A Mars Tumbleweed Rover is designed to use wind to propel a network of sensors across the Martian surface. While navigating the surface of Mars, the rovers' collect, aggregate, and communicate environmental and spatial sensor data. The Mars Tumbleweed program envisions releasing numerous autonomous rovers packed with sensors into a remote, desolate, and harsh dynamic environment, requiring a self-configurable, adaptable Wireless Sensor Network. This research examines the probability of sensor data loss between rovers as the range between them increases over time. The research shows the potential of selecting different network parameters to minimize the total power required to sense, process, and transmit data back to a base station. The impact of utilizing probabilistic analysis allows for optimal methods in the design of the WSN to better manage power consumption and maximize data collection over the course of the node lifetime. The research establishes a basic framework from which the general rules of power and network node distance can be established.","PeriodicalId":123545,"journal":{"name":"2015 11th International Conference on the Design of Reliable Communication Networks (DRCN)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115381130","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 paper, we consider the problem of managing playout stalls experienced by multiple clients streaming different videos from a cellular base station. We build on our prior work [1], where we formulate an epoch based lead aware multiple video transmission (LMVT) problem to minimize the total number of playout stalls experienced by mobile clients. In [1], [2], we show that the LMVT problem is NP-hard and propose a pseudo polynomial dynamic programming solution and a simple greedy heuristic to solve the problem. In this paper, we first show that even a simpler and less restrictive version of the LMVT problem remains hard. We then design a fully polynomial time approximation scheme (FPTAS) for the LVMT problem by demonstrating that it is equivalent to the Santa Claus Problem [3], [4]. The FPTAS provides a bounded performance guarantee, differing by a factor of 1/1+ϵB from the optimal solution (where B is the number of time slots in an epoch and ε is a small constant).","PeriodicalId":123545,"journal":{"name":"2015 11th International Conference on the Design of Reliable Communication Networks (DRCN)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125450370","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}

We present a novel framework for real time network traffic anomaly detection using machine learning algorithms. The proposed prototype system uses existing big data processing frameworks such as Apache Hadoop, Apache Kafka, and Apache Storm in conjunction with machine learning techniques and tools. Our approach consists of a system for real-time processing and analysis of the real-time network-flow data collected from the campus-wide network at the University of Missouri-Kansas City. Furthermore, the network anomaly patterns were identified and evaluated using machine learning techniques.

However, such networks have to be administered and managed by human administrators. The process of such administration, as it becomes increasingly complex, itself poses a challenge to protocols and systems designed to enhance network reliability. Several studies of highly reliable systems have shown that human operator error can account for 20-70% of system failures, and as the system become more reliable, the human factor gains increasing significance. Nevertheless, efforts to design reliability measures have remained largely disjoint from considerations of the human process of network administration. In this position paper, we describe some preliminary effort to examine the question of whether such joint consideration can be useful. We employ the first stages of a Grounded Theory approach to study network administration and management workflows in order to understand their impact in network reliability. Based on our study, we advance the proposition that the future of network reliability engineering must actively address the human process of system administration and management and concommittant misconfigurations.","PeriodicalId":123545,"journal":{"name":"2015 11th International Conference on the Design of Reliable Communication Networks (DRCN)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133632433","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}

DASH enables the video player to adapt the quality of the multimedia content being downloaded in order to match the varying network conditions. The key challenge with DASH is to decide the optimal video quality for the next video segment under the current network conditions. The aim is to download the next segment before the player experiences buffer-starvation. Several rate adaptation methodologies proposed so far rely on the TCP throughput measurements and the current buffer occupancy. However, these techniques, do not consider any information regarding the next segment that is to be downloaded. They assume that the segment sizes are uniform and assign equal weights to all the segments. However, due to the video encoding techniques employed, different segments of the video with equal playback duration are found to be of different sizes. In the current paper, we propose to list the individual segment characteristics in the Media Presentation Description (MPD) file during the preprocessing stage; this is later used in the segment download time estimations. We also propose a novel rate adaptation methodology that uses the individual segment sizes in addition to the measured TCP throughput and the buffer occupancy estimate for the best video rate to be used for the next segments.","PeriodicalId":123545,"journal":{"name":"2015 11th International Conference on the Design of Reliable Communication Networks (DRCN)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122341930","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 next architecture, Streamlined, replaces the hub-and-spoke topology of Baseline with a flat topology and is also more judicious in its restoration design. Our detailed study shows significant cost savings for the Streamlined architecture compared to the Baseline. We reduce the cost further in our third proposed architecture: Ethernet Enabled IP core (EEIPC) consisting of OTN switches (with and without packet switching) and without any backbone routers or MPLS switches. Our results also demonstrate that we can achieve significant reduction in switching costs but reducing cost of transport remains a significant challenge.","PeriodicalId":123545,"journal":{"name":"2015 11th International Conference on the Design of Reliable Communication Networks (DRCN)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124918304","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 model extends over both the “wireline” backhaul and wireless (radio access) portions of the network, i.e. from the mobile telephony serving office (MTSO) to the users of wireless devices. The model captures failures of network elements in the backhaul, such as switches, network access and termination devices, uncertainty in the routing of fiber feeders, and failures of base station equipment in the radio access part. It also includes effects of path loss, interference, and traffic variability in the radio access, and represents the migration of wireless devices among cell sites in response to outages in the overall network. The last part of the model represents a population of (stationary) wireless users randomly distributed in a geographical area, but with density in accordance with measured cell site traffic. The model is analyzed with the “most probable states” method for performability evaluation to compute approximate probability distributions for metrics such as cell site disconnection due to failures in the backhaul, backhaul link utilizations, loss of coverage for wireless users, and a “service acceptability” metric. The results are useful for assessing the cost vs. performance of a cellular network design.","PeriodicalId":123545,"journal":{"name":"2015 11th International Conference on the Design of Reliable Communication Networks (DRCN)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131480262","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}
