Abstract

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