Mobile wireless sensor network (MWSN) is a wireless ad hoc network that consists
of avery large number of tiny sensor nodes communicating with each other in which
sensornodes are either equipped with motors for active mobility or attached to mobile
objectsfor passive mobility. A real-time routing protocol for MWSN is an exciting area of
research
because messages in the network are delivered according to their end-to-end
deadlines
(packet lifetime) while sensor nodes are mobile. This paper proposes an enhanced
realtime
with load distribution (ERTLD) routing protocol for MWSN which is based on our
previousrouting protocol RTLD. ERTLD utilized corona mechanism and optimal
forwardingmetrics to forward the data packet in MWSN. It computes the optimal
forwarding nodebased on RSSI, remaining battery level of sensor nodes and packet
delayover one-hop. ERTLDensures high packet delivery ratio and experiences minimum
end-to-end delay in WSNand MWSN compared to baseline routing protocol. . In this paper
we consider a highly dynamic wireless sensor network system in which the sensor nodes
and the base station(sink) are mobile.ERTLD has been studied and verified and compared
with baseline routing protocols RTLD,MM-SPEED , RTLCthrough Network Simulator-
