A research work without considering the power constraint cannot be conceded a fine contribution towards
Mobile Ad Hoc Networks (MANET). As MANET comes into action for some special purpose, but its
fugacity sometimes result degrades in network performance. Although the many prominent features of
MANET like mobility, dynamic change in topology, multi radio relaying, quickly lay down the network
without depending upon fixed infrastructures and many more provides tremendous flexibilities for the end
user but challenges like limited power constraint, reliable data communication, band width utilization ,
network performance and throughput are still needed to be handle very sensibly. As limited battery power
and inefficient routing protocol mechanism are high prone to network partition, in such case the network
needs to be established more than once. Because communication establishment involves many costly
operations like route discovery and route maintenance. The more the network partition the more the packet
drops and packet loss which indeed requires a number of retransmission of packets, consuming network
bandwidth as well as depleting battery power of individual nodes with a higher rate, which are the major
destructive elements in network performance degradation as well as the major cause of reducing individual
node’s life time and network life time. So with all caveat in mind, we have proposed a novel Grid Based
Dynamic Energy Efficient Routing (GBDEER) approach which is aimed to construct an energy efficient
path from source to destination based on grid area, where each grid will have three deferent levels of
transmission power. Every grid will have its own grid supervisor node who will take the responsibility
during data communication, especially when the data is been passed through that specific grid. And
keeping the dynamic nature of MANET in mind, we have also provide the feature of grid subordinate
node, who will take the place of grid supervisor in case the supervisor is moving out of the grid area or
running out of energy from certain threshold level. So we our proposed method not only establishes an
energy efficient path but also concerned a dedicated path which can be used for data communication for a
long period of time without any network partition. Hence this approach will be less prone to all those
problems mentions above by the incorporating an efficient mobility handling mechanism.
