Abstract EN
Maximum weight independent set (MWIS) is a combinatorial optimization problem that naturally arises in many applications especially wireless networking.
This paper studies distributed approximation algorithms for finding MWIS in a general graph.
In the proposed algorithm, each node keeps exchanging messages with neighbors in which each message contains partial solutions of the MWIS optimization program.
A parameter H is introduced to achieve different tradeoff between approximation accuracy and space complexity.
Theoretical analysis shows that the proposed algorithm is guaranteed to converge to an approximate solution after finite iterations; specifically, the proposed algorithm is guaranteed to converge to the optimal solution with H = + ∞ .
Simulation results confirm the effectiveness of the proposed distributed algorithm in terms of weight sum, message size, and convergence performance.
