Abstract
Wireless indoor networks employing Radio over Fiber technique combining 60GHz wireless
networks with wired networks is a new solution to provide high definition in-home multimedia applications.
About 5 Gbps is available around 60GHz band. In 60GHz band each antenna can cover
a small space such as a single room in a building. Thus more antennas are needed to cover the
whole building. This leads to frequent handoffs. In addition, the overlapping between two adjacent
cells is normally small; therefore a handoff should be completely done in a relatively shorter time
compared to cellular networks. Since there are many research results and commercial systems for
wireless indoor positioning, predicting the direction of the movement of a user is very easy. This
paper proposes the direction assisted handoff algorithm. The simulation results show that the proposed
handoff algorithm can reduce the total number of handoffs while increasing the percentage of
successful handoffs.
