ABSTRACT
This chapter proposes a method to efficiently implement the Medium Access Control Protocol Data Units (MAC-PDU) size optimization in orthogonal frequency-division multiple access modulated two-hop wireless relay networks with infrastructure-based relays. It also proposes a method that reduces the total overhead transmitted in the end-to-end path. The chapter presents the key concept of the proposal and the system model. It analyses the effect of MAC-PDU size on the goodput. The chapter then proposes a method for the optimization of the MAC-PDU size in two-hop wireless relay networks with infrastructure-based relays. It presents the performance of the proposal in terms of end-to-end overhead reduction and goodput gain. The construction of MAC-PDUs in wireless relay networks can be done in two ways. One way to do it is in an end-to-end basis. The other way is to do it in a hop-by-hop basis.
