Voice over Internet Protocol (VoIP) over a wireless local area network (WLAN) is poised to become an important Internet application. However, unacceptable VoIP performance in the presence of coexisting traffic from other applications is still one of the major problems standing in its development way. For this point, in this paper, a novel adapted adjustment packet segmentation method is proposed to...
TCP's downlink performance during FMIPv6-enabled IEEE802.11g handoff is examined. The use of a user-initiated Handoff Notification, sent prior to handoff, is proposed. Therefore, the correspondent node is aware of the handoff-induced disruption, hence avoiding dropping the congestion window size and triggering Fast Retransmission mechanisms. During handoff, it continues to send data packets which...
Wireless sensor networks have become very useful in so many applications. Applications such as grape monitoring, insect movement monitoring and etc., that allows connectivity between sensor network and Internet can solve many remote control and monitoring problems. IPv6 over low power WPAN (6lowPAN) protocols are suitable technology that can be adapted in wireless sensor network. The deployment of...
During the last years, several wireless Internet service providers (WISPs) install base stations (BSs) to public areas in order to offer Internet feed or voice services to their subscribers. These BSs use the licensed-exempt spectrum, and limited regulations apply during their deployment. Thus, WISPs offering services in overlapping geographical areas need interference-free, access resolution mechanisms...
