摘要：Delay tolerant network (DTN) is one of the key areas in wireless communication. Characteristics ofdelay tolerant network include intermittent connectivity, discontinuous connection from source to destination. It is anapproach to computer network architecture that seeks to address the technical issues of heterogeneous networkarchitecture which lack continuous network connection. This layer handles long delays, disconnectivity and high loserate due to disruption. Data will be stored in persistent storage on DTN device and it will be forwarded to other nodewhere the link is available. Main objective of this paper is to overcome the security attacks in delay tolerant networkand also to improve the link quality of the nodes. Since the nodes in the wireless sensor network will be subject todifferent attacks, different measures are taken to overcome the attacks and to reduce the delay. As a result the packetdelivery ratio is increased and hacking probability is reduced and network lifetime of node so that link quality will bemore
