Becker, Jing Tian, K. Rothermel posted to mobility sota by eldaly on 2006-08-16 11:42:47 Abstract Copy My Attachments My Copy Abstract Mobility patterns play an important role for performance evaluations of mobile networks. To simulate user movement, existing simulation tools provide only a few simple mobility models (e.g., random movement) suitable for particular scenarios. To evaluate a new scenario, an appropriate model needs to be created, but this requires extra work that distracts the researcher from his/her main task. In general, three key elements determine the mobility of users: the spatial environment, the user trip sequences, and the user movement dynamics (e.g., ...

	Efficient forwarding of symbolically addressed geocast messages Computer Communications and Networks, 2005. ICCCN 2005. Proceedings. 14th International Conference on (2005), pp. 77-83. by F. Durr, C. Becker, K. Rothermel posted to location by eldaly on 2006-08-16 11:26:11 Abstract Copy My Attachments My Copy Abstract Geocast is used to send messages to all hosts located in a geographic area. This target area can be defined either by geometric figures like polygons or by symbolic addresses like city names or room numbers. Geographic routing algorithms, which forward messages based on geographic information, can be used to forward geocast messages. If routing of symbolically addressed messages is based on geometric coordinates, complex mappings between symbolic addresses and their geometric extent as well as complex geometric operations are required. ...
