7  Cross-layer design for device-to-device communication

image

Traditional communication systems were built using a layered structure to provide well-defined but limited interfaces among protocols in adjacent layers. The modular design of the layered structure, where the details of each protocol are hidden, promotes the interoperatability of the communication protocols. Although the protocol details (e.g., states and internal functions) are encapsulated in each layer, this structure prevents the protocols sharing, accessing, and controlling the operations of other protocols, which might be required for efficient data transmission. Therefore, the concept ...
