Power level impact of radio signals on the effectiveness of transmission protocol with the usage of the "Hot-Potato" protocol in WSN networks

nr katalogowy: 78832

With the development of wireless network technology, the popularity of the wireless sensor networks is still increasing. These kind of networks consist of multiple, distributed, independent micro-devices that contain a radio system for transmitting and receiving radio signals. The main goal of distributing such devices in certain area is to perform a certain task, such as: temperature measurement, pressure measurement, the degree of air pollution or other parameters or phenomena occurring in the environment. Due to the wide application of wireless sensor networks, the term smart environment is becoming commonly used. Nodes are responsible for downloading the data, pre-processing and transferring them to a neighboring node, and then to the acquisition node, in which the data is collected and further processed and analyzed [11]. Wireless sensor networks are also used in energetics, particularly in communication systems dedicated to the intelligent Smart Grid [4,9], especially in the areas of NAN (Near-Me Area Network) network and and HAN (Home Area Network). WSN nodes can be mounted in a variety of devices of the power grids, mainly in electricity consumption meters [1,2,8]. A major problem is the appropriate design of the network in terms of speed and reliability of its operation. The authors, on example of a virtual WSN network have analyzed the impact of changes in the power level of signals emitted by radio transmitters on the effectiveness of the transfer of data between the nodes, assuming the usage of “Hot Potato" protocol. Increase of the transmit power increases the total transmission range but reduce the number of connections used for the transmission of information between nodes, wherein it is assumed that they will be characterized by worst reliability parameters. The “Hot Potato" protocol is being studied because of its small computing resources demands [6,7], which allows its use as an additional routi[...]
