User mobility in wireless data networks is increasing because of technological advances and the


desire for voice and multimedia applications. These applications, however, require fast handoffs


between base stations to maintain the quality of the connections. In this paper, the authors


describe the use of novel and efficient data structure which dynamically allocates guard channel


for handoffs and introduces the concept of channel borrowing strategy. The proposed scheme


allocates the guard channels for handoff requests dynamically, based on the traffic load for


certain time period. A new originating call in the cell coverage area also uses these guard


channels if they are unused. Our basic idea is to allow Guard channels to be shared between


new calls and handoff calls. This approach maximizes the channel utilization. The simulation


results prove that the channel borrowing scheme improves the overall throughput.
