Abstract: A method and system for determining right of way for a plurality of mobile units at an intersection. The method and system include collecting position and movement information about the plurality of mobile units approaching the intersection; storing a plurality of rules about right of way at the intersection; accessing information about geometry of the intersection; calculating which one or more of the plurality of the mobile units have right of way to enter the intersection, responsive to the position and movement information, the stored rules and the information about geometry of the intersection; and wirelessly transmitting right of way indication signals to one or more of the plurality of the mobile units.

Abstract: A method and device for dynamically changing transmission parameters of broadcast messages transmitted and received by a mobile unit. The method and device include monitoring transmission channel characteristics; dynamically adjusting the transmission parameters of a message based on the monitored transmission channel characteristics; and broadcasting the message using the adjusted transmission parameters. The transmission parameters may include one or more of transmission power, error code rate, and modulation rate. The transmission channel characteristics include one or more of the group consisting of received message density, channel congestion, detected number of message collisions, and signal to interference ratio.

Abstract: A system and method for data transmission on wireless discontinuous channels including a control/safety information (CSI) channel having a duty cycle, and a plurality of service channels. The system and method include: evaluating channel utilization of one or more of the channels; calculating an optimal CSI channel duty cycle responsive to the channel utilizations; adjusting the duty cycle of the CSI channel to the calculated optimal CSI channel duty cycle; broadcasting the optimal CSI channel duty cycle; and transmitting data during the optimal CSI channel duty cycle.

Abstract: A method and system for setting transmission rate of messages transmitted and received by a mobile unit. The method and system include monitoring the speed of the mobile unit; and adjusting the transmission rate based on the speed of the mobile unit. Prevailing conditions may also be determined and the transmission rate may be further adjusted based on the prevailing conditions. The prevailing conditions may be determined based on at least one of states of one or more sensors local to the mobile unit and information provided from an external source over a communication system. The prevailing conditions may include at least one of slick pavement, limited visibility, road construction, object in roadway, accident, dense traffic, and anomalous driving behavior.

Abstract: System and method for facilitating a persistent application session with anonymity between a mobile host and a network host in a wireless communication environment. The system and method include establishing a first communication session between the mobile host and the network host through a first radio access point; receiving a first mobile host identifier and a mobile host address from the mobile host during the first communication session, wherein the first mobile host identifier is different from the mobile host address; terminating the first communication session due to movement of the mobile host; establishing a second communication session between the mobile host and the network host using the first mobile host identifier, through a second radio access point; and receiving a second mobile host identifier from the mobile host during the second communication session, wherein the second mobile host identifier is different from the first mobile host identifier and the mobile host address.

Abstract: A method and system for data transmission on wireless discontinuous channels. The method and system include adjusting ordering of a plurality of transmission units in a queue to be transmitted in a wireless discontinuous channel to reduce unusable channel access time; determining transmission eligibility of each of the transmission units in the queue; and servicing the queue by transmitting the transmission units responsive to the adjusted order.
