Welcome to ICNP 2010, the eighteenth IEEE International Conference on Network Protocols, and welcome to Kyoto, Japan! ICNP is the premier conference covering all aspects of network protocols, including design, analysis, specification, verification, implementation and performance. This is our third organization of ICNP in Japan. In 1995, 15 years ago, we first organized ICNP at Tokyo. Tokyo is the...
Welcome to IEEE ICNP 2010, the Eighteenth International Conference on Network Protocols in Kyoto, Japan! Continuing the tradition of being the premier conferences on network protocols, we have an exciting program with papers, posters and a panel, representing the best of today's research. We are delighted to have two keynote speakers this year: Professor P. R. Kumar (University of Illinois at Urbana-Champaign,...
In this paper, we study the problem of routing in networks with max-min fair congestion control at the link level. The goal of each user is to maximize its own bandwidth by selecting its path. The problem is formulated as a non-cooperative game. We first prove the existence of Nash Equilibria. This is important, because at a Nash Equilibrium (NE), no user has the incentive to change its routing strategy...
Physical impairments, such as noise and signal distortions, negatively affect the quality of information transfer in optical networks. The effect of physical impairments predominantly augments with distance and bit rate of the signal to the point that it becomes detrimental to the information transfer. To reverse the effect of physical impairments, the signal needs to be regenerated at nodes that...
Current network infrastructures exhibit poor power efficiency, running network devices at full capacity all the time regardless of the traffic demand and distribution over the network. Most research on router power management are at component level or link level, treating routers as isolated devices. A complementary approach is to facilitate power management at network level by routing traffic through...
New generations of video, voice, high-performance computing and social networking applications have continuously driven the development of novel routing technologies for higher packet forwarding speeds to meet the future Internet demand. One of the fundamental design issues for core routers is fast routing table lookup, which is a key problem at the network layer of the Internet protocol suite. It...
Geographic routing is a promising approach for point-to-point routing in wireless sensor networks, but it requires the availability of geographic coordinates. Location devices like GPS do not work indoors and they are often not cost-effective for ubiquitous deployment on a large scale. While it is possible to manually configure coordinates for small sensor networks, it is infeasible to do the same...
Interference modeling is crucial for the performance of numerous WSN protocols such as congestion control, link/channel scheduling, and reliable routing. In particular, understanding and mitigating interference becomes increasingly important for Wireless Sensor Networks (WSNs) as they are being deployed for many data-intensive applications such as structural health monitoring. However, previous works...
Accurate localization is crucial for wireless ad-hoc and sensor networks. Among the localization schemes, component-based approaches specialize in localization performance, which can properly conquer network sparseness and anchor sparseness. However, such design is sensitive to measurement errors. Existing robust localization methods focus on eliminating the positioning error of a single node. Indeed,...
As an alternative to radio-frequency (RF) communications, optical wireless communications (OWC) can support high data rates and low power operations while providing good jamming resistance. Our focus in this paper is on deep ultraviolet (UV) outdoor communications (UVOC) where solar blind and non-line-of-sight operations are attractive. Light beams from UV LED arrays serve as information carriers...
We describe grant-to-send, a novel collision avoidance algorithm for wireless mesh networks. Rather than announce packets it intends to send, a node using grant-to-send announces packets it expects to hear others send. We present evidence that inverting collision avoidance in this way greatly improves wireless mesh performance. Evaluating four protocols from 802.11 meshes and 802.15.4 sensor networks,...
Network coding has been proposed as an alternative to the conventional store-and-forward routing paradigm for data delivery in networks. When deployed in a multi-rate wireless network, network coding has to interact with rate adaptation. When multicasting packets (a requirement of network coding) in a multi-rate IEEE 802.11 wireless network, one must use care when selecting the transmission rate to...
There are several situations in which it would be advantageous to allow route preferences to be dependent on which neighbor is to receive the route. This idea could be realised in many possible ways and could interact differently with other elements of route choice, such as filtering: not all of these will have the property that a unique routing solution can always be found. We develop an algebraic...
Compliance with the Gao-Rexford conditions [1] is perhaps the most realistic explanation of Internet routing stability, although BGP is renowned to be prone to oscillations. Informally, the Gao-Rexford conditions assume that (i) the business relationships between Internet Service Providers (ISPs) yield a hierarchy, (ii) each ISP behaves in a rational way, i.e., it does not offer transit to other ISPs...
One of the most common provider provisioned VPN technologies uses MPLS as a data plane for customer flow isolation and BGP as a control plane for routing between VPN sites. From a data plane perspective, such networks can provision hundreds of thousands of VPN sites. However, the BGP control plane is prone to scalability concerns. Some BGP routers in VPN backbones must handle routes for all the VPN...
IP prefix hijacking is one of the top security threats targeting today's Internet routing protocol. Several schemes have been proposed to either detect or mitigate prefix hijacking events. However, none of these approaches is adopted and deployed on a large-scale on the Internet for reasons such as scalability, economical practicality, or unrealistic assumptions about the collaborations among ISPs...
