Efficient data gathering in sensor network is an important challenge. In this paper we address the problem of gathering sensed data to the sink of a sensor network minimizing the time to complete the process. We present optimal time data gathering algorithms for any type of topology of a sensor network. Our results improve on existing approximation algorithms. We approach the gathering problem by obtaining optimal solutions to the collision-free paths coloring problem.
