A framework for frameless TDMA using slot chains
Found in: 2012 IEEE 9th International Conference on Mobile Ad-Hoc and Sensor Systems (MASS)
By Gentian Jakllari,Mike Neufeld,Ram Ramanathan
Issue Date:October 2012
pp. 56-64
TDMA MAC protocols suffer from two draw-backs that have reduced its practical appeal, especially for infrastructure-less wireless networks: the need for time synchronization, and the use of Jrames. While there has been extensive research towards achieving ...

Issue Date:May 2014
pp. 209-216
In many deployments of wireless sensor networks (WSNs), the primary goal is to collect and deliver data from many nodes to a data sink. This goal must be met while considering limited resources, such as battery life, in the wireless nodes. In this work, we...

Algorithms for channel assignment in mobile wireless networks using temporal coloring
Found in: Proceedings of the 16th ACM international conference on Modeling, analysis & simulation of wireless and mobile systems (MSWiM '13)
By Amotz Bar-Noy, Ram Ramanathan, Feng Yu, Prithwish Basu
Issue Date:November 2013
pp. 49-58
We model the problem of channel assignment in mobile networks as one of temporal coloring (T-coloring), that is, coloring a time-varying graph. In order to capture the impact of channel re-assignments due to mobility, we model the cost of coloring as C + &...
     
FansyRoute: adaptive fan-out for variably intermittent challenged networks
Found in: Proceedings of the 8th ACM MobiCom workshop on Challenged networks (CHANTS '13)
By Ram Ramanathan, Stephen Dabideen
Issue Date:September 2013
pp. 13-18
We consider the problem of routing in a highly and variably intermittent wireless network to support delay-intolerant as well as delay tolerant applications. Specifically, the links in such a network are too volatile to maintain a consistent topology, rend...
     
Symptotics: a framework for analyzing the scalability of real-world wireless networks
Found in: Proceedings of the 9th ACM symposium on Performance evaluation of wireless ad hoc, sensor, and ubiquitous networks (PE-WASUN '12)
By Abhishek Samanta, Ram Ramanathan, Tom La Porta
Issue Date:October 2012
pp. 31-38
We present a framework for non-asymptotic analysis of real-world wireless networks that captures protocol overhead, congestion bottlenecks, traffic heterogeneity and other real-world concerns. The framework introduces the definition of symptotic1 scalabili...
     
Towards a formalism for routing in challenged networks
Found in: Proceedings of the second workshop on Challenged networks CHANTS (CHANTS '07)
By Prithwish Basu, Rajesh Krishnan, Ram Ramanathan
Issue Date:September 2007
pp. 3-10
Research on challenged or delay/disruption-tolerant networks has exploded in the past few years with a plethora of algorithms targeted at different versions of the problem. Yet, there have been few formal studies on the fundamental nature of the routing pr...
     
Prioritized epidemic routing for opportunistic networks
Found in: Proceedings of the 1st international MobiSys workshop on Mobile opportunistic networking (MobiOpp '07)
By Prithwish Basu, Rajesh Krishnan, Ram Ramanathan, Regina Rosales-Hain, Richard Hansen
Issue Date:June 2007
pp. 62-66
We describe PRioritized EPidemic (PREP) for routing in opportunistic networks. PREP prioritizes bundles based on costs to destination, source, and expiry time. Costs are derived from per-link "average availability" information that is disseminated in an ep...
     
Challenges: a radically new architecture for next generation mobile ad hoc networks
Found in: Proceedings of the 11th annual international conference on Mobile computing and networking (MobiCom '05)
By Ram Ramanathan
Issue Date:August 2005
pp. 132-139
Despite decades of research and development, mobile ad hoc networks (MANETs) continue to lag behind wireline networks in terms of latency, capacity and robustness. We contend that a key reason for this is the way MANETs are thought about and architected to...

Found in: Proceedings of the 4th ACM international workshop on Wireless mobile multimedia (WOWMOM '01)
By Fabrice Tchakountio, Ram Ramanathan
Issue Date:July 2001
pp. 83-94
We consider the problem of routing to endpoints with very high "effective" mobility, i.e., when the period between changes in an endpoint's location is comparable to the time it takes for the location tracking mechanism to converge. This could happen due t...
