Wireless sensor networks lifetime assessment model development

Abstract

<p class="R-AbstractKeywords"><span lang="EN-US">In the recent years low power computing systems have gained popularity. Networks, which use low power computer systems and transmitted data by using wireless connection are called wireless sensor networks, which main task is to get the information from sensors and transmission network. Nowadays, the most topical researches pertaining to wireless sensor networks are grounded on the new optimization of structure of network transmission protocol, the routing optimization in transmission network, optimization of network structure, as a result of which the life circle of wireless network sensors is possible to increase. In the present article the methodology for determining the life circle of network is discussed. The approaches in detection of life circle pertaining to the important network nodes are described.</span></p>

Coordinator Role Mobility Method for Increasing the Life Expectancy of Wireless Sensor Networks

“…Using the descriptions of the calculation method for the life expectancy of the wireless sensor network nodes indicated in other articles [3], the condition that is related to the amount of energy remaining in the nodes has been proposed to be integrated on the routing protocol level.…”

“…In previous publication [3], it was stated that wireless sensor networks could be represented with the help of a directed graph. Based on the structure of the graph, each route (v,u) can be used for transmitting information from node v to node u.…”

“…Using the mathematical model of the network that has been defined in article [3] written by the other author, it is necessary to introduce an approach that will list and take into account the remaining amount of power in each of the network nodes. It is certain that the remaining amount of energy in the node is a positive figure.…”
