Analysis of path losses and isolation in 60 GHz networks and design of intelligent neighbor scanning

60 GHz technology is highly attractive because of its significant usage in the future communication systems for higher bandwidth applications. 60 GHz technology is providing license free spectrum in the range of 59-64 GHz, immunity to co-channel interference, better spatial reuse, higher security advantages and higher data rate up to about 4 Gbps. The path losses are higher in 60 GHz technology as compared to any lower GHz technology with same specifications because the propagation loss increases with the square of the carrier frequency and it is the notable challenge in implementing 60 GHz technology. In home environments, different type of objects and bodies may interrupt the line of sight propagation path. Interruption of 60 GHz connection can be kept up by bringing scattering from the surfaces into consideration but unfortunately it takes into account the additional scattering losses. In this project, a relay based analytical model will be implemented. This model will brief about the gains of relays placed in 60 GHz networks. This gain will be calculated in terms of path loss by deploying nodes randomly. These nodes will be made to communicate directly and via relay. Afterwards, quality of links in terms of received power will be determined and compared. Deployment of directional antennas is highly risky because of severe attenuation, deafness and delays in 60 GHz networks. An intelligent stochastic model of neighbor scanning will be designed. Comparisons will be made on the account of link discovery, probability of acting as receiver or transmitter, isolating capability with the conventional neighbor scanning design. Simulations and verification of analytical model will be carried out on Matlab.
