Article
This article presents a semantics-based context-aware dynamic service composition framework that composes an application through combining distributed components based on the semantics of components and contexts of users. The proposed framework consists of Component Service Model with Semantics (CoSMoS), Component Runtime Environment (CoRE), and Se...

Conference Paper
This article describes two branches of biologically inspired approaches to networks; biologically inspired computer networks and biologically inspired nanoscale biological networks. The first branch, biologically inspired computer networks, applies techniques and algorithms from biological systems to design computer networks. The second branch, bio...

Dynamic composition of complex services from primitive components brings flexibility and adaptability to future applications. By properly selecting and combining components on demand, applications would adapt to individual user preference and would consider available context information. Existing service composition systems often require users to r...
Article
The ability to reconfigure network applications and distributed systems (e.g. middleware) to adapt to changing network conditions is becoming more important. This paper describes our research efforts regarding dynamic reconfiguration of network applications and middleware. We first describe our approach to reconfigure network applications through a...

... Substantial amount of research activity has been devoted in recent years towards developing the concept of nanocommunications , including establishment of an IEEE study group P1906 A significant body of research in the area of nanocommunications focuses on specific communication activities that take place among living organisms at the microbial level, or communication pertaining to molecular propagation [2][3][4][5]. There is also a very large body of research dealing with nanoscale processes within living organisms at inter-and intracellular levels [6] that can provide insight into nano-scale communications. ...
... We present some advantages and drawbacks for both proactive and reactive integration approach. An extensive comparative study of the two approaches is presented in [10] to which we refer the reader for further information. ...
... The hybrid variant uses an additional semantic wrapper during service discovery (Fujii and Suda, 2009). The registration of a service by a provider is still syntax based using a specific name in the registry. ...
... Various factors, models, algorithms, and approaches have been proposed [2][3][4]. In particular, algorithms include dynamic programming algorithms [5][6][7], and heuristic and meta-heuristic algorithms such as Genetic Algorithms (GA) [8] and Ant Colony Optimization (ACO) algorithms [9]. These algorithms are useful and effective for solving small-scale and static service composition problems, but they have inherent shortcomings that are difficult to overcome such as slow convergence speed, poor adaptive ability, and easy to fall into local optimal solutions. ...
... The objective of our long-term research is to develop autonomous adaptive agents for large scale, network-based or Internet-based, ubiquitous, distributed computing environments. In order to accomplish this goal, we have come up with a novel architecture called the 'bio-inspired reconfigurable and adaptive agent framework', which is attributable to several biological concepts and mechanisms151617. In this paper, the author describes a self-organizing system framework that allows for highly distributed and dynamic network applications using autonomous adaptive agents. ...
