用matlab代码实现对SPMA协议的延迟，网络负载和吞吐量的性能分析

以下是一个简单的Matlab代码示例，用于模拟SPMA协议的延迟，网络负载和吞吐量的性能分析。该示例代码仅供参考，具体实现需要根据实际情况进行调整和优化。

% 模拟参数设置
num_packets = 1000;  % 数据包数量
packet_size = 100;   % 数据包大小
processing_time = 0.01; % 数据包处理时间
network_bandwidth = 10; % 网络带宽

% 初始化模拟结果
latency = zeros(num_packets, 1); % 延迟
throughput = zeros(num_packets, 1); % 吞吐量
network_load = zeros(num_packets, 1); % 网络负载

% 模拟数据包生成和传输
for i = 1:num_packets
    % 生成数据包
    packet = rand(packet_size, 1);
    
    % 计算传输时间和延迟
    transmission_time = packet_size / network_bandwidth;
    processing_start_time = i * processing_time;
    processing_end_time = processing_start_time + processing_time;
    transmission_start_time = processing_end_time;
    transmission_end_time = transmission_start_time + transmission_time;
    latency(i) = transmission_end_time - processing_start_time;
    
    % 计算网络负载和吞吐量
    network_load(i) = packet_size / transmission_time;
    throughput(i) = i * packet_size / transmission_end_time;
end

% 计算平均延迟，平均网络负载和平均吞吐量
avg_latency = mean(latency);
avg_network_load = mean(network_load);
avg_throughput = mean(throughput);

% 输出结果
disp(['平均延迟：', num2str(avg_latency), 's']);
disp(['平均网络负载：', num2str(avg_network_load), 'bps']);
disp(['平均吞吐量：', num2str(avg_throughput), 'bps']);
