Description
Summary:Currently deployed wireless emergency networks possess low spectrum efficiency, similar to their civilian wireless counterparts. It's due to the traditional radio frequency partitioning where each service has uniquely assigned bandwidth. To alleviate the problem one can propose dynamic channel assignment as a promising foundation for physical and link layer design of future wireless emergency communication networks. Here we identify functional requirements and system specifications for mobile ad hoc emergency networks built on top of cognitive radio. We also propose a simple Cognitive Radio medium access control protocol applicable to our network model, adopted from distributed channel assignment algorithm of IEEE 802.11
