Ren Xiu-l · Jilin Normal University Journal · 2015
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.
