Abstract:

Based on the localization technology and adjustable grid to improve the existing routing algorithm, we proposed an improved routing algorithm based on adjustable grid and crossregion transmission, and solved the problem of energy  imbalance and high energy consumption of perimeter stateless
 greedy routing algorithm in wireless sensor network. Using a localization algorithm of relative position of nodes, adjustable grid, greedy algorithm and right
hand rule, the algorithm established routing path of regional level  coarseness, and the network used different methods to transmit data according to the density of sensor nodes in different regions. Simulation experiment results show that the improved algorithm reduces the energy consumption of network  and extends the lifecycle of network.
