There are two states in event-driven wireless sensor network, one is non-event state, and the other is event state. In non-event state, the network traffic is very small and the requirement for real-time performance of network is not strict. However, in event state the traffic is large, the critical information would be lost once the link quality goes bad without responding timely. This paper does...
Common channel framework (CCF), a multi-channel mechanism proposed in 802.11 s, extends traditional DCF mechanism and is fully compatible with traditional 802.11 WLAN. According to the characteristics of CCF reaching maximum throughput in the state of no assigning common channel to transmit data, a method to improve the performance of CCF is proposed. In one collide field, under the condition of fixed...
