Abstract - Mobile Ad hoc Networks (MANET) is an
autonomous collection of multi-hop wireless mobile nodes to
establish communication without centralized infrastructure.
Efficient routing protocol makes MANET reliable. Energy
efficiency is a major problem of mobile Ad-hoc network as
mobile nodes will be powered by batteries with limited
capacity, insufficient source of energy and are difficult to
replace or recharge. In MANET, Energy efficiency is an
important challenge which leads to proposal of an Energy
Efficient Enhanced AODV Routing Protocol that reduces delay,
overhead, increases packet delivery ratio and consumes lesser
energy compared to AODV. In this paper, a review of different
protocols based on Energy Efficient Routing is done
Key Words: MANET, Routing Protocol, AODV, Energy
Efficient Routing.
1. INTRODUCTION
Computers and wireless communication has
undergone a paradigm shift in recent years as a result
mobile computing has evolved as prominent link field
of computer communication. Wireless devices have
evolved in terms of size, form factor and design hence
they can be carried anywhere and can be used at any
time. Due to mobile nature of wireless devices they
have been trimmed down extensively, thus leaving
very little space for battery pack. Biggest constrains of
wireless devices therefore remains finite power supply.
So the need of hour is efficient power management in
wireless communication. Collection of wireless mobile
host forms an ad hoc network which in turn form a
temporary independent of any standalone
infrastructure or centralized information. Fundamental
challenge is constructing a MANET to enable each
device with capability to continuously maintain the
information required to route the traffic. Areas where
primary concern of establishing and infrastructure
based network are time lag and enlarged cost. MANET
solves this primary concern. In continuous efforts of
decreasing form factor and increasing the portability of
mobile devices constraints like battery capacity and
heat dissipation has arise which needs to be tackle
through systematic energy efficiency program.
Technology and research are improvising at steady
but slower pace for enhancing the battery capacity and
minimizing heat dissipation. The solution is energy
efficiency which can be accomplished by doing work
per unit of battery energy consumed and heat
dissipated. Some of the challenges in MANET include
Limited Bandwidth, Limiting power supply, Unicast
routing, Multicast routing, Network overhead, Quality
of service, Energy Efficient, Security, Battery
constraints.
Characteristics of MANET
Communication via wireless network
Easy to Deploy
Dynamic network topology
Nodes perform roles of both hosts and routers
Flexible
No infrastructure needed
Frequent routing updates
Can be set up anywhere
Some of the applications of MANET are
Defence Development
Disaster relief operations
Mine site operations
Urgent business meetings
2. ROUTING PROTOCOL
In this section we study routing protocol which are
of 3 types: Proactive, Reactive, Hybrid
2.1 Proactive Routing Protocol
These type of protocol are also called as Table-driven
protocols. Basically proactive protocol are similar to
connectionless datagram network. Maintains the
routes at all time. Hence proactive protocol have lower
latency. These protocols employs routing strategies
