In this paper, we present a new distance and velocity assisted handoff decision algorithm (DVAH). By sampling the received power from base station (BS) continually and with the beforehand downloaded base station coverage radius and some propagation parameters, the mobile terminal (MT) can estimate the distance and the leaving velocity from surrounding BSs. By the assistance of the estimated distance...
With the rapidly developed wireless techniques, many wireless networks are deployed with widely varying characteristics. In order to fully utilize the complementary heterogeneous networks, the mobile terminal (MT) may handoff from one network to another by many subjective or objective reasons. The handoff process can be divided by three parts. Firstly, select the best network among different available...
