An Approximation Algorithm for the Wireless Gathering Problem
The Wireless Gathering Problem is to find an interference-free schedule for data gathering in a wireless network in minimum time. We present a 4-approximate polynomial-time on-line algorithm for this NP-hard problem. We show that no shortest path following algorithm can have approximation ratio better than 4.

برد عددی ماتریس مربعی a را با w(a) نشان داده و به این صورت تعریف می کنیم w(a)={x8ax:x ?s1} ، که در آن s1 گوی واحد است. در سال 2009، راسل کاردن مساله برد عددی معکوس را به این صورت مطرح کرده است : برای نقطه z?w(a)، بردار x?s1 را به گونه ای می یابیم که z=x*ax، در این پایان نامه ، الگوریتمی برای حل مساله برد عددی معکوس ارانه می دهیم.
15 صفحه اولThe Distributed Wireless Gathering Problem
We address the problem of data gathering in a wireless network using multihop communication; our main goal is the analysis of simple algorithms suitable for implementation in realistic scenarios. We study the performance of distributed algorithms, which do not use any form of local coordination, and we focus on the objective of minimizing average flow times of data packets. We prove a lower bou...
متن کاملAn Approximation Algorithm For Point Guard Problem
In 1973, Victor Klee posed the following question: How many guards are necessary, and how many are sufficient to patrol the paintings and works of art in an art gallery with n walls? This resulted in many subsequent researches so that the various versions of the art gallery problem were posed. Most of the versions posed are NP-hard, so designing approximation algorithms becomes important. The b...
متن کاملAn Approximation Algorithm for Alphabet Indexing Problem
Alphabet Indexing is the problem to nd a mapping f : ! f1; : : : ;Kg for alphabet , positive integer K and a pair of disjoint sets of strings P;Q such that f transforms no two strings from P and Q into identical ones. Although Alphabet Indexing problem is NP-complete, we de ne a combinatorial optimization problem, Max K-Indexing, and propose a simple greedy algorithm for this problem. Then we s...
