Effective failure nodes detection using matrix calculus algorithm in wireless sensor networks

Wireless sensor networks are the wireless autonomous networks with a large number of distributed sensor nodes. The quality of service in such WSNs is mainly affected by the failure of sensor nodes. In the existing method, failure sensor nodes are detected by measuring the round trip delay (RTD) time of discrete round trip paths and comparing them with threshold value. A new matrix calculus (MCS) method is proposed using which row and column wise round trip paths will be generated. With the newly generated RTPs it is possible to detect multiple failure nodes by comparing row wise RTPs delay and column wise RTPs delay.
