Bandwidth_Allocation_and_Service_Handoff_in_IEEE80
说明: 本文针对无线网络中的多种服务类型,对
无线网络的带宽分配和接入方式进行分析,深入分析了不同类型的网络带宽资源
分配和调度算法在运行过程中对网络性能的影响。同时,本文也针对切换服务对
无线网络带宽分配的影响情况进行了分析,对切换服务的路由重建方式进行优
化,提高网络的实际运行性能。(This paper has
analyzed the bandwidth allocating process of wireless network with different services
types and compared the performance of different bandwidth allocating schemes. At
the same time, this paper also gives an eye to the impact brought by handoff process.
We have optimized the handoff rerouting process to improve the performance when
the handoff process tack place. The main work and contributions are presented in the
following aspects.)

% 文件名:randlsbget.m
% 程序员:余波
% 编写时间:2007.6.25
% 函数功能: 本函数将完成提取隐秘于上的秘密信息
% 输入格式举例:result=( scover.jpg ,56, secret.txt ,2001)
% 参数说明:
% output是信息隐藏后的图象
% len_total是秘密信息的长度
% goalfile是提取出的秘密信息文件
% key是随机间隔函数的密钥
% result是提取的信息
function result=randlsbget(output,len_total,goalfile,key)
ste_cover=imread(output)
ste_cover=double(ste_cover)
% 判断嵌入信息量是否过大
[m,n]=size(ste_cover)
frr=fopen(goalfile, a )
% p作为信息嵌入位计数器将信息序列写回文本文件
p=1
% 调用随机间隔函数选取像素点
[row,col]=randinterval(ste_cover,len_toal,key)
for i=:len_toal
if bitand(ste_cover(row(i),col(i)),1)==1
fwrite(frr,1, bit1 )
