Abstract
In the future heterogeneous integrated wireless network environment, delay limited network has the characteristics of distributed self-organization, multi hop transmission, delay tolerance and intermittent link connection. Although it has great application value in many scenarios, it still needs to provide certain QoS guarantee according to the business requirements. Therefore, how to effectively transmit information to meet the needs of different services in terms of transmission rate and delay is one of the key issues in the research of path allocation in delay constrained networks. In this paper, a path allocation method based on service priority is proposed. Network nodes use local information to evaluate the network state and calculate the initial service priority, and then select relay nodes according to congestion degree and encounter probability. Simulation results show that the algorithm improves the quality of service of high priority services in congestion, and provides high performance services for low priority services when the network resources are sufficient.
