This paper solves the joint power control and SIR assignment problem through distributed algorithms in uplink of multi-cellular wireless networks. The 1993 Foschini-Miljanic can attain a given fixed feasible target. In data networks, however, needs to be jointly optimized with transmit powers vast research literature since mid-1990s, solutions this optimization are either but suboptimal, or optimal centralized. For convex formulations problem, we report algorithm. main issue that has been...

Pricing content-providers for connectivity to end- users and setting connection parameters based on the price is an evolving model Internet. The implications are heavily debated in telecom policy circles, some advocates of "Network Neutrality" have opposed differentiation connectivity. However, pricing content providers can possibly subsidize end-user's cost connectivity, consequent increase end-user demand benefit ISPs providers. This paper provides a framework quantify precise trade-off...

A common assumption behind most of the recent research on network rate allocation is that traffic flows are elastic, which means their utility functions concave and continuous there no hard limit allocated to each flow. These critical assumptions lead tractability analytic models for based maximization, but also applicability resulting protocols.

In this paper, we study the revenue sharing and rate allocation for Internet Service Providers (ISPs) that jointly provide network connectivity between content providers end-users. Without colluding, each ISP may selfishly set a high transit-price to cover its cost maximize own profit, which inevitably results in loss social profit. We model noncooperative interaction an "eyeball" "content" as Stackelberg game quantify resulting To recover profit loss, propose contract ISPs by modeling them...

Usage-based pricing has been recognized as a network congestion management tool. Internet Service Providers (ISPs), however, have limited ability to set time-adaptive usage-price manage arising from time-varying consumer utility for data. To achieve the maximum revenue, ISP can its time-invariant low enough aggressively encourage consumer's traffic demand. The downside is that drop excessive demand through (i.e., packet dropping), which may degrade Quality of (QoS) traffic. Alternatively,...

Flat fading approximation assumes that the system bandwidth is small compared to coherence bandwidth. An upper bound derived for an error involved in flat thereby giving us a measure of degradation. The found vary as square ratio.

The problem of channel estimation for a frequency hopping system is considered. Under discrete multipath fading model, the path gains and delays are estimated separately. By exploiting fixed (but unknown) patterns in data packet, delay formulated an ESPRIT-like format by identifying multiple rotational invariance structures received data. Since ESPRIT limited to exploitation single invariance, previously proposed SPECC algorithm employed estimation. Performance results based on simulations presented.
