This paper describes the possibility of molecular communication as a solution for communication between nanomachines. Nanomachines are artificial or biological nano-scale devices that perform simple computation, sensing, or actuation. Existing communication technologies cannot be applied to nano-scale communication between nanomachines due to diffi...
Conference Paper
In recent years, the notion of service overlay networks has been proposed as a promising solution for providing end-to-end QoS without changing the current Internet architecture. A major issue in deploying service overlay networks is determining how to allocate resources (such as link bandwidth) on a substrate network to overlay networks, while sat...

In recent years, service overlay networks have been proposed as a promising solution to provide end-to-end QoS without changing the current Internet architecture. In deploying service overlay networks, one major issue is how to efficiently allocate resources (e.g., link bandwidth) on a substrate network to each application with end-to-end QoS requi...

Molecular communication is one solution for nano-scale communication between nanomachines. Nanomachines (e.g., biological molecules, artificial devices) represent small devices or components that perform computation, sensing, or actuation. Molecular communication provides a mechanism for one nanomachine to encode or decode information into molecule...

We have proposed Molecular Communication (1)(2), a solution for nano-scale communication between nanomachines (e.g., biological molecules, artificial devices). Molecular communication provides a mechanism for one nanomachine to encode or decode information into molecules (information molecules) and to send the information molecules to another nanom...

Molecular communication is engineered biological communication (e.g., cell-to-cell signaling) that allows nanomachines (e.g., engineered organisms, artificial devices) to communicate through chemical signals in an aqueous environment. This paper describes the design of a molecular communication system based on intercellular calcium signaling networ...
Conference Paper
Distributed collaborative applications will be widely used in a future large-scale and dynamic network. Such applications require the capability of locating distributed network objects that better match query originator's criteria. In this paper, a discovery mechanism utilizing query originator's preference is proposed in order to locate objects pr...
Conference Paper
Full-text available
Distributed applications produce the need of locating distributed network objects (i.e., data, application or users) that meet a certain search criteria in a large-scale and dynamic network. We propose a discovery mechanism that is fully distributed (without any centralized entity) and adaptive to dynamic network environments. The proposed discover...
Conference Paper
Full-text available
We consider peer-to-peer and distributed networks where a large number of objects (such as users, information and applications) are distributed and they move dynamically. In such a distributed network environment, the ability to discover objects that match given query criteria, such as a set of keywords, is highly desirable. We propose a discovery...

... These actor nano-nodes will be able to interfere actively inside the body's and cells' functions creating the required changes in targeted body cells. Such methods will provide precise, uninterrupted and highly personalized intervention inside the human body when required [63,64]. ...
... We refer the reader to [113] for a more detailed discussion of existing literature, theoretical models, experiments, applications, and future directions in this field of MC. e) Other biological architectures: In addition to the biological transmission architectures described earlier, molecular motors' sliding on cytoskeletal protein structures, e.g., microtubules, and carrying cargo, i.e., vesicles, between cells is another option that has been considered by the MC community. In particular, Moore et al. [114] and Enomoto et al. [115] describe a high-level architecture design for MC over such channels. The comparison of active, i.e., molecular motors on microtubules, and passive, i.e., diffusion, vesicle exchanges among cells shows that active transport is a better option for intercellular MC in case of a low number of available vesicles and passive transport can support higher rates when large numbers of vesicles are available [116]. ...
... We consider a TDD scenario based on a molecular communication system with an embedded relay bionanomachine labeled with fluorescent molecules to deliver therapy drugs to the targeted tissues (cells). On the other hand, the deployment of the Internet of bio-nano things (IoBNT) paradigm as a remote control over the dissemination and exchange of information molecules via an embedded bionanomachines network is feasible for achieving important medical goals such as targeted drug delivery (TDD) systems and health care monitoring (HCM) applications [3,[7][8][9][10][11][12]. In addition, the molecular communication system is regarded as a promising tool for interconnecting embedded bionanomachines in the intra-body network (BAN). ...
... Accordingly, a transmitter in an MC system releases molecules into a fluidic medium, where the molecules travel through diffusion and/or drift, and a portion of them manages to reach an MC receiver. Typically, information molecules cause a certain reaction at the receiver, through which the receiver detects and decodes the transmitted information encoded into a distinguishable property of the molecules, such as their concentration, type, or release time from the transmitter [10], [11], [12]. ...
