摘要
针对可移动的无线传感器网络提出了基于TCP连接迁移的可靠传输技术,传感器节点加入网络时采用簇节点选择算法确定上层簇节点,当传感器节点移动出所连接簇节点临界区时,采用连接迁移节点选择算法选择迁移的目标簇节点,并进行连接迁移.该技术可以保证传感器节点在移动过程中仍然能够可靠的进行数据传输,具有对传感器节点透明的特点.仿真实验验证了方法的有效性和可行性.
This paper puts forward a reliable transport technology based on TCP connection handoffs for mobile wire- less sensor networks. In this method the cluster node selection algorithm is used by the sensor node to determine the upper cluster node. When the sensor node moves out of the critical region of the cluster node, the cluster node se- lection algorithm for connection handoff is used to locate a new objective cluster node, ensuring the sensor node in the mobile continues to have reliable data transport. The method is transparent to the sensor node. Simulations vali- dated the effectiveness and feasibility of the method.
