时延敏感传感器网络中分布式动态资源管理研究
Study on distributed and dynamic resource management for delay-sensitive sensor network
摘要
Abstract
The delay-aware dynamic resource management problem was investigated in sensor network, with a focus on resource allocation among the sensors and power control along the time. By taking account of average delay requirements and power constraints, the considered problem was formulated into a stochastic optimization problem. Inspired by Lya-punov optimization theory, the intractable stochastic optimization problem was transformed into a tractable deterministic optimization problem, which was a mixed-integer resource management problem. By exploiting the specific problem structure, the mixed-integer resource management problem was equivalently transformed into a single variable problem, and the cooperative distributed method was present to effectively solve it with guaranteed global optimality. Finally, a dynamic resource management algorithm was proposed to solve the original stochastic optimization problem. Simulation results show the performance of the proposed dynamic algorithm and reveal that there exists a fundamental tradeoff be-tween delay requirements and power consumption.关键词
