the mesh network has the characteristics of fast networking, flexibility, and controllable operation. The MAC layer protocol is the main factor determining the performance of the wireless mesh network. In the TDMA architecture, the MAC layer protocol mainly studies the slot allocation strategy. This paper mainly studies the current mainstream slot allocation protocols. Firstly, several strategies for time slot allocation are analyzed. Then, typical time slot allocation protocols are elaborated, and the advantages and disadvantages of the protocol are compared and analyzed. Thereafter, the key technology to the design of time slot allocation protocol is analyzed, and finally, the future development of the time slot allocation protocol is prospected.

Military professional education plays a key role in training high qualified military officer, the traditional education ideas has not been meet the requirement of the new military revolution. The problems such as traditional education values, role of teacher and students and teaching content system existing in the military professional education is concluded, the constructive teaching method is elaborated, and the approach to implement the constructive teaching in military professional education is discussed.

The transmit control protocol is used more and more widely as the development of mobile wireless network IP based and the need of high reliable data transmission in the unstable environment, but it has a poor performance due to the complex wireless channel and the variable network structure. Two TCP enhancement modules named unilateral TCP-accelerate module and parallel TCP-accelerate module were designed and imported to a test wireless network and a 3G system after analyzing the shortcoming of standard TCP and summarizing the popular TCP enhancement technologies. It proved that the modules designed which are easy to employ and flexible can improve the performance of TCP significant and can be used for reliable and burst transmission of broadband data in the mobile wireless network IP based.
