Abstract

We analyzed the handoff performance of a multihop-based wireless LAN that uses access points (APs) for communication. When a mobile terminal is not able to communicate with any APs, it uses other mobile terminals as terminal repeaters (TRs). The handoff criteria are based on absolute and relative signal strengths. The performance criteria are the average number of handoffs and the average handoff delay. We investigate the relation between the handoff criteria and the performance criteria when both the mobile terminal and the terminal repeaters are moving. Numerical results are presented to show that the average handoff delay decreases but the average number of handoffs increases as the speed of the TRs is increased.
