Tradeoffs between Handover Performance and Coverage Range of Relay Stations in Multihop Cellular Networks
Relay station is a recent approach for multihop cellular networks to increase a signal quality as well as support a high speed data transmission. The coverage range of relay station is determined by its transmit power and level of handover between relay station and its base station. This coverage range directly influences to handover performance. If number of handover increases, the expense of signaling overheads and capacity deficiency will be increased. In this paper, the investigation into number of handover related to coverage range of relay station is presented. In addition, various handover scenarios in cellular networks are also examined. The results indicate that the tradeoff between number of handover scenarios and coverage range depends on type of handover scenarios.
