A Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without using any centralized access point, infrastructure, or centralized administration. A typical ad hoc network consists of nodes that are usually battery operated devices such as laptops, PDAs, etc., that come together and spontaneously form a network. Hence energy conservation is a critical issue in case of MANETs. The lifetime of a MANET depends on lifetime of its mobile nodes. Research is being carried out to conserve energy of mobile nodes at various levels, i.e., at the hardware level, operating system level and application level. Lot of work has been done to improve the energy efficiency of existing routing protocols for MANETs. There is little work done that address the lifetime issue of MANETs. In this paper, we propose a new protocol that conserves energy of mobile nodes and, hence, enhances the lifetime of the MANET. It is an on-demand routing protocol based on load balancing that uses adaptive threshold energy. The experimental results are compared with that of the popular on-demand routing protocols namely, DSR and AODV.
