- Abstract
- This paper describes a method for effectively performing resource allocation competition in a synchronous wireless distributed communication system. In synchronous wireless distributed communication, since there is no control station for managing resources, user equipment (UE) compete to allocate resources. Among the existing competition methods, two methods with good performance are CS-CDAD (carrier sense-collision detection and drop) and SCMAC (Slotted-Contention-Based MAC). CS-CDAD has high system stability, but its performance is somewhat inferior to SCMAC. SCMAC has the best performance among all methods, but lacks stability. In this paper, we propose two new resource allocation competition methods that combine only the advantages of these two methods. One is a modified SCMAC algorithm, and the other is a combination of slotted carrier sense multiple access with collision avoidance (CSMA/CA) and SCMAC. The proposed methods have good system stability and show high performance like SCMAC.
