Routing Protocol of Wireless Sensor Networks Based on Link-tree Topology Structure

  • 摘要: 无线传感器网络存在能量和计算能力等资源受限的情况,所以能量有效的路由协议成为无线传感器研究的重点和热点关键技术之一.针对低功耗自适应集簇分层型协议没有考虑网络的动态变化而无法适用于大规模无线传感器网络,给出一种基于树形链路拓扑结构的无线传感器网络能量有效路由协议.该协议在簇头节点之间根据剩余存储能量和地理位置信息以及邻近簇首负载程度寻找父节点,通过多次迭代与基站建立树形链路,实现每个簇头节点与基站之间的多跳路由传输.仿真性能分析结果表明:与低功耗自适应集簇分层型协议相比,所给协议可以有效均衡网络能量消耗和整体网络寿命周期.

     

    Abstract: Due to the limitation resources of energy and calculate ability in wireless sensor networks, the energy efficiency routing protocol become one of the most important and hot technologies. Without considering the dynamic of the networks, the typical protocol of low energy adaptive clustering hierarchy could not be applied to the large scale networks. And so an energy efficiency routing protocol based on link-tree topology structure is proposed. According to the residual energy reserves, geographical location and the traffic load of nearby cluster heads, the father node is looked for among the cluster heads. And then after several iterative, the tree link is built to achieve the multi-hops data transmit between the cluster heads and the base station. Comparing with low energy adaptive clustering hierarchy protocol, the results of simulation and performance analysis show that this protocol could significantly balance energy consumption and prolong lifetime for the network.
