Embodiment Construction

[0083] The present invention proposes a method for evaluating the reliability of a formation wireless communication network under multi-stage and multi-service, that is, a method for evaluating the reliability of a formation wireless communication network under a multi-stage and multi-service task profile. The flow chart is as follows: figure 1 shown.

[0084] Taking the wireless communication network of a certain ship formation as an example, the present invention will be further described in detail. The mission profile of the ship formation is as follows figure 2 shown; the business diagram is shown in image 3 shown; the packet generation rates of the four services are the same, λ (j) =5 / sec, j=1,2,3,4; the standard length of each service packet is the same, L=1024 bits; the packet processing rate of each node is the same, μ=15 / sec; bit error rate p 误码 = 0.001; packet loss rate p 丢包 = 0.01; the error rate threshold K = 0.005; the delay thresholds of the four services a...

Abstract

The invention provides a reliability evaluation method for a formation wireless communication network under a multi-stage and multi-service mission profile. The method comprises the following steps of1, computing a packet error rate of each service; 2, computing arrival and departure rates of an information packet on each node in each stage in the mission profile; 3, computing an effective arrival rate of the information packet on each node in each stage of the mission profile; 4, computing a parameter of time delay distribution on each node in each stage of the mission profile; 5, computingtransmission reliability of each service; and 6, computing mission reliability. According to the method, a purpose of carrying out quantitative analysis on the reliability level of the formation wireless communication network under the multi-stage and multi-service mission profile is achieved, a problem of reliability evaluation of the formation wireless communication network is solved, an analysis process is scientific and reasonable and is close to the actual situation, a reliability evaluation result has credibility, and meanwhile, the provided method is simple in computation and convenientfor engineering technicians to use, and has relatively high application value.

Description

technical field [0001] The present invention proposes a multi-stage multi-service formation wireless communication network reliability evaluation method, that is, a multi-stage, multi-service task profile reliability evaluation method for formation wireless communication networks, which is oriented to formation wireless communication network reliability analysis Considering the actual needs, communication characteristics and transmission mechanism, using technical means such as queuing theory and queuing network theory, the reliability evaluation problem of formation wireless communication network is solved when there are multi-stages and multi-services in the mission profile, which is applicable to Performance analysis and reliability evaluation of wireless communication networks and other related technical fields. Background technique [0002] A highly reliable formation wireless communication network is one of the basic elements to achieve combat effectiveness and ensure ...
