A Failure Node Detection based on Discrete Selection in WSNs
Aswini Kavarthapu, Narasimha Rao Sirivella · International Journal of Computer Applications · 2014
In now days, wireless sensor networks applications are frequently used in various technologies for reducing the cost of manufacturing portable wireless sensor nodes. It trend to deploy the large number of portable wireless sensors in WSNs to increase the quality of service (QoS). The QoS is mainly affected by the life time and failure of sensor nodes. If the probability of sensor node failure increase with increase in number of sensor nodes. To maintain the better QoS under failure conditions, identifying and removing such fault sensor nodes are compulsory. In the proposed method faulty sensor node is detected by discrete path selection technique by compare the actual RTT with present RTT. This method is simulated in NS2 on WSNs with eight sensor nodes designed using circular topology.
