Research on dynamic routing algorithm of the combat collaboration communication network

The military communication system is the key element to make a victory in the battle. In general, the combat collaborative communication network is a multi-hop and autonomous system, which is composed by a group of mobile nodes with wireless communication ability. The network has some features such as no center, self-organizing, multi-hop routing and dynamic […]

Multi-devices composition and maintenance mechanism in mobile social network

In mobile social network, it is a critical challenge to select an optimal set of devices to supply high quality service constantly under dynamic network topology and the limit of device capacity in mobile ad-hoc network (MANET). In this paper, a multi-devices composition and maintenance problem is proposed with ubiquitous service model and network model. […]

Designing a passive star optical network for the India-based Neutrino Observatory

The India-based Neutrino Observatory (INO) uses an iron calorimeter (ICAL) as the neutrino detector. The ICAL consist of 28, 800 resistive plate chambers (RPCs) that generate event data at ~ 650 kbps, for an aggregate of 18 Gbps at the backend. Implementation of a triggerless detection scheme will increase this by a factor of 20. We describe […]

On Availability-Performability Tradeoff in Wireless Mesh Networks

It is understood from past decade of research that a wireless multi-hop network can achieve maximum network throughput only when its nodes operate at a minimum common transmission power level that ensures network connectivity (availability). This point of optimality where maximum availability and throughput is guaranteed in an interference-optimal network has been the basis of numerous design […]

Future Directions in Cable Networks, Services and Management

This chapter describes cloud, virtualization, software-defined networking (SDN), and self-managed concepts, architectures, and their building blocks, as possible future directions for multiple-system operator (MSO) networks and services. Cloud computing technologies are emerging as infrastructure services for provisioning computing and storage resources on demand in a simple and uniform way. Cloud-based virtualization allows for easy upgrade and migration […]

Social-Aware Stateless Routingin Pocket Switched Networks

Existing social-aware routing protocols for packet switched networks make use of the information about the social structure of the network deduced by state information of nodes (e.g., history of past encounters) to optimize routing. Although these approaches are shown to have superior performance to social-oblivious, stateless routing protocols (BinarySW, Epidemic), the improvement comes at the cost of […]

Cellular software defined networking: a framework

Today???s mobile customers desire to remain connected anywhere, at any time, and using any device. This phenomenon has encouraged mobile network operators to build complex network architectures by incorporating new features and extensions, which are harder to manage and operate. In this article we propose a novel and simplified architecture for mobile networks. The proposed […]

Design and Evaluation of the Optimal Cache Allocation for Content-Centric Networking

Content-Centric Networking (CCN) is a promising framework to rebuild the Internet’s forwarding substrate around the concept of content. CCN advocates ubiquitous in-network caching to enhance content delivery, and thus each router has storage space to cache frequently requested content. In this work, we focus on the cache allocation problem, namely, how to distribute the cache capacity […]

Mobility-aware QoS assurance in software-defined radio access networks: An analytical study

Software-defined networking (SDN) has gained a tremendous attention in the recent years, both in academia and industry. This revolutionary networking paradigm is an attempt to bring the advances in computer science and software engineering into the information and communications technology (ICT) domain. The aim of these efforts is to pave the way for completely programmable […]

An Evolutionary Game Theory-Based Approach to Cooperation in VANETs Under Different Network Conditions

Vehicular Ad hoc NETworks (VANETs) belong to a class of complex networks due to constant addition and deletion of nodes. Stimulating cooperation in these networks is a research challenge due to this uncertainty. The reason is that the node behavior is highly influenced by the neighborhood structure. Game theory has been significantly used to model ad hoc […]
