Power saving technique for controlled broadcast of query packet in MANETs

In computer communication networks, every routing-protocol makes a route-discovery to find the optimal path which involves broadcasting of the query-packet over the network. It becomes too expensive when query-packets circulate unnecessarily in the network. These undesirable packets cause the problem of congestion in the network. Time-efficient BERS (tBERS) is one of the controlled flooding techniques that lessens such expenses. From our results, we analysed that its performance in terms of query-retransmission and link-breaks degrade as route-reconstruction problem increases. In such situations, we need to lessen the retransmission of query-packets due to link breaks. In this paper, we have proposed energy-efficient BERS (eBERS) technique that reduces the retransmission of the query-packets. It reduced the retransmission between the magnitude of 15%-20% and energy exhaustion ratio between 29%-56% in tBERS. Furthermore, eBERS also reduced the number of link breaks and average latency between 9%-25% and 36%-46%, respectively.
