A broadband circularly polarized patch antenna is proposed for WLAN system application. Seven identical curved branches extended from the circular patch are designed to generate circular polarization. Simultaneously, seven identical slots are symmetrically etched on the junction of each curved branch and the circular patch. The dimension of the antenna is reduced by 17.8% compared with no slots. The...
Due to the characteristics of the DCF model in 802.11 and P2P users' requirements of both downloading and uploading, P2P traffic frequently causes congestion in WLAN. However, traditional P2P cache cannot alleviates the congestion caused by P2P traffic in WLAN effectively. In this paper, we propose a novel solution called bidirectional cache for this problem. A bidirectional cache which contains a...
Handoff is an indispensable operation in wireless networks to guarantee continuous, effective, and resilient services during a mobile station (MS) mobility. Handoff counting, handoff rate, and handoff probability are important metrics to characterize the handoff performance. Handoff counting defines the number of handoff operations during an active call connection. Handoff rate specifies the expected...
