Distributed Hash Tables (DHTs) have emerged as the most popular scheme in the P2P network, which have drastically changed the way we share resources and gather information. In order to solve the problem of search flexibility In DHT, an improved lookup and routing protocol based on Content Addressable Networks (CANs) is proposed, which not only preserves CANs' simplicity, but also achieves a resilient...
Energy aware routing via rerouting traffic or traffic aggregating has received wide attention in the last decade. It is important and challenging to take network reliability into consideration to enhance the resilience to failures at the same time. In this paper, we aim to minimize energy expenditure while ensuring network reliability by restoration. As each request has an active path and disjoint...
Vehicular Ad hoc Networks (VANETs) is a technology to support communication among vehicles or between vehicles and infrastructure in order to exchange traffic information and avoid accidents. Many applications in VANETs need to transmit messages to vehicles within a specific geographic region. This behaviour is called Geocast. Several Geocast routing protocols have been proposed for VANETs. In this...
As one of the most important enablers of Intelligent Transportation System (ITS), Inter-Vehicle Communication (IVC) have been a hot research direction in nearly a decade. To improve vehicle safety and cooperative systems, most of ITS applications need efficient and stable Vehicular Ad hoc Networks (VANETs) among vehicles and infrastructures, which can be set up by Geocast routing protocols. Some of...
The routing algorithms of DTN (Delay- and Disruption-Tolerant Networks) have not been efficient enough until now, which is one of the hot spots for DTN research. In this paper, aiming at fully using the knowledge inside the DTN environments both locally and globally, we propose a forecast method based on time-varying graph using time series analysis theory. By processing the history contact data with...
We investigate a computationally-efficient multipath routing scheme for survivable provisioning in Mixed-Line-Rate networks. Our approach exploits heterogeneity of multiple rates and guarantees that a specified fraction of the requested bandwidth survives any single-link failure.
Opportunistic routing in wireless networks has strong requirement with nodes' cooperation. But in most realistic networks, nodes perform in their own interests and refuse to forward packets for others when they belong to different organizations. The aim of this paper is to provide a fair incentive mechanism to encourage cooperation and achieve the energy efficient. We propose an auction incentive...
Delay is an important metric in Wireless-Optical Broadband Access Network (WOBAN). We introduce external buffer and design Delay-Differentiated Routing Algorithm (DDRA) for WOBAN. We show that delay performance of WOBAN can be improved by DDRA.
Aiming at improving the performance of relay transmission in multi-flow streaming overlay networks, a performance evaluation model to optimize the global weighted average latency was proposed. This model supports multiple senders and multiple receivers. A distributed heuristic allocation algorithm was proposed to optimize the transmission performance. In this algorithm, the bottleneck bandwidth shared...
A concentrator-based load balancing multi-path self routing switching fabric(LB-MPSR-C) was proposed recently, which was based on sorting concentrators, load-balanced and Birkhoff von-Neumann switching theory. This structure can achieve 100% throughput under admissible traffic pattern, its scalability for super large scale switching system and property of lowest hardware complexity have been deeply...
In a structured peer-to-peer (P2P) overlay network, the stability of the entire network will be greatly affected by simultaneous join-in and drop-out of large amount of nodes. Aiming at reducing the overhead of handling this activity, we propose a group-based hierarchically structured overlay network, GSON. GSON is also a structured P2P overlay network using distributed hash table (DHT). In GSON,...
