In this paper, we propose a highly efficient mechanism to improve the reliability of Constant Bit Rate (CBR) Real-Time data packets by deploying Self-Healing nodes within the range of the communicating nodes. The Self-Healing nodes, with its strict vigil over the network have the capability to detect anomalies in data transmission and discrepancies in the communication channel. Added to the Self-Healing nodes is the use of fixed-size buffer in front of every node in the network, which follows FIFO queuing technique improving the reliability by allowing the Real-Time data to reside in it for a pre-defined time defined as PRT (packet resident time). Stipulated retransmission of data packets which are affected by faulty transmission of data ensures reliable transfer which is essential in places like military infrastructure which is devoid of a centralized server. Such applications demand minimum packet loss and hence we resort to AODV protocol. Thus the implementation of our proposal will result in improvement of reliability with a minor compromise on the delay factor.
