| Summary: | Saving energy is a very critical issue in wireless
sensor networks (WSNs) because sensor nodes have a severe
resource constraints such as lack of processing power and limited
in power supply. Since the communication is the most energy
consuming activities in WSNs, the power use for transmission or
reception of packet should be managed properly. Transmission
power control (TPC) technique is one of the techniques to reduce
energy consumption which has been widely studied in mobile
ad-hoc networks (MANETs). This technique is implemented by
adjusting the transmission power in communication between
nodes. However, as mobile wireless sensor networks (MWSNs)
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 MWSN. Therefore, we investigate the impact of TPC on Ad
hoc On-Demand Distance Vector (AODV) routing protocol for
MWSNs. AODV is used as a medium of communication to assist
the investigation of the effects of TPC in multihop communication
in MWSNs. The simulation results show that the implementation
of TPC technique has some impact on MWSNs in respect to
transmission energy consumption and transmission power level
required at low node mobility. |
