Preserving energy is a very critical issue in mobile ad-hoc sensor networks (MASNETs) because sensor nodes have a severe
resource constraints due to their lack of processing power and limited in power supply. Since the communication is the most energy
consuming activities in MASNETs, the power use for transmission or reception of packet should be managed as much as possible.
One way to reduce energy consumption is by applying transmission power control (TPC) technique to adjust the transmission power
in communication between nodes. This technique has been widely studied in MASNETs. However, as MASNET applications
emerge, the unique characteristics of this network such as severe resource constraints and frequent topology change suggest that
TPC might be useful to reduce energy consumption in MASNETs. Therefore, we investigate different effects of TPC on Ad
hoc On-Demand Distance Vector (AODV) routing protocols for MASNETs. AODV is used as a medium of communication to
assist the investigation of the effects of TPC in multihop communication in this networks with RandomWay Point (RWP) mobility
model. Our simulation results show a noticeable effects of TPC implementation technique on MASNETs in respect to transmission
energy consumption and packet received ratio at low node mobility. These results support the use of TPC technique to enhance the
performance of multihop AODV routing protocol in MASNETs
