Protocol Independent Multicast-Sparse Mode (PIM-SM): Protocol Specification
Deborah Estrin,Dino Farinacci,Ahmed Helmy,David G. Thaler,S. Deering,Mark Handley,Van Jacobson,C. Liu,Puneet Sharma,L. Wei +9 more
TL;DR: This document specifies Protocol Independent Multicast - Sparse Mode (PIM-SM), a multicast routing protocol that can use the underlying unicast routing information base or a separate multicast- capable routing Information base.
Proceedings ArticleDOI
IMPORTANT: a framework to systematically analyze the Impact of Mobility on Performance of Routing Protocols for Adhoc Networks
TL;DR: This framework aims to evaluate the impact of different mobility models on the performance of MANET routing protocols, and attempts to decompose the routing protocols into mechanistic "building blocks" to gain a deeper insight into the performance variations across protocols in the face of mobility.
Journal ArticleDOI
Advances in network simulation
Lee Breslau,Deborah Estrin,Kevin Fall,Sally Floyd,John Heidemann,Ahmed Helmy,Polly Huang,Steven McCanne,Kannan Varadhan,Ya Xu,Haobo Yu +10 more
TL;DR: The Virtual Inter Network Testbed (VINT) project as discussed by the authors has enhanced its network simulator and related software to provide several practical innovations that broaden the conditions under which researchers can evaluate network protocols.
Journal ArticleDOI
The IMPORTANT framework for analyzing the Impact of Mobility on Performance Of RouTing protocols for Adhoc NeTworks
TL;DR: This framework aims to evaluate the impact of different mobility models on the performance of MANET routing protocols, and attempts to decompose the reactive routing protocols into mechanistic ‘‘building blocks’’ to gain a deeper insight into the performance variations across protocols in the face of mobility.
Proceedings ArticleDOI
Energy-efficient forwarding strategies for geographic routing in lossy wireless sensor networks
TL;DR: The analysis, simulations and experiments all show that the product of the packet reception rate (PRR) and the distance traversed towards destination is the optimal forwarding metric for the ARQ case, and is a good metric even without ARQ.
