A message transmission system for opportunistic networks

Abstract

An opportunistic network is a type of challenged networks, which has not any stable end-to-end delivery path between source nodes and destination nodes, and the messages are transmitted by the “store-carry-and-forward” paradigm when message-carrying nodes encounter other nodes until they reach the destination nodes. In this paper, we design a message transmission system-BlueChat-for opportunistic networks by Bluetooth protocol, which includes a routing protocol and a message queue management strategy. Performance of this system is tested and it could meet the message transmission needs of opportunistic networks.
