Efficient Micro-Mobility using Intra-domain Multicast-based Mechanisms (M&M)
Ahmed Helmy, Muhammad Jaseemuddin, Ganesha Bhaskara
One of the most important metrics in the design of IP mobility protocols is the handover performance. The current Mobile IP (MIP) standard has been shown to exhibit poor handover p…
Contact-Based Architecture for Resource Discovery (CARD) in Large Scale MANets
Saurabh Garg, Priyatham Pamu, Nitin Nahata +1
In this paper we propose a novel architecture, CARD, for resource discovery in large scale Mobile Ad hoc Networks (MANets) which, may scale up to thousands of nodes and may span wi…
The STRESS Method for Boundary-point Performance Analysis of End-to-end Multicast Timer-Suppression Mechanisms
Ahmed Helmy, Sandeep Gupta, Deborah Estrin
Evaluation of Internet protocols usually uses random scenarios or scenarios based on designers' intuition. Such approach may be useful for average-case analysis but does not cover…
Small Large-Scale Wireless Networks: Mobility-Assisted Resource Discovery
Ahmed Helmy
In this study, the concept of small worlds is investigated in the context of large-scale wireless ad hoc and sensor networks. Wireless networks are spatial graphs that are usually…
Fair Stateless Aggregate Traffic Marking using Active Queue Management Techniques
Abhimanyu Das, Deboyjoti Dutta, Ahmed Helmy
In heterogeneous networks such as today's Internet, the differentiated services architecture promises to provide QoS guarantees through scalable service differentiation. Traffic ma…
