Abstract

The invention discloses a self-adaptive monitor matching anti-interference method of a wireless sensor network. The self-adaptive monitor matching anti-interference method adopts a 'self-adaptive monitor matching window' flexibly adjustable in receiving window size to receive data information transmitted from a source node. A receiving monitor window is maximum in size in an initial state, and a received signal strength indicator measures the strength of wireless signals. When the signal strength is lower than a set threshold value, a cycle rate counter adds 1. When the signal strength is higher than the set threshold value, signal receiving starts. When signal receiving succeeds, a communication window is adjusted to be maximum in size and returns to the initial state. If the receiving fails, the window size is decreased. In the monitoring process, if no interference signal or normal signal is found in M cycles, the size of the receiving monitor window is minimum. When the monitor window is in a minimum state, interference signals always exist in the M cycles, and the window is adjusted to be in an intermediate state. By the adoption of the self-adaptive monitor matching anti-interference method, monitor errors between a transmitting node and a receiving node in a wireless interference environment is effectively decreased, and unnecessary energy consumption and lost data packets are reduced.
