Sleuthing and Resolving Sensor Node Failure in WSNs.

Abstract

WSN is one of elevated technology domain with large number of applications in various disciplines. Sensor nodes are used in diverse applications to collect variety of information. To increase (Quality of Service) QoS huge number of sensor nodes are deployed in WSNs. The QoS get condensed because of increase in the failure of a sensor node due to battery failure, ecological effects, hardware and software malfunctions. These sensor nodes have to identified and recovered to maintain the good quality of service (QoS). In this paper, the concept of RTD is implemented which is used to calculate the round trip time (RTT). A novel approach is introduced for determining specific discrete RTP which will improve effectiveness by enabling parallel analysis of such RTPs. To maintain the better QoS under failure conditions, identifying and removing such fault sensor nodes are necessary. Hence QoS will be maintained by using energy model technique with the help of Network Simulator (NS2) tool
