The ultimate success of the Wireless Mesh Network paradigm (WMN) in large scale deployments depends on the ability to test it in real world scenarios. A typical application scenario which is worth to be investigated in such a context is peer-to-peer traffic management. The creation of large scale testbeds for evaluating wireless mesh technologies and protocols, and for testing their ability to support...
The paper presents a concept of the peer-to-peer related traffic optimization. The mechanism is based on the Oracle idea, where a peer is informed on closely located P2P nodes suggesting connection to them. The Oracle gains the relevant information on the basis of BGP databases, where the important extension is related to using a cooperation mechanism between different operators' domains.
In recent years peer-to-peer (P2P) systems gain much attention. Growing popularity in P2P based protocol implementations for file sharing purposes caused that the P2P traffic exceeds Web traffic, once of the dominant traffic on the Internet. In fact of that, the use of P2P systems introduce many new problems related to traffic engineering or network optimization. In accordance to our previous works...
This paper presents a novel cross-layer design for joint power and end-to-end rate control optimization in DS-CDMA wireless networks, along with a detailed implementation and evaluation in the network simulator ns-2. Starting with a network utility maximization formulation of the problem, we derive distributed power control, transport rate and queue management schemes that jointly achieve the optimal...
We present an asynchronous wakeup policy for wireless sensor networks that exploits the available path diversity for maximizing the expected network lifetime. We assume a random traffic generation model such that the rate is constant in time. Each node is assumed to have a set of forwarding neighbors, any of which may be used for forwarding its traffic to the sink. A node having data packet to send,...
Link-state routing with hop-by-hop forwarding is widely used in the Internet today. The current versions of these protocols, like OSPF, split traffic evenly over shortest paths based on link weights. However, optimizing the link weights for OSPF to the offered traffic is an NP-hard problem, and even the best setting of the weights can deviate significantly from an optimal distribution of the traffic...
In this paper we present a partially asynchronous, fully distributed flow-based access scheme for slotted-time protocols, that guarantees proportional-fairness in ad hoc wireless networks. This problem of providing fairness in wireless networks is considered in the framework of non-linear optimization. We say a medium access control algorithm is proportionally fair with respect to individual end-to-end...
