Research On Wireless Sensor Networks Adaptive Routing Mechanism With Data Aggregation

With the development of sensor, embedded computing, wireless communication, wireless sensor networks will be paid more and more attention, routing protocols and data aggregation technologies of wireless sensor networks are key to improve overall network performance if which we combine the two effectively. The bandwidth, energy, and throughput of the wireless sensor network are very limited and it often lay in bad environment, so in the routing, we not only collect the network data accurate and send it to sink node timely, but also require network load balancing and improve energy efficiency in the routing process.Wireless sensor network is an applications-related network, so its routing algorithm design must adapt to specific application environmental conditions. This paper use distribute network environment of coal mine structure expand our wireless sensor networks routing research. We research the transmission routing and energy saving combine data aggregation technology with the goal of low power consumption and dynamic transmission, the main work and achievements are as follows:(1)We research wireless sensor network routing protocol from its features, key technologies and its design guidelines, and we analyze routing protocols of wireless sensor networks from planar routing and hierarchical routing, and make clear its advantages and disadvantages.(2)We study the architecture of data aggregation technology in wireless sensor networks. We analyze data aggregation technology from network layer, application layer and layer of separate data aggregation technology, and research its related model.(3)We design routing algorithm of banded wireless sensor network, and proposed a dynamic routing algorithm to adapt banded network environment. In the environment of coal mine, we establish a network routing model for banded network feature using artificial way of deployed nodes. Through the establishment of gradient field and dynamic routing algorithm we design the detailed measure, making the energy consumption to its gradient region and carry out energy balance in routing process.(4)In the base of dynamic routing of banded wireless sensor networks, we propose a data aggregation routing algorithm. We research data aggregation algorithm from data-centric features of the aggregation -driven routing and combined with the measure of data aggregation algorithms. With threshold, priority setting and sleep mechanisms of data aggregation, we optimize the dynamic routing algorithm, to some extent; it can reduce the energy consumption and improve network performance.
