Throughput consideration for location-aware handoff in mobile data networks

Location aware handoff algorithms have a much better performance than traditional algorithms in terms of the number of handoffs and handoff delay (crossover point). As they do not pay attention to the received signal strength (RSS), it is not clear if they also maintain the best throughput in the case of wireless data networks. We evaluate the tradeoffs between unnecessary handoffs, handoff delay and system throughput. The results indicate that, with location-aware handoff algorithms, the throughput is also higher than the throughput in the case of using traditional RSS-based algorithms.
