METHOD AND SYSTEM FOR MANAGING INFORMATION STORAGE IN A DTN-BASED COMMUNICATION SYSTEM

摘要

There is provided a method of managing a node in a DTN-based communication system, the node being configured to store incoming messages in a main storage unit (15) in the form of objects and forward messages from the main storage unit (15) to other nodes of the network depending on forwarding conditions, one or more portions of the message being marked with a set of priority tags of given types, each tag being assigned a value, the method comprising managing the storage of messages in the main storage unit (15), by sorting the main storage unit (15) according to a main ordering rule being related to at least one priority tag, the node further comprising an auxiliary storage unit (52) comprising at least one auxiliary data structure (520), each data structure storing a logical reference to each object of the main storage unit (15), the method further comprising sorting each auxiliary data structure according to at least one auxiliary ordering rule related to at least one priority tag.
