摘要
针对现有无线传感网络研究中缺乏统筹能量意识、安全机制等网络性能的问题,提出一种GPSR-EDM策略。该策略基于能量意识和安全机制,并在传统节能安全策略上增加了一种量化均衡的概念,致力于在节能和安全之间寻找平衡点,以达到信息传输最优化的目的。该策略以节点剩余能量和下一跳的距离为选择主路径的标准,同时加入监督节点形成监督路径(副路径),并在数据传输时引入选择唤醒和休眠机制。其中,主路径主要担负数据传输的任务,而副路径具有路由保护和数据传输的作用。仿真实验结果表明,该策略在统筹节能和安全等网络性能方面较GPSR有明显优势。
Aiming at the problem that many researches lack of the awareness of combing the energy conservation and security mechanism of Wireless Sensor Network （WSN） together into consideration, a strategy named GSPR-EDM is proposed. Based on energy awareness and security mechanism of WSN, this strategy puts forward a quantitative equilibrium concept on traditional energy security strategy, dedicates in searching for a balance between the two elements to achieve an optimization of information transmission. This strategy selects the residual energy of nodes and next jump distance as the standards to form the main path of route, while the monitoring nodes are added to form the supervising path（ vice path）. Meanwhile, the awaken and dor- mancy mechanism is employed when the data is transferred. In this strategy, the main path is designed for main transmission while the vice for route pro- tection and assistant transmission. The simulation results show that the strategy does better in the energy conservation and transmission security of WSN than GPSR.
