一种基于路由表的无线传感器网络路由协议

路由协议是无线传感器网络研究的关键内容之一。提出了一种基于路由表的无线传感器网络路由协议SPBT。该路由协议采用路由表简化了数据传输过程，节省了能量；同时采用兼顾能量均衡和路径优化的策略建立数据传输路径，并且为了提高数据传输的可靠性采用了回溯策略。通过仿真，把该协议和基于协商机制的SPIN协议进行了比较，结果表明，SPBT协议具有良好的能量有效性、能量均衡性、较低的数据传输延迟和较高的数据投递率。

Table-based routing protocol in wireless sensor networks

Routing is one of the key problems in Wireless Sensor Network (WSN). A routing protocol based on routing table named SPBT (Sensor protocol based on routing table) was put forward. In the routing protocol, route tables were used to simplify the data transmission process to save energy, and the strategy for equilibrium of using energy and route optimization was used to establish routes. In order to improve the reliability of data transmission, the strategy of trace-back was adopted. In simulation, the table-based protocol was compared with the protocol SPIN. The results show that the protocol SPBT can use energy effectively with equilibrium of using energy and shortened delay.
