摘要：Delay Tolerant Networks (DTNs) that are possibly composed of a vast number of devices such as smart phones of diversecapacities in terms of energy resources and buffer spaces. We introduces protocol which is a novel multi-copy routing protocol called SelfAdaptive Utility-based Routing Protocol (SAURP) for DTNs. SAURP has the ability to identify potential opportunities of forwardingmessages to their destinations via a novel utility function based mechanism, where a suite of environment parameters, such as wirelesschannel condition, nodal buffer occupancy, and encounter statistics, are jointly considered. Taking a considerably small number oftransmissions, it can reroute messages around nodes experiencing high buffer occupancy, wireless interference, and congestion. ThusSAURP utility function is proved to achieve optimal performance and it is also further analyzed via a stochastic modeling approach. Toverify the developed analytical model, extensive simulations are conducted and are compared the proposed SAURP and shown that SAURPcan perform all the counterpart multi-copy encounter-based routing protocols. These simulations are associated with the number of recentlyreported encounter-based routing approaches in terms of delivery ratio, delivery delay, and the number of transmissions required for eachmessage delivery
