GM(1_1)
GM(1,1)模型1-4
1：GM(1,1)模拟模型，在matlab中的输入方法为gm1（x），x指要模拟的序列。
2：GM(1,1)预测模型，在matlab中的输入方法为gm2（x，K），x指要模拟的序列，K指从以后序列第一个数据算起的第k个待预测数据。
3：GM(1,1)群模拟模型，在matlab中的输入方法为gm3（x），x指要模拟的序列。
4：GM(1,1)群预测模型，在matlab中的输入方法为gm4（x，K），x指要模拟的序列，K指从以后序列第一个数据算起的第k个待预测数据。
gm4对序列趋势比较好的数据预测效果较好，对上下变动的数据，特别是后4个数据趋势跟前面的数据相反的，预测效果很差。
gm2对上下变动的数据，预测效果比gm4好，但对趋势较好的数据，预测精度没有gm4高。
gm3比gm1模拟精度要高。
可以以x=[1 3 5 7 9 11 13 15]进行实验。x输入默认行向量。
所有程序在matlab6.0上调试通过。(GM (1,1) 1-4 1 : GM (1,1) simulation model Matlab in the input method for gm1 (x), x entail simulation sequence. 2 : GM (1,1) model, in the Matlab input method for gm2 (x, K), x entail simulated sequence, from the K refers to the first series after a run of data k pending forecast data. 3 : GM (1,1)- simulation model, in the Matlab input method for gm3 (x), x entail simulation sequence. 4 : GM (1,1)- forecasting model, in the Matlab input method for gm4 (x, K), x entail simulated sequence, from the K refers to the first series after a run of data k pending forecast data. Gm4 right sequence relatively good trend data predicted better results, the next change in the data, especially after four data with the previous trend data contrary, predict poor.

Wireless Sensor Networks (WSNs) are comprised of thousands of sensor nodes, with restricted energy, that cooperate
to accomplish a sensing task. Various routing Protocols are designed for transmission in WSNs. In this
paper, we proposed a hybrid routing protocol: Zonal-Stable Election Protocol (Z-SEP) for heterogeneous WSNs.
In this protocol, some nodes transmit data directly to base station while some use clustering technique to send
data to base station as in SEP. We implemented Z-SEP and compared it with traditional Low Energy adaptive
clustering hierarchy (LEACH) and SEP. Simulation results showed that Z-SEP enhanced the stability period
and throughput than existing protocols like LEACH and SEP.
