ABSTRACT
In recent years, Internet Of Things become the focus of international discussion
and research, many countries will have it up to the national strategic level. "Internet of
Things" refers to a variety of information sensing device, such as radio frequency
identification devices(RFID), infrared sensors, global positioning systems,
laser scanners and various devices and the Internet combine to form a
huge network. The aim is to have all the items connected with the network, the
system can be automated, real-time identification of objects, locate, track, monitor and
trigger the corresponding event.
This paper studies the wireless sensor network things together in the transmission
routing algorithm clustering algorithm. This material associated with the wireless sensor
network is dynamic, resource-constrained characteristics and application requirements,
expand the efficient routing protocols and algorithms research, the main work papers
and innovative achievements include:
1) In the analysis based on the WCA proposed IWCA (Improved Weighted
Clustering Algorithm) algorithm to improve performance while reducing overhead, and
maintain the general characteristics of the algorithm. Paper first describes the
background of clustering algorithm, and then explain the lack of several clustering
algorithms. Then focuses on the IWCA clustering algorithm, and finally through the
simulation of the clustering algorithm and WCA algorithms for performance
comparison.
2) comparative study of existing sensor network routing protocols, refer to LEACH
clustering algorithm and MTP protocol, proposed a basis for the MTP protocol LEACH
clustering will introduce the idea of coming in improved methods, that the energy
intensity of the network nodes based on stratification, then the distinction between
clusters on each floor, the energy balance of the sensor nodes to improve network
lifetime. Experiments show that the routing algorithm can improve the network lifetime.
