Tech-Talk: Stable Probabilistic  Routing Schemes for High Mobility Ad hoc Networks
Speaker: Mustafa Bani Khalaf, PhD Candidate, School of Computing
Wednesday 5th December, 2pm-3pm, F29


In this talk, we investigate efficient strategies for supporting stable probabilistic route discovery in Mobile Ad hoc Networks (MANETs). MANETs usually use broadcast mechanisms to discover routes between nodes by flooding the network with RREQ packets. Usually, routes of the high mobility nodes have frequent breakages which result in discovering the same routes frequently. Hence, uncontrolled RREQ packets can cause more channel contention and increase packets collision rate. This is well-known as the broadcast storm problem, and different probabilistic solutions have been suggested to mitigate its side effect. Unlike other proposed schemes, In this study we utilize the probabilistic concept to develop new probabilistic routing schemes called Velocity Aware Probabilistic (VAP) route discovery schemes, to solve the frequent link breakages problem and guarantee that all constructed links are stable in MANETs.  Node velocity is anticipated as a key parameter to control the routing function among the nodes. Routing in Vehicular Ad hoc Network (VANET) communications is also handled in this talk. Simulation experiments confirm that our proposed model significantly outperforms existing well known solutions in terms of RREQ packet overhead and link stability.


Bio: Mustafa Bani Khalaf is a PhD candidate at the School of Computing, Edinburgh Napier University. He joined Edinburgh Napier in January 2010. He received his BSc and MSc in computer Science from the Jordan University for Science and Technology in 2007 and 2009. His PhD thesis is on group communications in Mobile ad hoc Networks (MANETs) and Vehicular Ad hoc Networks (VANETs). Mustafa has already reported a number of his findings in international scholarly journals and IEEE conferences proceedings. He is currently at the writing-up stage. He is a member of the Networks Theme at IIDI under the supervision of Dr Ahmed Al-Dubai and Professor Bill Buchanan. Mustafa is a Chartered Engineer and a member of IEEE.
