چکیده

We present an approximation algorithm for wireless link scheduling under the physical SINR interference model. In the link scheduling problem, it is given a set of n links in a metric space, each of which is a sender–receiver pair, and the objective is to schedule the links using the minimum amount of time. We focus on a variant of this fundamental problem where the power is fixed, i.e., the power assignment of links is given as part of the input. Specifically, we consider an important category of power assignments called length-monotone sublinear power assignment, which includes the widely studied uniform, mean and linear power assignments. We present a distributed B Yuexuan Wang [email protected] Dongxiao Yu [email protected] Qiangsheng Hua [email protected] Jiguo Yu [email protected] Francis C. M.

Wireless Network Stability in the SINR Model

We study link scheduling in wireless networks under stochastic arrival processes of packets, and give an algorithm that achieves stability in the physical (SINR) interference model. The efficiency of such an algorithm is the fraction of the maximum feasible traffic that the algorithm can handle without queues growing indefinitely. Our algorithm achieves two important goals: (i) efficiency is in...

A Fast Distributed Approximation Algorithm for Minimum Spanning Trees in the SINR Model

A fundamental problem in wireless networks is the minimum spanning tree (MST) problem: given a set V of wireless nodes, compute a spanning tree T , so that the total cost of T is minimized. In recent years, there has been a lot of interest in the physical interference model based on SINR constraints. Distributed algorithms are especially challenging in the SINR model, because of the non-localit...

Joint Link Scheduling and Topology Control for Wireless Sensor Networks with SINR Constraints

This chapter studies the joint link scheduling and topology control problems in wireless sensor networks. Given arbitrarily located sensor nodes on a plane, the task is to schedule all the wireless links (each representing a wireless transmission) between adjacent sensors using a minimum number of timeslots. There are two requirements for these problems: first, all the links must satisfy a cert...

Exploring the Design Space of Greedy Link Scheduling Algorithms for Wireless Multihop Networks

It is known that using a spatial TDMA (STDMA) access scheme can increase the capacity of a wireless network over CSMA/CD access scheme. Modern wireless devices are capable of transmitting at different data rates depending on the current network condition. However, little attention has been paid to how best is to use the multiple data rates capability. In this report, we focus on greedy link sch...
