Congestion Aware Fault Detection Method Using Quality In Service For Improving Data Reliability Rate In Manet

Abstract

Fault tolerance in Mobile Ad-hoc Network is very difficult task. Clustering in Mobile ad hoc network is one of the control scheme used to make MANET global topology less dynamic. The network topology changes normally due to mobility, disconnections, errors of nodes and network partitioning. Fault tolerance is used to improve system consistency. In this paper, an energy efficient fault-tolerant routing algorithm is designed, called the QOS aware Improved Fault Tolerant Routing (QOS-IFTR) Algorithm, which is competent of considerably lowering the packet overhead, while guaranteeing to improve a packet delivery rate. Without a method that tolerates routing fault due to malfunctioning nodes while making routing decision, the performance of mobile ad hoc network protocols will unavoidably be poor, and the routing decisions made by those protocols would be flawed. Proposed QOS-IFTR algorithm improves the energy efficiency while compared to DSR Multipath Routing protocol and AODV routing protocol and reduces the overhead ratio.
