTN) architectures have been proposed for data sharing in challenged networks. However, map generation may be too complex for individual DTN nodes given their limited computing resources. To generate and share maps of disaster areas, we present DTN MapEx, a distributed computing system for mapping that operates over a DTN. DTN MapEx distributes disaster map data and map generation tasks to multiple nodes to minimize individual computational loads. In the system, responders and volunteers act as mobile sensing nodes. They log the GPS traces of their traversed paths and collect disaster area map data such as the coordinates, images, and assessments of points-of-interest. The mobile nodes then route their collected data and a task request through the DTN to pre-deployed, fixed Computing Nodes. The Computing Nodes aggregate the data to generate a map and opportunistically route it back to the network. To reduce complexity, mapping tasks and data are divided amongst Computing Nodes based on their current computational load. Computing Nodes periodically update the DTN about their current loads. Mobile nodes use these updates in deciding where to allocate their task requests and data. In this paper, we present the design of DTN MapEx and perform initial evaluations on its feasibility in disaster scenarios.","PeriodicalId":251023,"journal":{"name":"2015 Eighth International Conference on Mobile Computing and Ubiquitous Networking (ICMU)","volume":"323 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116777020","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}
