Study on Channel Allocation Strategy Using Time Constraints in Cellular Networks

The new real-time applications like multimedia and real-time services in a wireless network and users will be dramatically increased. However, many real-time services of mobile hosts in a cell cannot be continued because of insufficiency of useful channels. Conventional channel assignment approaches didn´t properly consider the problem to serve real-time applications in a cell. This paper proposes a new realtime channel assignment algorithm based on time constraint analysis of channel requests. The proposed algorithm dynamically borrows available channels from neighboring cells. It also supports a smooth handoff which continuously serves real-time applications of the mobile hosts.
