A Cross-Layer Solution for Multi-hop Wireless Network

Multi-hop wireless network MAC protocols typically sacrifice packet latency to achieve energy efficiency. Such delays may well increase due to routing protocol operation. For this reason it is imperative that we attempt to quantify the end-to-end delay and energy consumption when jointly using MAC and routing protocols. In order to coordinate the subproblems, cross-layer feedback mechanism is established to ensure different layer interactions. The simulations are conducted to validate the efficiency of the proposed policy.
