| 摘 要： | 针对无线传感器网络中节点密集的情况，提出了一个功率可调节的跨层网络策略.节点使用不同的发射功率，且使节点有事先规定数量的邻居节点，其中邻居节点数即为节点度.这样，既保证了网络的连通性，又能有效地降低节点间的竞争冲突.将网络中的节点按照层次划分，选择最小传输功率的上层节点作为父亲节点来构造路由树，计算出节点的候选父亲节点集，在父亲节点失效的情况下，选择候选集中的节点传输来解决.实验结果表明，通过这样的策略，可以提高网络的吞吐量，提高数据传输的速率.

| Abstract: | A cross layer network strategy with power regulation is proposed for the wireless sensor networks with dense nodes. Under this strategy, nodes use different transmission power for data transmission and so that each node has a predetermined number of its neighbor nodes, or node degree. It thus guarantees the network connectivity, and can effectively reduce the competition conflict between nodes. The nodes in the network are divided according to the hierarchy. The upper node with the minimum transmission power is selected as the father node to construct the routing tree, and the candidate father node sets for the nodes are calculated. In the case of the failure of the father node, candidate father nodes are selected for transmission to solve the problem. The experimental results show that this strategy can improve the network throughput and the rate of data transmission. |
