Abstract
The high mobility of nodes in mobile ad hoc networks (MANETs), there exist frequent link breakages which lead to frequent path failures and route discoveries. MANET routing protocols have to deal with link breaks, which occur due to the frequent movement of the nodes and a dynamic network topology. The latency that occurs during this retransmission is referred to as rerouting time. There are several researches have been proposed by different authors to enhance the rerouting time. One such approach is the buffer zone routing, where the transmission area of a node is isolated into a safe zone near to the node, and an unsafe zone close to the end of the transmission range. Be that as it may, this methodology has a couple of limitations and constraints, such as buffer zone size and network load etc. In this we propose a enhance buffer zone transmission, where the nodes within this buffer forms a virtual zones by considering node energy level. However this paper enhance this study by introducing virtual zone into unsafe zone by considering an energy aware reactive routing technique based on existing reactive protocols. The introduction of virtual zone increases the network performance. The proposed mechanism decreases the rerouting time and it recusehop length. The proposed experiment is conducted in NS3 to analyze the performance.
