Novel backoff algorithm for WSN based on preferentially transmitting and different traffic levels
一种基于转发优先及流量分级的无线传感器网络退避算法

According to the specialty of WSNs, this paper proposed a new backoff algorithm based on preferentially transmitting and different traffic levels. This scheme defined different traffic levels according to the available messages that nodes could obtain, and adjusted the backoff window; the scheme also gave a priority to the transmitting nodes, which let the current transaction can be preferentially processed. Simulations prove that the proposed algorithm can reduce the collisions effectively, depress the extra energy consumption, achieve a lower latency, and heighten the system throughputs, provides a better performance of WSNs.
