In cellular networks, it is vital to allocate communicationchannels efficiently because the bandwidth allocatedfor cellular communication is limited. When mobile hostsmove from one cell to another cell, to provide uninterruptedservice, the new cell should have enough channels to supportthe ongoing communication of the mobile hosts thatmoved into the cell. If channels are statically allocated,as is the case in current cellular networks, a cell may runout of channels when large number of mobile hosts moveto a cell, thus degrading the quality of service. To overcomethis problem, dynamic channel allocation approacheshave been proposed. Under dynamic channel allocation,channels are allocated to cells on demand, thus increasingchannel utilization and hence improving the quality of service.Such channel allocation approaches fall under twocategories, namely, centralized and distributed. Centralizedapproaches are neither scalable nor reliable, while distributedapproaches have the potential to be both reliableand scalable. In this paper, we present a distributed dynamicchannel allocation scheme for cellular networks thatis fault tolerant. Our approach can tolerate the failure ofmobile nodes as well as static nodes and enhance the qualityof service by making efficient reuse of channels.
