Research on routing protocol of Data Collection network based on Wireless Sensor Networks

摘要

A routing protocol of the Data Collection network based on Wireless Sensor Networks (WSN) routing algorithm is put forward in this essay. The Link Estimation and Parent Selection (LEPS) multi-hop routing protocol is mainly researched and the tree topology with a sink node as the root node is presented by using nesC language in the TinyOS operating system. Adopting TOSSIM simulation tools a graphical debugging program Tinyviz is provided for the simulation of this system. Finally, the routing module is replaced by the modified Low Energy Adaptive Clustering Hierarchy (LEACH) protocol. Experimental tests show that the automatic routing function can be realized and the cluster is also determined by the election based on the remaining energy and spatial distribution of the region.
