An effective low-delay routing algorithm in opportunistic networks

To address the problems of large transmission delay and low success rate in DBGRS (Direction Based Geographic Routing Scheme), we propose an novel routing algorithm which optimizes the process of data forwarding and makes full use of the information in the neighbor table to achieve the goal of reducing the transmission delay and increasing the success rate. Theoretical analysis and simulation results show that our proposed algorithm outperforms DBGRS in terms of average delay, number of packets transmission, and the success rate of packets transmission.
