摘要:
针对自组织网络的功率控制机制, 提出了一种适用于自组织网络的分布式动态功率控制机制. 源节点首先向目的节点申请保护时隙作为专用数据通信时隙, 申请成功后源节点根据接收到的响应报文的发送功率和接收信号强度指示器, 计算出源节点到目的节点的最优发送功率, 减少发送功率从而节省节点能耗. 基于CC2430无线模块开发了实验验证平台对该机制进行验证, 调整节点的发射功率可以延长节点的生命周期, 减少通信冲突碰撞, 而基于信标帧调度的网络提升了网络的容量. 实验结果表明, 该动态功率控制机制能有效降低网络能耗,同时网络整体容量也得到了一定的改善.
Abstract:
A distributed dynamic power control mechanism is presented for Ad Hoc networks. Source node applies for guaranteed time slot as a special data communication time slot, after the application is successful, source node calculates the optimal transmission power to destination node according to the received response packet transmission power and received signal strength indicator. Reduction of transmission power can save node energy consumption. Based on the CC2430 wireless module, experimental platform to verify this mechanism is developed. Adjusting the transmission power of nodes can prolong the life cycle and reduce conflict. Based on the principle of beacon frame scheduling, the network capacity can be increased. The experimental results show that this dynamic power control mechanism reduces the node energy consumption and improves the network capacity.
