22nd International Conference on Advanced Information Networking and Applications - Workshops (aina workshops 2008)
Distributed Data Aggregation in Multi-sink Sensor Networks Using a Graph Coloring Algorithm
March 25-March 28
ISBN: 978-0-7695-3096-3
In this paper, we propose an algorithm to minimize the multihop route from each sensor node to a sink node in wireless sensor networks with multiple sink nodes. In addition to solving the shortest path problem, the algorithm solves a time slot problem to support TDMA (time division multiple access) communication. TDMA is effective for avoiding packet collisions; however, the time slot allocation itself is a difficult problem to solve. We introduce a distributed coloring algorithm to solve it. After describing the algorithm, some experimental results proving its effectiveness are presented.
