Journal ArticleDOI
A survey on position-based routing in mobile ad hoc networks
TL;DR: An overview of ad hoc routing protocols that make forwarding decisions based on the geographical position of a packet's destination and previously proposed location services are discussed in addition to position-based packet forwarding strategies.
Journal ArticleDOI
Equation-based congestion control for unicast applications
TL;DR: A mechanism for equation-based congestion control for unicast traffic that refrains from reducing the sending rate in half in response to a single packet drop, and uses both simulations and experiments over the Internet to explore performance.
ReportDOI
TCP Friendly Rate Control (TFRC): Protocol Specification
TL;DR: TFRC is a congestion control mechanism for unicast flows operating in a best- effort Internet environment that has a much lower variation of throughput over time compared with TCP, making it more suitable for applications such as telephony or streaming media where a relatively smooth sending rate is of importance.
Journal ArticleDOI
Network coding: an instant primer
TL;DR: This paper explains what network coding does and how it does it and discusses the implications of theoretical results on network coding for realistic settings and shows how network coding can be used in practice.
Journal ArticleDOI
Contention-based forwarding for mobile ad-hoc networks
TL;DR: A mechanism to perform position-based unicast forwarding without the help of beacons is proposed and results show that CBF significantly reduces the load on the wireless channel required to achieve a specific delivery rate compared to the load a beacon-based greedy forwarding strategy generates.
