Minimizing the Packets Drop by System Fault in Wireless Infrastructure less Network Due to Buffer Overflow and Constrained Energy

Abstract

A mobile ad hoc network is a wireless-infrastructure less network and acts in a peer to peer manner. The communication between communicating entities is possible by multi-hop manner if they are not present in the radio communication range of one another.Routing in MANET facing the problem of packet drop either by malicious activities or by system faults. Major packet drop due to system fault is buffer overflow and constrained energy.The node present in the MANET is equipped with the battery, and during the mission, there is no possibility to recharge or replace it. Routing is the best way to manage the energy of the node and further minimize the packet drop due to constrained energy. MANET is very sensitive to delay regarding communication. The packet drop due to buffer overflow is due to the problem in either queue length at node buffer or packet forward. Thus the early congestion control mechanism is needed in MANET to prevent the packet drop due to buffer overflow. This paper address the issue of packets dropped due to buffer and energy of node in MANET by computing the queue length at node buffer and residual energy of the node during the route computation process. If the queue length and residual energy of the node are more than the predefined threshold value then the node does not participate in the communication. The performance of the proposed work is evaluated by the network simulator in terms of delivery and lifetime.
