Neighbor Discovery in Wireless Network with Double-Face Phased Array Radar

As one of the important steps in the process of self-organization of wireless ad hoc networks, neighbor discovery has substantial influence on the network performance. Especially in the modern warfare environment, the time consumption of neighbor discovery is very important for holding the battlefield situation. In this paper, we address the problem of neighbor discovery in ad hoc network with double-face phased array radar. And we take advantage of double-face phased array radar to improve the efficiency of neighbor discovery. Unlike former researches on single beam directional antenna, double beam directional antenna is introduced to our system. However, the direction of the antenna has been limited to two exclusive ranges due to the structure of double-face phased array radar. Obviously, the performance of the system which is in half duplex working mode can be better than the same one using single beam antenna. Thus we compare our system with the one using single beam antenna which is in full duplex mode. The experiential results show that the performance of neighbor discovery using double-face phased array radar in half duplex working mode is about 5 times better than the one using single beam directional antenna in full duplex working mode with the same algorithm.
