Proceedings ArticleDOI
Experimental evaluation of a wireless ad hoc network
S. Desilva,Samir R. Das +1 more
TL;DR: AODV (ad hoc on-demand distance vector) has been implemented as a part of the operating system protocol stack and the performance evaluation reveals that the performance is poor beyond two hops at moderate to high loads.
Journal ArticleDOI
Addressing deafness and hidden terminal problem in directional antenna based wireless multi-hop networks
Anand Subramanian,Samir R. Das +1 more
TL;DR: Simulation results indicate that the protocol can effectively address deafness and directional hidden terminal problem and increase network performance and is evaluated using detailed simulation studies.
Proceedings Article
An Adaptive Memory Management Protocol for Time Warp Simulation.
Samir R. Das,Richard M. Fujimoto +1 more
TL;DR: It is demonstrated that an implementation of the adaptive mechanism on a Kendall Square Research KSR-1 multiprocessor is effective in automatically maximizing performance while minimizing memory utilization of Time Warp programs, even for dynamically changing simulation models.
Proceedings ArticleDOI
BARNET: Towards Activity Recognition Using Passive Backscattering Tag-to-Tag Network
TL;DR: The vision of BARNET (Backscattering Activity Recognition NEtwork of Tags), a network of passive RF tags that use RF backscatter for tag-to-tag communication, is presented and the BARNET tag architecture shows that an ASIC implementation can run on harvested RF power.
Journal ArticleDOI
Adaptive memory management and optimism control in time warp
Samir R. Das,Richard M. Fujimoto +1 more
TL;DR: An adaptive mechanism is proposed based on the Cancelback memory management protocol for shared-memory multiprocessors that dynamically controls the amount of memory used in the simulation in order to maximize performance and track the time-varying nature of a communication network simulation.
