Abstract


One of the major issues in current routing protocols for mobile ad hoc networks (MANETs)
is the high resources consumed during the route discovery phase of the routing process, such
as wireless bandwidth and battery power. Proper use of location information and
dynamically adjustment of intermediate nodes’ retransmission probabilities adopted by a
number of algorithms contribute to a reduction in the number of retransmissions and
consequently reduce bandwidth and power consumption, but this feat was achieved at a
price on network reachability. However, the amount of power reduction is still short of
meeting users’ satisfaction, services and applications needs. Furthermore, such algorithms
are severely suffered in realistic network environment, due to the presence of noise that
leads to increasing packet-loss. This paper reviewed some current literatures that were
proposed to improve the energy conservation in MANET and highlight the performance
demands required of these protocols to assist researcher in MANET energy conservation as
a good starting point for developing energy conservation algorithm.
