The Delay Tolerant Network is an Emerging Disruption Tolerant Network, which usually deals with
communications in extreme challenged environments. There is not any end to end path between source and destination
means there may not any direct path exist between them even if they communicate with each other because of mobi lity of
nodes and store-carry and forward scheme. Many routing protocols used in DTNs which follow Store, Carry and
Forward paradigm and transfer data among disconnected network. To improve delivery ratio, Average delay and
overhead ratio in DTNs, this paper used Probability based Spray & Wait Protocol. This paper calculates the probability
of the next relay node and utilizes the information about quality of node and remaining power to allocate the number of
copies to the next relay node in the spray phase.
