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.
