Dynamic channel allocation and optimal detection for MAC in CDMA ad hoc networks

A medium-access control (MAC) protocol for spread-spectrum ad hoc networks with dynamic channel allocation (DCA) is presented. DCA can support large systems with smaller spreading gains by dynamically assigning channels only when a node has a packet to transmit. It is shown that DCA is collision free. By assigning channels dynamically, DCA offers improved throughput normalized by available bandwidth.
