Encryption algorithm and its applications in military communication;

This paper introduces four kinds of net-setting modes and characteristics of the wireless LAN,analyzes the advantages of the wireless LAN in the military communication,and elaborates the prospect of the application of the wireless LAN in the military realm.

The development of electronic countermeasure technology is a challenge to military communication, which calls for better robustness, real-time detection and covertness.

Study on the traffic modeling and simulation method of the military communication network;

The call traffic of military communication network is simulated by Monte Carlo simulation method,and the lost call is analyzed and compared between military communication network with alternate route and that without alternate route.

This paper introduces an efficient algorithm for the optimal edge-coloring of tree, which can solve the problem to optimize files transfer in tree-type military communication network like, and the algorithm makes sure that the sum of delay wastage of the edge-coloring tree is the smallest and receives the optimal project of files transfer by deducing reversely.
