Power Balance AODV Algorithm of WSN in Agriculture Monitoring
Abstract: WSN (wireless sensor
networks) is a kind of energy-constrained network, which has been widely used
in precision agriculture environment monitoring. However, power balance is not
taken into account in traditional routing algorithms. In this paper, a novel
Power Balance Ad hoc On-Demand Distance Vector (PB-AODV) routing algorithm is
proposed on cross-layer design to solve the problem of power balance. The main
idea of our proposed algorithm is that, routing path is established by the
received signal strength indication (RSSI) value in the route discovery process
of PB-AODV. The optimal transmitting power which can be computed by RSSI value,
power threshold and node’s surplus energy is encapsulated into route reply
packet (RRP). Thus, the sender node can adaptively adjust its transmission
power to save energy with the RRP. Simulation results show that the proposed
algorithm is effective for load balancing, and increases the WSN’s lifetime
about 14.3%.
