In this paper, we address two important problems of mobile ad hoc network (MANET)- route failure and congestion, which reduce the data delivery performance of the network. We propose an efficient and reliable data delivery mechanism that introduces the concept of local packet buffering and multilevel congestion detection and control approaches for improving the reliable delivery of data packets. The nodes on an active route buffer incoming packets at their local transport layer queues, and on finding a new path, resume their transmissions. As a result, packet dropping rate of the network decreases. In addition, we employ a multi-level congestion detection and control mechanism at the source and intermediate nodes that can judiciously take the most appropriate decision for congestion control in the network proactively. Various simulations were carried out based on different traffic loads and route failure rates using NS2 simulator to evaluate the performance of the proposed approaches. The results demonstrate that our approaches outperform a number of state-of-the-art approaches in terms of packet delivery ratio and average end-to-end packet delay. © Springer-Verlag 2013.
