WSNs中基于转发区域调整的能效地理路由

Forwarding area-tune energy efficient geographic routing in Wireless Sensor Networks

摘要:

针对无线传感网络(WSNs)的数据传输问题，提出基于转发区域调整的能效地理位置路由(FAEG)。FAEG限定了数据包的转发区域，构建候选转发节点集，并从节点集中选择权重大的节点传递数据包；通过节点剩余能量和离目的节点距离信息计算节点权重，使剩余能量大和离目的节点近的节点具有优先传递数据包的资格，提高了路由稳定性。节点遭遇路由空洞时，则调整转发区域，在更广范围内选择传输数据包的节点。仿真结果表明，提出的FAEG降低了能耗，并提高了数据包传递率。

Abstract:

Forwarding Area-Tune Energy Efficient Geographic(FAEG) routing is proposed to solve the problem of data transmission in Wireless Sensor Networks(WSNs). In FAEG, the forwarding region of packet is controlled, and forwarding node set is constructed. The node with big weight is selected to transfer packet. By calculating the weight based on both the remaining energy of the node and the distance from the destination node, the remaining energy of the node is large and the node close to the destination node is qualified to firstly deliver the packet, which improves the routing stability. When a node encounters a routing void, the forwarding area is adjusted to select the node transmitting the packet in a wider area. Simulation results show that the proposed FAEG routing reduces energy consumption and improves packet transmission rate.
