基于无线传感器网络的道路管理系统

Roads Managing System Based On Wireless Sensor Networks

无线传感器网络具有布线成本低、监测精度高、容错性好、可远程监控等众多优点,在环境监测等领域有着广阔的应用前景。基于当前对无线传感器网络下的道路管理系统问题的迫切需求,研究传感器节点覆盖问题来实现完全监测覆盖并降低网络成本.结合实际应用,基于树形路由算法提出新的节点间路由算法来延长网络寿命.并用OMNET++验证得到了在物理条件下难以实验的实例模型的性能参数。

Wireless sensor networks have many advantages such as low-cost routing, monitoring of high accuracy, good fault-tolerant and remote monitoring. It is widely used in monitoring of environment. Aiming at the urgency of roads managing system based on wireless sensor networks, sensors coverage is studied to achieve complete coverage of. monitoring and reduces cost of application. Combined with practical application, a new routing algorithm of inter-nodes is proposed to prolong life based on tree routing algo- rithm. Then by OMNET＋＋, some important parameters of performance are acquired, which are difficult to be implemented in actual physical environment.
