An Efficient Secure Data Transmission for Adaptive Hello Messaging Scheme in Manet

R.Gokila, S.Manikandan

In mobile ad-hoc networks, a hello protocol is generally used to maintain neighbor relationship between the nodes. According to this, each node broadcasts hello packets at regular intervals to discover its intermediate nodes to forward a packet. When the node moves into an inactive region, the transmission of hello packets to those nodes get wasted which results in energy loss. In this paper, We implement a dynamic hello protocol to suppress those inessential hello packets without affecting the link failure detection. Our simulation results implies that the proposed design decreases the energy consumption and delay without any major difference in throughput.
