【摘要】 针对基于测距的睡眠调度算法(RBSS)招募节点能耗大,导致网络过快失效问题,结合水环境无线传感网规则部署,采用分布式思想,提出一种基于测距的分布式招募调度算法(RBDRS).RBDRS算法采用分布式招募方法,将协作节点招募的任务转移到新招募的协作节点上,均衡网络能耗.招募节点通过测距招募距其最远的邻居节点作为协作节点,协作节点再依次为招募节点招募新的协作节点,直至无法招募到新的协作节点.仿真实验结果表明:与RBSS算法相比,RBDRS算法可均衡网络能耗,延长网络生命周期.更多还原

【Abstract】 Aiming at the problem of the range-based sleep scheduling algorithm(RBSS), which the energy consumption of recruit node is too large and affects the network life cycle, on the basis of the regular coverage model in water environment wireless sensor network, combined with the distributed thinking, a Range Based Distributed Recruit Scheduling(RBDRS) is proposed. The RBDRS algorithm adopts method of distributed recruitment, which transferrs recruited task of cooperating nodes to new-recruitment cooperative nodes in order to balance network energy consumption. Recruitment nodes recruit its farthest neighbor nodes as collaborative nodes by their distance,collaborative nodes recruit new collaborative nodes for recruitment nodes in turn until they are unable to recruit new collaborative nodes. Simulation results show that compared with the RBSS algorithm, the RBDRS algorithm can effectively balance network energy consumption and prolong the network lifetime.更多还原
