针对无线传感器网络能量消耗大和网络生存时间短的问题，提出了一种具有引导距离和位置意识的GEAR路由优化协议（ GLGEAR）。该协议在选择下一跳节点时，引入了引导距离这个概念，改进了估计代价计算公式，使选路更加优化，从而减少数据传输时的能量消耗；为了找到离目标区域更近的邻居节点，设计了新的节点选择方法，降低了计算的复杂性，缩短了路径的建立时间。同时，该协议给出了路由空洞和数据传输失败时的解决策略，使GLGEAR协议具有更好的可靠性。仿真结果表明，该协议在网络生存时间，路径生成能量消耗，数据传输成功率等方面的性能表现优于TO-GEAR等协议。

Focus on the problems of big energy consumption and short survival time of the network,GEAR routing optimization protocol( GLGEAR)was proposed based on Guiding Distance and Location Aware in wireless sensor network. When GLGEAR select the next sensor node,the concept of guiding distance was introduced to modify the formula of estimated cost for routing more optimized,so that it could reduce the energy consumption during data transmission. For finding the suitable sensor node which was closer to the target area,GLGEAR designed a new node selection method. The method could reduce the computational complexity and shorten the path setup time. At the same time GLGEAR also designed strategies to solve the problems of routing holes and the failure of data transmission. Simulation results indicated that GLGEAR is more effective and available than TO-GEAR in network lifetime,energy consumption of path setup,and success rate of data transmission.
