Rescue teams require information about victims in need of help rapidly to improve survival rate at the time of disaster. Emergency Rescue Information Sharing System gathers and provides the information with a framework called METHANE in addition to efficient wireless link's selection using OpenFlow. However, it is difficult for those who rescue the victims except for the rescue teams to recognize...
Conventional datacenters, based on wired networks, entail high wiring costs, suffer from performance bottlenecks, and have low resilience to network failures. In this paper, we investigate a radically new methodology for building wire-free datacenters based on emerging 60GHz RF technology. We propose a novel rack design and a resulting network topology inspired by Cayley graphs that provide a dense...
IoT-based applications are becoming more popular and provide effective solutions for many real time problems. In this research, real-time monitoring system for residential energy meter is proposed. The presented system provides ubiquitous and continuous access to energy consumption to the consumer by exploiting the advancement of IoT technology. The proposed system is cost effective as it requires...
Currently we can witness how unmanned aerial vehicles (UAVs) have suddenly become an active research area, and are enjoying widespread acceptance, while also starting to play a relevant role in many areas of our society. Nonetheless, despite significant progress was made in recent years, many more improvements are expected in a near future. In this paper we address the issue of inter-UAV communications...
Aggregating common-path network flows (in the network interior) helps in improving the applications delivery performance. From the network edge perspective, the sender and receiver-ends of the respective applications need to have a typical one-to-one mapping. An aggregation framework in the network therefore needs an effective forking to maintain the one-to-one mapping of the flows. In this demo,...
Privacy protection has been in intensive concerns in Location Based Service (LBS). In existing research, tremendous efforts have been brought to obfuscation techniques and developing new anonymity to preserve the location privacy. However, these techniques may either sacrifice the service accuracy or rely on a trusted third party. To deal with this, in this paper, we propose a decentralized data forwarding...
The large available bandwidths, demonstrations of fully-integrated silicon transceivers and small physical antenna size make mm-wave frequencies attractive for wireless links within a server chassis. In this paper, we focus on studying the feasibility of a mm-wave wireless link within a commercial microserver chassis for high data-rate links and for management and monitoring. Such servers have reflective...
In this article we have presented experimental results to evaluate the effectiveness of wireless fingerprinting based on Received Signal Strength Indicator(RSSI). Experiments are conducted on a real world water treatment testbed. Results indicate unique vantage point for Cyber Physical System(CPS) settings as the wireless environment is comparatively static hence the significance of signal strength...
For high spectrum usage, some independent wireless communication systems should share multi-channel environment. An offloading effect over multi-channel makes system throughput enhanced. A multi-channel access based on channel activities of other systems, which are channel occupancy ratio (COR), is important. The estimation of COR needs a traceability to the transition of COR. In software define radio,...
A port-Hamiltonian model of the traffic dynamics for a wireless communication system was developed in our previous work. The developed model takes into account various wireless communication aspects: such as a wireless path loss model, the characteristics of a wireless communication system, mac layer and network layer protocols, antenna design, latencies, buffer dynamics, acknowledgment rate and so...
Periodic broadcasting has achieved prominent performance in VoD (Video on Demand) service in wired network. However, the development of wireless VoD service still has gone on hard and slowly in comparison to the rapid growth of mobile video service. In this paper, we propose a scalable video streaming method HQOBA (Heterogeneous Quality-Oriented Bandwidth Allocation) to address the problems in wireless...
Advances in technology have enabled wireless devices to monitor and provide information than ever before. These sensors/actuators can be incorporated into any device to provide the user an immersive experience which include services such as connected-consumer, e-Health and smart transportation etc. Bluetooth Smart has emerged as popular wireless communication technology for such devices. The Received...
Peer-to-Peer(P2P)-based Video-on-Demand application has gained more attentions recently. Due to the system complexity, there are still many challenges for practical deployment such as peer selection. Previous works focused on how to find the most suitable service or the request response scheme on the peer-side. In this paper, we study the request response scheme on the server-side by discussing three...
As a data exchange specification for industrial communication, OPC Unified Architecture (OPC UA) solves the access uniformity and standardization problem of data communication between the plant floor and the enterprise, and meets the needs of enterprise information in a high degree of connectivity. OPC UA protocol can be extending to the low-layer of the industrial wireless network systems, and then...
The system proposed is a door unlocking system containing multiple doors any of which can be used to access a certain zone e.g. a laboratory or library. The system is implemented using a central server which contains a central database gathering all the information about the authorized personnel. The hardware components required are RFID reader, passive RFID tags, wireless transmitter & receiver...
Mobile cloud computing is increasingly being used in recent times to offload parts of an application to the cloud to reduce its finish time. However, quality of offloading decisions depend on network conditions and hence many offloading solutions assume that MAC layer retransmissions will tackle transient frame errors. This can lead to suboptimal solutions, as well as, degrade service level guarantee...
Recently, a new class of decentralized random coded caching schemes have received increasing interest, as they can achieve order-optimal memory-load tradeoff through decentralized content placement when the file size goes to infinity. However, most of these existing decentralized schemes may not provide enough coded- multicasting opportunities in the practical operating regime where the file size...
In this paper, we investigate the problem of robust congestion control in infrastructure-based cognitive radio networks (CRN). We develop an active queue management (AQM) algorithm, termed MAQ, based on multiple model predictive control (MMPC). The goal is to stabilize the TCP queue at the base station (BS) under disturbances from the varying service capacity for secondary users (SU). The proposed...
Wireless EEG monitoring systems have been successfully used for seizure detection outside clinical settings. The wireless EEG sensor nodes consume a considerable amount of battery energy to acquire, encode and transmit the data to the server side. In this paper, we introduce energy-efficient monitoring systems to increase the sensors' battery lifetime. Specifically, we propose a feature extraction...
Wireless content delivery networks (WCDNs) have received attention as a promising solution to reduce the network congestion caused by rapidly growing demands for mobile content. The amount of reduced congestion is intuitively proportional to the hit ratio in a WCDN. Cooperation among cache servers is strongly required to maximize the hit ratio in a WCDN where each cache server is equipped with a small-size...
