The overload of IP address is regarded as an important reason to create routing scaling issues. There have been several proposals to address this problem, such as Shim6, HIP and LISP. LISP, as one of the most representative proposal, separates IP address into Endpoint Identifier (EID) and Routing Locator (RLOC). To map identifiers onto locators, there must be a mapping system. In this paper, we propose...
The current work deals with the problem of resource management in P2P networks. The topological properties of the overlay network are critical factors that dominate the performance of P2P networks. The inverse Kautz digraph is a good topology to construct the overlay network. We discuss an efficient DHT-based overlay network (MREIK) with Byzantine fault tolerance. MREIK based on many rings which embeds...
Today's Internet is facing many problems which did not take into account in its initial design, such as routing scalability, mobility and security. No matter evolutional or revolutionary solutions that are proposed in recent years, a recognized promising direction is to separate customer network from core network and separate identification from location. In this paper, we sketch out an architecture...
As an infrastructure for data distribution, overlay networks have to feature efficient routing and adequate robustness to achieve fast and accurate data distribution in the environment with node churn. Considering that the existing overlay networks mostly focus on single optimization objective and fail to ensure routing efficiency and robustness simultaneously, a hybrid overlay network for content-based...
Large-scale P2P systems typically have hundreds of thousands of peers that involve frequent dynamic activities. Empirical studies have shown that participating nodes in P2P systems are not equivalent. Such heterogeneity has been taken into account in the design of P2P systems. In this paper, to achieve better scalability and improve the routing performance of REIK, we design a novel hierarchical REIK...
This paper presents a real world case of implementing a sensor network for fulfilling the requirements of gas meter application. We propose a hierarchical network, which includes the functionalities such as receiving, transmitting, routing, auto-reconfiguring, scheduling, and deep-sleeping under the stringent requirement of power consumption. We are currently conducting tests on this system and collecting...
Future generations of mobile operator networks, based on an all-IP-based flat architecture and a multitude of different access technologies, require a proper IP-based mobility management in place. In this article, a scalable and completely distributed mobility management is presented which is based on a Distributed Hash Table data structure. The Distributed IP Mobility Approach (DIMA) remains completely...
