• In this paper, we propose a new channel allocation scheme, which is designed to efficiently carry out handoffs in wireless networks. Our scheme is based on conventional hand-off methods, which include the channel reservation, carrying and sub-rating methods to assign channels for handoffs. First, we re-serve a number of channels only for handoffs. Second, if there is no available channel in the next cell during handoff, the mobile station is allowed to carry a movable channel into the next cell. Finally, in order to avoid co-channel interference due to channel mobility, we adopt the sub-rating method for its carried channel. We evaluated our scheme using both Markov analysis and computer simulation. The analytical and simulation results indicate that our scheme may offer better performance than conventional handoff schemes in terms of handoff blocking probability and channel utilization.
