Maximum Independent Set of Links under Physical Interference Model
This paper addresses the following optimization problem in a plane multihop wireless networks under the physical interference model: From a given a set of communication links whose senders transmit at a fixed uniform power level, select a maximum set of independent links. This problem is known to be NP-hard. The existing approximation algorithms which were claimed to have constant approximation...
متن کاملMLLS: Minimum Length Link Scheduling Under Physical Interference Model
We study a fundamental problem called Minimum Length Link Scheduling (MLS) which is crucial to the efficient operations of wireless networks. Given a set of communication links of arbitrary length spread and assume each link has one unit of traffic demand in wireless networks, the problem MLS seeks a schedule for all links (to satisfy all demands) of minimum number of time-slots such that the l...
متن کاملMaximum Weighted Independent Set of Links under Physical Interference Model
Interference-aware scheduling for wireless communications is crucial to improve the network throughput. In this paper, we study the problem of Maximum Weighted Independent Set of Links (MWISL) under the physical interference model in wireless networks. Given a set of communication links distributed in a two-dimensional Euclidean plane, assume each link is associated with a positive weight which...
متن کاملSpectrum Auctions
Auctions have emerged as the primary means of assigning spectrum licenses to companies wishing to provide wireless communication services. Since July 1994, the Federal Communications Commission (FCC) has conducted 33 spectrum auctions, assigning thousands of licenses to hundreds of firms. Countries throughout the world are conducting similar auctions. I review the current state of spectrum auct...
متن کاملSpectrum Auctions
Most developed countries allocate radio spectrum by auction. The Simultaneous Ascending Auction (SAA) has proven to work well for this application. Recently, new designs that allow package bidding have been proposed. These designs have only been tried in the past few years. We first provide some historical background regarding the allocation of spectrum, describe the use of the SAA design and i...
