Study on a novel location-based routing algorithm

A location-based grid routing (LBGR) algorithm is presented for aeronautical mobile Ad hoc networks (MANET) to resolve frequent reconstruction caused by rapid topology changes. By node position information, the LBGR algorithm employs a grid-constructed trajectory instead of node ID in forwarding packets. Based on the position relationship of nodes and downstream grids, each intermediate node infers the next hop to relay packets. Due to the use of location information, the algorithm can consume less overhead to acquire stable route between source node and destination node in the present of frequent and unpredictable topology changes. Simulation results show that, compared with GRID algorithm, the proposed algorithm can reduce route overhead and improve the network throughput.
