Under the traditional “data Mules” scheme in Wireless Sensor Networks, nodes cannot send the data until the Mules move nearby, which leads to longer data delay. To overcome this shortcoming, this paper improve the “data Under the traditional “data Mules” scheme in Wireless Sensor Networks, nodes cannot send the data until the Mules move nearby, which leads to longer data delay. To overcome this shortcoming, this paper improve the “data Mules” through changing the working area of the Mules and designing its track. According to the mathematical analysis, we can find that reducing the working area of the Mules and its overlapped part can significantly reduced data delay and enhance the equity among sensor nodes. On the basis of this conclusion, a novel thinking and several recommendatory schemes are proposed. The simulation result shows that the new algorithms are significantly superior to traditional one in the aspects of data delay and nodes’ equity.

Data Latency

In wireless sensor networks, node placement plays a significant role in terms of meeting design goals, such as cost effectiveness, connectivity, lifetime, and data latency. In tunnel environments, the energy consumption of sensor nodes and relay nodes is imbalanced because of the long and narrow shape of tunnels. In this article, to reduce the use of extra batteries and the number of forwarding times for a message, we propose a new approach to assist in the placement of relay nodes for two-tier wireless sensor networks in a tunnel environment. The approach proposed is based on the principle that working relay nodes can change approximately at the same time during network operation. It seems the relay nodes move to a new place when they are instead by dormant relay nodes. The approach provides a novel method that has been proved to find optimal places to deploy relay nodes in tunnel environment. Moreover, the approach balances the energy consumption of entire sensor nodes and prolongs the lifetime of entire networks significantly, which is shown in simulations.
