Analyzing Link Connectivity to Ensure Faster Failure Detection for QoS Routing in MANETs: A Peculiar Outline

The advent and phenomenal success of the mobile ad hoc network (MANET) can be attributed to its flexibility in providing decentralized infrastructure, and better scalability to the network. The fundamental design philosophy behind the infrastructure-less ad hoc network is its capability of self-configuring by wirelessly connecting different mobile devices that are free to move in any direction under topology change in the network. Dynamic link connectivity is an important QoS requirement to maintain network connectivity in a highly dynamic and autonomous topology in MANETs. Furthermore, network must provide proactive solutions for faster failure detection, handling the critical links, and better battery lifetime. Unfortunately, due to highly dynamic topology of MANETs, maintaining link connectivity is an extremely difficult task. Nevertheless, there are still great issues and challenges related to the existing techniques for providing better link connectivity in the network due to its failure in providing efficient robustness in responding to topology change. This paper aims to address the faster failure detection scheme for improving connectivity property of the network, thus, justifying the QoS argument in MANETs. Accordingly, it becomes imperative to address bottlenecks in link re-connectivity for achieving improved link connectivity in order to maximize QoS routing performance of the network by employing faster failure detection.
