Flooding is the simplest way of broadcasting, in which each node in the network retransmits an incoming message once. Simple flooding technique in wireless Ad-hoc networks causes the broadcast storm problem. However, this technique is inefficient in terms of resource consumption such as bandwidth and energy. This paper presents a new hybrid scheme that combines different techniques that collaborate to reduce overhead and conserve energy. We propose an Energy-Efficient Adaptive Forwarding Scheme, that utilizes the information of the 1-hop neighbouring radios. In this scheme nodes do not need a positioning system or distance calculation to determine their location. In addition to the previous works, the proposed protocol divides the network into different groups based on their transmission-power levels. Therefore, the node which receives HELLO message from different groups is considered a Gateway node. This node efficiently participates in forwarding RREQ packets and the unnecessary redundant retransmission is avoided. The performance evaluation of the proposed protocol shows a reduction in the routing overhead and in energy consumption, when compared with the Pure-Flooding AODV and Dynamic-Power AODV using NS2.
