In this paper, we focus on the guarantee of inter-cell fairness in OFDM femtocell systems. To solve this problem, we formulate an optimization problem to maximize the summation of logarithmic cell capacity. Based on analytic results, we propose an enhanced modified iterative water-filling algorithm which improves inter-cell fairness compared to a modified iterative water-filling algorithm. The key...
We examine the issue of revenue adequacy in Financial Transmission Rights (FTR) Markets and address two questions: a) How should revenue shortfalls in FTR markets be assigned to market participants? and b) How can active participation by transmission owners in FTR markets incentivize transmission performance through incremental and long term investment? In particular we focus on the possibility of...
There has been considerable research interest in the area of traffic grooming for WDM mesh networks. The vast majority of the current work can be classified into one of two categories, either static grooming or dynamic grooming. In many situations, the individual traffic demands require bandwidth at certain predefined intervals, and resources allocated to nonoverlapping demands can be reused in time...
When you design networks that transport voice over packet, frame, or cell infrastructures, it is important to understand and account for the delay components in the network. If you account correctly for all potential delays, it ensures that overall network performance is acceptable. Delay guarantees are critical to real-time applications. To ensure the end-to-end delay guarantee of a flow, the previous...
MIMO two-way relay is a well known method for realizing highly efficient multi-hop relay networks. Previous works in MIMO two-way relay network have focused on an equidistant topology of the relay nodes. However such a topology rarely exists in a practical situation. In a non-equidistant topology, the end-to-end network capacity degrades severely due to the bottleneck link caused by uneven SNR. Furthermore,...
