提出跨层设计与无信标转发相结合的双信道无信标地理路由协议DBGR.物理层利用功率控制降低网络竞争强度和相关节点的能量消耗;MAC层使用双信道通信模式将控制报文和数据报文隔离并行传输,并通过预约唤醒避免数据信道的过早唤醒问题.实验结果表明,双信道并行传输、功率控制与无信标转发相结合的地理路由设计,可以有效缓解网络冲突,提高协议的能量效率和传输性能.
Proposed a two-channel beacon-free geographical routing protocol DBGR which is a combination of cross-layer design and no-beacon forwarding. The physical layer uses power control to reduce the network competition intensity and the energy consumption of related nodes. The MAC layer uses the dual-channel communication mode to control packets and Data packets are isolated and transmitted in parallel, and premature awakening of data channels is avoided by reservation wakeup.Experimental results show that the combination of dual-channel parallel transmission, power control and non-beacon forwarding can effectively mitigate network conflicts and improve Protocol energy efficiency and transmission performance.
