Therefore, switching from one wireless technology to another, a process known as vertical handover, is often required. It is very important for vertical handover agents to know the performance of each candidate wireless network in order to switch into a network that fulfills the applications' requirements. In this work we present a performance evaluation of the main wireless technologies currently in use by mobile devices: Wi-Fi, WiMAX and UMTS. In our set of experiments we tested various schemes with different parameters for each technology, including modulation and channel bandwidth. Using the Network Simulator ns-2, we evaluate the performance of each network technology under different network congestion conditions. Results show that each technology offers different data rates, depending on the selected parameters. Moreover, we found that bandwidth availability status becomes of utmost importance for successful vertical handover.","PeriodicalId":311005,"journal":{"name":"International Workshop on Performance Monitoring, Measurement, and Evaluation of Heterogeneous Wireless and Wired Networks","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121846884","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}

Although until recently there has been a lot of interest in the mobility support of the technology, with the recent push for the Third Generation Partnership Project's (3GPP) Long Term Evolution (LTE), vendors are advancing WiMAX (in particular with the Wireless Metropolitan Area Network - Orthogonal Frequency Division Multiple Access (WirelessMAN-OFDMA) air interface specified by the IEEE 802.16 working group) as a fixed broadband replacement. For this market segment, Audio/Video (A/V) delivery is expected to be a key service offering. In this paper, we perform a detailed empirical evaluation using a state-of-the-art WiMAX testbed with multiple video flows directed at several Customer Premises Equipment (CPE) devices simultaneously. We employ the Evalvid framework and develop a methodology for its use in multi-client evaluations. We report our results for Variable Bit Rate (VBR) and Constant Bit Rate (CBR) video streams and draw conclusions.","PeriodicalId":311005,"journal":{"name":"International Workshop on Performance Monitoring, Measurement, and Evaluation of Heterogeneous Wireless and Wired Networks","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134118647","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}

Despite having a very similar functionality, Underwater Wireless Sensor Networks (UWSNs) exhibit several architectural differences with respect to the terrestrial ones, which are mainly due to the transmission medium characteristics (sea water) and the signal employed to transmit data (acoustic ultrasound signals). So, the design of appropriate network architecture for UWSNs is seriously hardened by the specific characteristics of the communication system. In this work we analyze several acoustic channel models for their use in underwater wireless sensor network architectures. For that purpose, we have implemented them by using the OPNET Modeler tool in order to perform an evaluation of their behavior under different network scenarios. Finally, some conclusions are drawn showing the impact on UWSN performance of different elements of channel model and particular specific environment conditions","PeriodicalId":311005,"journal":{"name":"International Workshop on Performance Monitoring, Measurement, and Evaluation of Heterogeneous Wireless and Wired Networks","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125833031","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}

Before applications can be deployed in such environments, it is important for developers to understand the potential quantitative behavior of the protocols that support their applications. Analytical models exist to describe the behavior of MANETs, but they are restricted to simplistic statistical models that represent either node mobility or link connectivity individually without considering the interplay of the two and other important aspects of MANETs. Our previous work has begun developing an integrated analytical framework which considers the impact the physical environment, network characteristics, protocols' behaviors, and the applications' communication patterns have on performance. In this paper, we focus specifically on analytical model to account for the subtleties of message queueing in MANETs. Our analysis explains a delay of a data packet in a mobile node under homogeneous conditions in a node mobility and traffic. This resulting model is expressed with parameters which are obtainable from systems, application designers and a operating environment. We describe our system and derive the delay model. We validate our analytical result through network simulation and discuss potential limitations of the model and future works.","PeriodicalId":311005,"journal":{"name":"International Workshop on Performance Monitoring, Measurement, and Evaluation of Heterogeneous Wireless and Wired Networks","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115838911","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}

Using autonomous and small wireless video sensor nodes can add a much higher level of flexibility, therefore extending the range of surveillance applications that could be considered and, more interestingly, can support dynamic deployment scenario. With such resource-constrained devices power conservation is an important issue but one must also ensure that the application's objectives are met. In this paper, we address the problem of adaptive scheduling of sensor node's activity to extend the network lifetime while fulfilling a critical surveillance application needs. We first present a distributed algorithm that ensures both coverage of the deployment area and network connectivity by providing multiple cover sets to manage Field of View redundancies. Then, we propose a multiple levels activity model that uses behavior functions modeled by modified Bezier curves to define application classes and allow for adaptive scheduling. Simulation results are presented to validate the performance of the proposed approach.","PeriodicalId":311005,"journal":{"name":"International Workshop on Performance Monitoring, Measurement, and Evaluation of Heterogeneous Wireless and Wired Networks","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133634827","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}
