主　　题：Routing algorithms 

摘      要：Epidemic-based routing algorithms have some redundancy in the process of packets exchange and sensing neighbor. To address this problem, a low-delay routing algorithm of Delay-Tolerated Network based on packet exchange, PEA (Packet exchange algorithm), was proposed in this *** algorithm firstly sent data packet when nodes sensed encountered node, broadcast SV packets to speed sensing neighbor and decrease end-to-end delay. Theoretical analysis and simulation results show that PEA outperforms the classical Epidemic routing algorithm in terms of end-to-end delay, the total time of data delivery.
