Path Construction for Data Mule in Target Based Mobile Wireless Sensor Networks

摘要

Evolution in computer networks, Wireless Sensor Network (WSN) has played a significant role in sensing, processing and transmission of data from remote location across the network. There are many target points or point of interests (POIs) in a network that need to be monitored periodically or all the time. These POIs are covered by many static sensor nodes and collectively these sensor nodes form clusters. Each of the cluster contains a cluster head (CH) or relay node which collects the data sensed by the static sensors. One of the cluster has higher priority among the other clusters. So, a path is to be constructed for a data mule to collect data from these relay nodes. This path need to be optimized such that the higher priority relay node will be traversed times equal to its weight in one complete cycle. In this paper, Weighted Target Traversing with Stable Visiting Interval (WTT-SVI) algorithm has been proposed that gives the optimized path for a weighted target.
