摘要:Multi hop cellular networks (MCNs) use multiple low-power transmitters for high throughput andcoverage of large area in a network. The network consists of Base stations (BSs) and Relay Stations (RSs) placed insidethe center and edge of the network that could transmit the frequency simultaneously. The network performance can beaffected by the mobile stations which lead to co channel interference (CCI) near the coverage boundary of the cell. Thetraffic quality and the quality of service (QOS) can hardly be guaranteed due to the unbalanced user distribution. Thestatic method is used which divides the network into a tri-sector network according to the frequency reuse scheme thatworks with the downlink of OFDMA-based specification. The throughput increases by accommodating more users inthe coverage area in a MCNs. Interference in the cell edge is avoided by implementing the avoidance algorithms wherethe base stations are placed in the centre of the cell and in tri-sector of the network.
