This paper proposes a novel power and location aware medium access control (MAC) protocol, called LAMP (Location Aware MAC Protocol). LAMP is designed for location aware mobile ad-hoc networks (MANETs). LAMP uses the concept of cellular geographical division of the network in order to build a distributed time division multiple access (TDMA) based schedule for transmission, reception and sleep. It allows hosts to avoid overhearing the network and instead sleep and conserve power. Power saving is a significant concern in MANETs as most mobile hosts operate with a limited amount of power available to them. LAMP trades an increase in latency for a reduction in energy consumption, whilst maintaining fairness in the network. The proposed MAC protocol allows hosts to reduce energy consumption by powering their radio transceivers off whilst still maintaining a responsive and fair network. As in cellular networks this approach uses location information to partition the network into hexagonal cells. Once a host knows which cell it is in and can synchronize its clock, it can build a TDMA based transmission and reception schedule. This is a novel advancement over empirically tuned low duty cycle power conservation, as it not only intelligently minimizes power consumption but also avoids interference.

A mobile ad-hoc network (MANET) is a collection of self configuring mobile devices, capable of moving randomly and connected through wireless physical medium without having any fixed infrastructure. All the nodes in a MANET act both as a router and as a host. However, in today’s scenario the biggest challenge in MANET is to reduce energy consumption and overhead of each node, and to give a better packet delivery ratio. This paper gives the new energy based AODV (EBAODV) protocol that will not only reduce the energy consumption but also takes node’s remaining energy. Based on this it will forward the packets in MANET. Simulation results (using Network Simulator NS-2.34) show that significant performance enhancements of energy based AODV (EBAODV) protocol over the original AODV and DSDV protocols in terms of energy consumption and network overhead. Proposed EBAODV gives the acceptable level of packet delivery ratio.
