Cross-Layer Aided Energy-Efficient Routing Design for Ad Hoc Networks
Jing Zuo, Chen Dong, Soon Xin Ng, Lie‐Liang Yang, Lajos Hanzo · IEEE Communications Surveys & Tutorials · 2015
In this treatise, we first review some basic routing protocols conceived for ad hoc networks, followed by some design examples of cross-layer operation aided routing protocols. Specifically, cross-layer operation across the PHYsical layer (PHY), the Data Link layer (DL) and even the NETwork layer (NET) is exemplified for improving the energy efficiency of the entire system. Moreover, the philosophy of Opportunistic Routing (OR) is reviewed for the sake of further reducing the system's energy dissipation with the aid of optimized Power Allocation (PA). The system's end-to-end throughput is also considered in the context of a design example.
