Wireless sensor networks (WSNs) are useful for gathering information from the environment, either periodically for monitoring purposes or when certain events need to be detected. Since the wireless communication range of each sensor node is limited, data is propagated in a multi-hop manner until it reaches one or more specific sink nodes. However, sensor nodes usually employ a sleep scheduling mechanism...
Ambient information environments will lead to a large degree of interactions among the environment and human users through integrating heterogeneous services, devices, and networking elements. The main goal of such systems is to provide users with services they desire and improve their living situation. Generating ambient environments faces several challenges, such as designing the appropriate platforms...
Recently societal requirements have become so complicated that the current Internet is facing many challenging issues to overcome. Several task forces have been working on research on the future Internet in a clean slate manner and mobility management is one of the key issues to be considered. Mobility management in the future Internet is still designed in an “all-in-one” way where all management...
For the emerging concept of network virtualization where a multitude of virtual networks (VNs) coexist, the main challenge is to isolate and control the resources allocated for individual virtual networks. Realizing such resource allocation requires deliberate design of the router enhanced specifically for handling a large number of virtual network flows. This paper discusses fundamental challenges...
In the future, wireless sensor networks (WSNs) are expected to play an important part in our everyday life. Sensor nodes are becoming more and more miniaturized, equipped with radio transceivers, and deployed in large quantities. However, due to their limitations in computational and communication capabilities, clustering techniques are usually applied for energy conservation, where designated nodes...
In this paper we discuss the application of a biologically-inspired approach for path selection in overlay networks under the constraints of in-order packet delivery. We apply the concept of attractor selection by modeling the path selection process in multipath overlay as a stochastic dynamical system that instantaneously converges to a sufficiently good solution utilizing the system inherent noise...
Television over the Internet (IPTV) is regarded as the killer application for next generation networks (NGN). While the ITU is currently moving toward the standardized of IPTV, several existing applications like Joost and Zattoo are currently already providing a large amount of video content to Internet users. In this paper we study some popular video content delivery mechanisms and characterize them...
In recent years, interesting phenomena were revealed where the inherent noise enhances the adaptability of a system to its changing environment in a resilient manner. The application of such methods can be found in a wide variety of fields, from biology to engineering. In this paper we discuss the application of noise-assisted mechanisms to control and manage information networks. Specifically, we...
In this paper, we discuss robustness issues of a biologically inspired routing protocol for mobile ad hoc networks and the influence it has on the quality of service (QoS) in the system. Contrary to fixed network structures, ad hoc networks are susceptible to frequent topology changes due to the mobility and churn of the participating nodes. Our goal is therefore to provide fast recovery from connectivity...
In this paper we propose MARAS, a biologically-inspired method for routing in a mobile ad-hoc/sensor network environment. We assume that all nodes have no explicit knowledge of the network topology, except for their coordinates and the neighboring nodes within an RF transmission range. MARAS then selects the next hop for forwarding a packet towards a destination node which is best suited depending...
In this paper we discuss the effects of symbiosis when using an attractor selection model for multi-path routing in an overlay network. Attractor selection is a biologically inspired approach which is found in E. coli cells to self-adaptively react to changes of a nutrient in the environment. It is driven by noise and we present its application to selecting the paths in an overlay network for the...
