In this papers, the authors detail the efficient MAC (Medium Access Control) protocol for heterogeneous cellular network. Present 3G-cellular radio access network cannot support many concurrent high data rate unicast (or) flows due to limited radio resources. They proposed MAC protocol for Heterogeneous Cellular network (HC-MAC). The heterogeneous network uses a proprietary protocol for communication within the network and TCP/IP for connection with other networks. Here they study here how the 802.11 Medium Access Control (MAC) protocol can be applied and how it performs in the Heterogeneous Cellular network (HC-MAC). By exploiting the fact that timeout intervals are not explicitly specified, without modifying the standard, they propose a new timing structure for the Distribution Coordination Function (DCF) and the handshake of Request-To-Send (RTS) and Clear-To-Send (CTS) to handle increased signal propagation delay in Heterogeneous Cellular network (HC-MAC)
