Abstract
A self-adaptive power control opportunistic routing APExOR based on EIETX is proposed to prolong lifetime of wireless sensor networks(WSNs).Considering of nodes’residual energy
improves IETX
and the selecting strategy for forwarding candidates set based on EIETX is proposed.Forwarding energy efficiency model is established through analyzing link quality between nodes
an algorithm with self-adaptive between forwarding candidate set and transmission power is put forward.APExOR protocol based on the above strategy and algorithm is designed.Simulation results show that
compared with power fixed ExOR protocol
APExOR protocol improves throughput and decreases energy consumption of network.
