PEAS: a robust energy conserving protocol for long-lived sensor networks
TLDR
A robust energy-conserving protocol that can build long-lived, resilient sensor networks using a very large number of small sensors with short battery lifetime, PEAS can extend a sensor network's functioning time in linear proportion to the deployed sensor population. Expand
GRAdient Broadcast: A Robust Data Delivery Protocol for Large Scale Sensor Networks
TLDR
The analysis shows quantitatively the advantage of interleaved mesh over multiple parallel paths and shows that GRAB can successfully deliver over 90% of packets with relatively low energy cost, even under the adverse conditions of 30% node failures compounded with 15% link message losses. Expand
PEAS: a robust energy conserving protocol for long-lived sensor networks
TLDR
This paper presents the design of PEAS, a simple protocol that can build a long-lived sensor network and maintain robust operations using large quantities of economical, short- lived sensor nodes. Expand
A Robust Data Delivery Protocol for Large Scale Sensor Networks
TLDR
GRAB design harnesses the advantage of large scale and relies on the collective efforts of multiple nodes to deliver data, without dependency on any individual ones, and can successfully deliver above 90% of data with relatively low energy cost even under adverse conditions. Expand
A Packet Scheduling Approach to QoS Support in Multihop Wireless Networks
TLDR
A two-tier service model that provides a minimum “fair” allocation of the channel bandwidth for each packet flow and additionally maximizes spatial reuse of bandwidth and an ideal centralized packet scheduling algorithm that realizes the above service model are proposed. Expand
DIRAC: a software-based wireless router system
TLDR
DIRAC, a software-based router system that is designed for wireless networks to facilitate the implementation and evaluation of various channel-adaptive and mobility-aware protocols, provides a flexible framework, which enables advanced network-layer wireless services that are adaptive to channel conditions and host mobility. Expand
Network Performance Centric Security Design in MANET
Security is a basic requirement for mobile ad hoc networks. Several recent papers [4, 1, 2] have started to address security issues in such networks. While these early proposals each have their own… Expand
A software support infrastructure for wireless access routers
TLDR
DIRAC, a software-based router system that is designed for wireless networks to facilitate the implementation and evaluation of various channel-adaptive and mobility-aware protocols, provides a flexible framework, which enables advanced network-layer wireless services that are adaptive to channel conditions and host mobility. Expand
A Robust Data Delivery Proto ol for LargeS ale Sensor
Providing packet-level quality of services in multihop wireless networks
Providing packet-level quality of service (QoS) is critical to support both rate-sensitive and delay-sensitive applications in the bandwidth-constrained, shared-channel, multihop wireless networks.… Expand
