Abstract
To achieve low-latency, high-reliability data gathering in Wireless Sensor Network ( WSN ) , this paper formulates the joint problem of tree construction, link scheduling and power assignment for data gathering into an optimization problem, with the objective of minimizing data gathering latency. It divides the problem into two sub problems:construction of a low-latency data gathering tree, jointly link scheduling and power assignment for the data gathering tree. This paper proposes a polynomial heuristic algorithm for each sub problem and conducts extensive simulations. Simulation results show that the proposed algorithm achieves much lower data gathering latency than existing data gathering strategies while guaranteeing high reliability.关键词
