Abstract: | Cognitive Radio (CR) is an intelligent wireless communication technique in order to increase the spectrum efficiency and fairness issues. Cognitive radio has been considered as an efficient means to opportunistic spectrum sharing between primary users (licensed users) and cognitive users. Cross layer design provides cooperation between multiple layers to combine the resources. Multiple Input Multiple Output (MIMO) is a potential solution to minimize the Co channel interference where cognitive radio operating in coexisting environment. Due to unique physical layer characteristics associated with MIMO, network performance is tightly coupled with mechanisms at physical, link, and routing layers. So far, research on MIMO-based wireless ad hoc networks is still in its infancy and few results are available. So resource allocation at each node and multi hop/multipath routing in a MIMO-based wireless Ad Hoc network is needed. This paper describes the novel approach of robust cross layer design for cognitive MIMO ad hoc network for optimal resource allocation. |
