Opportunistic network environment-oriented multi-object routing decision making system

Abstract

The invention provides an opportunistic network environment-oriented multi-object routing decision making system, which comprises an environment setting module (1), an ant-colony-based dynamic topological path searching module (2), a linear-distribution-method-based path evaluation module (3) and a route selection module (4). The decision making system can satisfy different needs of a decision maker or upper-layer application in routing objects and receive the preference information of the decision maker or the upper-layer application over the routing objects as routing guiding rules, adopts the combination of an improved ant colony algorithm and a linear distribution method as a main algorithm, performs the three main activities of responsibility definition, scheme planning and scheme evaluation, and can realize multi-object optimization to improve overall routing performance and better satisfy routing needs.

Description

technical field [0001] The invention belongs to the field of computer network communication, in particular to a multi-objective routing decision-making system oriented to an opportunistic network environment. Background technique [0002] The reason for the challenge network is that it violates certain assumptions of the TCP / IP protocol, including: [0003] 1) There must be a continuous end-to-end path between the sending and receiving nodes; [0004] 2) The RTT between any pair of transceiver nodes is small and relatively consistent; [0005] 3) The bit error rate and packet loss rate of the communication link are low, and the application program does not need to consider the communication performance and so on. [0006] An opportunistic network is a challenge network composed of mobile peer-to-peer communication nodes, nodes with message storage capabilities, and random contacts between nodes. Due to the difference between opportunistic networks and traditional Internet...

Problems solved by technology

However, in the field of opportunistic network routing, no relevant researchers have proposed a routing decision-making technology that considers multiple routing targets to meet the needs of decision makers or upper-layer applications for routing targets.

[0007] In the fields of Internet, WSNs, and AdHoc networks, there are corresponding studies on multi-objective routing, but due to the differences in the characteristics of these network environments and opportunistic network environments, their research results cannot be well applied to opportunistic networks.
