In recent years, along with the increasing popularity of multi-hop wireless networks, there has been a growing demand in the coupling of these networks to external ones such as the Internet. As traffic destined for external networks increases, special attention is required not only in gateway selection, but also in optimized routing and scheduling in order to maximize the network performance. In this...
Wireless mesh network (WMN) is a promising solution for low cost last mile broadband Internet access. Different from Ad-hoc network which mainly concerns about mobility, the mesh nodes or mesh routers in WMN are connected via wireless links to form a multi-hop backbone infrastructure and improving throughput is their primary goal. Many technologies to build high throughput mesh networks have been...
Designing new IP routing architectures that are more amendable to optimization is a promising avenue for future research. With the proliferation of the Internet, popular Web services often suffer congestion and bottlenecks due to large demands made on their services. Such a scenario may cause unmanageable levels of traffic flow, resulting in many requests being lost. In the network approach, the network...
We studied a class of Service Overlay Network (SON) capacity allocation problem. By analyzing the problem with two different nonlinear optimization formulations, we show that the prices of offering service guarantees are closely related to a set of Lagrange multipliers. Moreover, if the Grade of service (GoS) constraints are not hard requirements, the network design resulting from the set of prices...
The rapid development of communication technology provides a enormous support for municipal mesh network. Nowadays many cities across the world have setup or prepare to setup wireless mesh networks (WMNs), includes Beijing city for its 2008 Olympic Games. However, Internet Gateway (IGW) placement, which is one of essential issues in a WMN design, has not been considered seriously in practice both...
We have currently reached a phase where big shifts in the network traffic might impose to rethink the design of current architectures, and where new technologies, being pushed into market, will act as enabler of such changes. Taking into account the current scenario and its likely evolution as well, in this paper we examine the case for multi-path routing within the metropolitan access network. Through...
Infrastructure wireless mesh networks promise a flexible and cost-effective means for providing last-mile delivery for broadband access, particularly in rural areas. Each customer forwards traffic between their neighbors and an Internet gateway, thus providing high coverage for little upfront investment. However, particularly during the early stages of deployment, seed nodes may be necessary to provide...
