A broadband GaAs MMIC double balanced diode ring mixer was designed in the paper. The mixer covers radio frequency (RF)/local oscillator (Lo) operating frequency range from 3 GHz to 10 GHz and the bandwidth of intermediate frequency (IF) signal is from 10MHz to 4 GHz. The mixer gets a conversion loss less than 12 dB and decent LO to RF isolation of nearly 30 dB, and the mixer also obtains good linearity...
This paper identifies that the anycast communication pattern is needed in the Machine Type Communications (MTC), where there could be multiple MTC devices being deployed in the same area for the same type of data, the client only cares about the data being retrieved but not where the data comes from. Currently the MTC server can provide such anycast service, but with large signaling overhead and bandwidth...
The subscription and notification communication pattern is commonly used in IoT applications, accompanied with notification conditions, for consumers to get notified of the interested information. The existing pub/sub solutions do not suit the IoT data subscription and notification triggered by the value change over the time. The paper proposes the in-network aggregation and distribution of conditional...
One discriminating characteristics of data in the Internet of Things (IoT) applications is that it may have multiple producers (e.g. many sensor devices deployed in an area to sense the same information). It is very important that the name resolution service is able to provide the proper producer selection based on client's criteria and the producers' contextual information. The paper proposes a robust...
With the vision of deployment of massive Internet-of-Things (IoTs) in 5G network, existing 4G network and protocols are inefficient to handle sporadic IoT traffic with requirements of low-latency, low control overhead and low power. To suffice these requirements, we propose a design of a PHY/MAC layer using Software Defined Radios (SDRs) that is backward compatible with existing OFDM based LTE protocols...
In this paper, we propose a decentralized mobility support architecture, with micro-level name resolution, for information centric networking (ICN) to better manage host mobility, and respond quickly to handover events to avoid data loss. Proposed architecture utilizes localized anchors, carrying new data structures, during packet forwarding to aggregate mobile flows and provide a combination of stateful...
The challenging requirements of 5G, from both the applications and architecture perspectives, motivate the need to explore the feasibility of delivering services over new network architectures. As 5G proposes application-centric network slicing, which enables the use of new data planes realizable over a programmable compute, storage, and transport infrastructure, we consider information- centric networking...
This paper proposes mechanisms to support basic, as well as conditional subscription/notification communication pattern in the Information Centric Networks (ICN), which still leverage and build on the ICN architecture and fundamental design principles with minimum change to the protocols. The proposed new interest message integrates content retrieve request, subscription and notification functions,...
Although Information Centric Networking (ICN) has been identified as promising candidate for the Internet of Things (IoT) architecture, the emerging of various IoT use cases poses great challenges to the ICN architecture. The new characteristics of IoT data and clients' IoT data retrieval require the ICN infrastructure to be more intelligent and advanced capabilities. This paper proposes enhanced...
We present a novel approach to support stateless forwarding in information centric networks with emphasis on the CCN/NDN architectures by proposing a space-efficient in-packet filter based on the encoded counting bloom filter. Proposed solution avoids the typical pitfalls of using classic Bloom Filters by significantly reducing the false positive transmission attempts, while supporting reliable and...
In this paper, we propose an overlay routing architecture for information centric networks that operates on hash-based groupings of content routers and namespaces. Proposed architecture creates hash-based clusters within each domain using globally shared hash functions, and distributes the global namespace to different clusters. In doing so, we achieve the following notable improvements in control...
Differential evolution (DE) is a very simple and effective stochastic search algorithm, which obtains various performances with different parameter and searching strategy configurations. DE with an individual-dependent mechanism (IDE) is a recently proposed DE variant, which includes an individual-dependent parameter (IDP) setting method and an individual-dependent mutation (IDM) strategy. In this...
IoT resource registration and lookup interfaces have been specified for Resource Directory (RD) with defined resource link format in IETF standard. However, it has many drawbacks due to the nature of the centralized architecture. This paper proposes an ICN-based distributed RD architecture. The proposed distributed IoT resource discovery and routing mechanisms allow and reuse the existing RD resource...
In Internet of Things (IoT) applications such as smart home and remote car maintenance, etc., a client usually requests a content with certain contextual requirements. Such contextual requirements need to be fulfilled by the returned content, otherwise the network bandwidth is wasted in transmitting the content that the client does not want. The Information-Centric Networking (ICN) has regarded as...
In the urban city life, a human usually uses his/her owned user equipment (UE) to request services provided in smart cities. In order for UEs to communicate with the public service providers, the network traffic is generated in the cellular network (e.g. Long Term Evolution (LTE) network) and the Internet very frequently. And the returned results cannot be shared among UEs although they may request...
The rapid growth in IoT deployment has posed unprecedented challenges to the underlying network design. We envision tomorrow's global-scale IoT systems should support global device reach-ability, mobility, diverse communication patterns, and resource efficiency. Existing solutions either rely on IP protocols that do not have efficient mobility support, or seek application-layer optimizations that...
Many approaches have been proposed to build a unified IoT platform where physical and digital objects are accessible by applications crossing different organization and domains, and are based on IP-overlay architecture. These solutions inherit the constraints of the current internet, especially in terms of naming, heterogeneity, mobility and security. In this paper, we propose a new Information-Centric...
Current video conferencing design based on client-server or peer-to-peer architecture do not scale to large number of users. ICN addresses this through network-based multicast built on applications semantics. Considering the pull-based content primitive, scalability is also required to learn the current state of the media names (text, audio, video) of participants considering adhoc join/leave behavior...
In this paper, we propose a novel solution to scalable forwarding problem in content centric networks (CCN) that relies on the use of hash-based content names for packet forwarding. Proposed approach continues the hierarchical naming format of CCN by converting human readable name prefixes to their hashbased counterparts to enable faster packet processing at the content routers, with additional proposed...
