JMT_V1_N3_RP4 Vemana Chary Padmanabham Bhima Prabhakara Rao Journal on Mobile Applications and Technologies 2394-0239 1 3 28 35 MANET (Mobile Adhoc Network), Energy Efficient, Request Sharing, Power Consumption, Geographic Routing Protocols In MANET (Mobile Adhoc Network), power is one of the major issue. MANET devices depend on limited battery power. However, routing in mobile networks is a challenging task and requires specialized routing protocols that are designed to cater to mobile environment factors, such as node connectivity, life time of node mobility, data transmission and Packet Delivery Ratio. This paper proposed a new scheme called Enhance Adaptive Position Update (E-APU) routing protocol which improves the existing on-demand routing protocols by introducing a power efficient scheme in the whole MANET. The main goal of this paper is not only to extend the lifetime of each node, but provides the lifetime of each node connection with low power consumption. The paper presents a qualitative comparative study of geographic position based routing protocols with forwarding strategies for energy consumption and end to end delay. With the growing popularity of positioning devices, geographic routing protocols are one of the choices for use in Mobile Ad hoc Network. Periodic broadcasting of packets that contain the geographic location coordinates of the nodes is a popular method used by most Geographic routing (GEO) protocols to maintain neighbor positions. Ultimate aim is to reduce the energy consumption and receive more packets at minimum end to end delay with adaptive position updates. In addition, this proposed Enhance Adaptive Position Update (E-APU) scheme dynamically gives better solution for node movements. August - October 2014 Copyright © 2014 i-manager publications.
