40 GHz Indoor Networks Using Relay and Directional Antennas

Authors : Sami A. Ali and Mohammed Omer Salih

Abstract: With the growing of wireless communication, all available frequencies are reserved that leads to search for a new band of frequencies. Because it is very attractive for future communication, 40 GHz is selected. The reasons of selecting 40 GHz are very large bandwidth, free license and available of high data rate communication globally. Because of severe attenuation, the communication performance is significantly low. To enhance this point, relay with directional antennas are used. By using this combination, the utilized gain increases. Despite their advantages, there are many challenges with this method. From simulation, it can be found that adding relay to the network will enhance the loss path by 30%. Using directional antenna making the neighbor discovery more complicated. Elite Scanning Strategy (ESS) is proposed for pure directional communication. The proposed algorithm compared to Random Scanning Strategy (RSS) to approve its robustness in terms of neighbor’s discovery. The results show that ESS is performing better than RSS by 20% for the same network.
