Mobility is the distinct feature of wireless mobile cellular system. Usually,
continuous services is achieved by supporting handoff which is the transfer of an
ongoing call from the current cell to the next adjacent cell as the mobile moves
through the coverage area. usually handoff calls are given higher priority than new
calls since it has a significant impact on the network performance. Simulation study
of the relative signal strength with hysteresis and threshold (RSS-HT) algorithm for
varying hysteresis and threshold are studies to evaluate the mean number of cell
handoffs, mean number of wrong cell handoffs and expected average signal strength.
Keywords- Cellular network, signal strength, handoff schemes.
