Equipped with the ability to collect images/video streams from surrounding environments, many interesting applications will emerge through the use of WMSN. One of the key targets of a WMSN application is reconstructing the Plenoptic function by using collected images. However, due to the characteristics of wireless channels, this task is challenging. In this paper, a reliable transport protocol for WMSN is presented. This protocol utilizes JPEG stream semantics to distinguish the importance of different parts within the stream, and schedules the transmission based on the importance of the information. In order to investigate the performance of the proposed protocol, a novel image mosaicking algorithm is used as a sample WMSN application. The experimental results show that the proposed protocol and application can offer snapshots of the interested environment with larger field-of-view (FOV) and with little delay. The quality of the view can be improved gradually with the arrival of the data representing the higher frequency part of the images.","PeriodicalId":218005,"journal":{"name":"2008 33rd IEEE Conference on Local Computer Networks (LCN)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121334971","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}

Particularly, in sensor and actor networks, providing certain delay bounds is crucial for the actors as they perform their actions based on the received data from sensors. The usefulness of the content from sensors is based on its timeliness. In this paper, we present Ad Hoc On Demand Delay Constrained Distance Vector Routing (AOD2V) which is an extension to the widely used routing protocol AODV for providing delay constrained data delivery in mobile sensor/actor networks. The admission control is based on Delay-EDD scheduling algorithm. The idea is to reserve the resources while routes are being determined in the route discovery phase of AODV. The reservation considers the service time at each node till the destination node. As long as the cumulative delay which is received at the destination is less than the desired delay bound, a positive acknowledgment is sent back to all the nodes on the path with AODVpsilas route reply packet and the connection request is admitted. Otherwise, the connection request is rejected and the reserved resources at the intermediate nodes are released. When the data transmission starts, Earliest Deadline First (EDF) scheduling algorithm is used to determine the departure order of the packets at the intermediate nodes. The performance of AOD2V is validated through extensive simulations and has been shown to outperform AODV in terms of delay and data delivery ratio without introducing any major extra overhead.","PeriodicalId":218005,"journal":{"name":"2008 33rd IEEE Conference on Local Computer Networks (LCN)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126943699","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}

This paper proposes a new power management framework called Data-Driven Power Management (DDPM) as the infrastructure for integrating various energy efficient techniques, such as the approximate querying and the sleep scheduling. By utilizing the beneficial properties of these techniques, we can achieve better energy efficiency while still meeting the application specific criteria, such as data accuracy and communication latency. The distinguishing feature of DDPM is that it starts by exploiting the natural tradeoff between the quality of the sensor data and the energy consumption, and then it generates a precision-guaranteed estimation for each sensor node as its maximum sleep time. Eventually deterministic schedules can be made by the DDPM based on these estimations. We further propose two decentralized algorithms so that the undesirable communication delays caused by staggered local sleep schedules can be avoided. The experimental results show that the nodespsila sleep times can be significantly increased while incurring only a minor rise in latency.","PeriodicalId":218005,"journal":{"name":"2008 33rd IEEE Conference on Local Computer Networks (LCN)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125502969","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}
