Path Failure Detection in Wireless Sensor Networks
The IEEE 802.15.4 standard for lower-power low-cost low-data-rate in wireless personal area networks. A tree topology is used to construct a wireless sensor network for data delivery applications. Data delivery failures occurs the form of mobile node movements and topology changes. The mobile node patterns to reduce the frequency router reconstruction and transmission of data to mobile nodes efficient. To increase the data delivery ratio and mitigate the effects of packet loss caused by the mobile nodes.
