Abstract:The research focuses on communication problem in sparse Ad hoc networks where links easily disrupt.This paper presented links precompensation.Firstly gave the definition of critical nodes and the method to detect them,then proposed power control compensation algorithm, through improving nodes’ power to improve the network connectivity and eliminate the impact of the critical node. In the NS2 simulator,designed simulation platform for the scheme.The results show that the links precompensation algorithm can improve network throughput and data delivery ratio.
