PEGASIS: Power-efficient gathering in sensor information systems
TL;DR: PEGASIS (power-efficient gathering in sensor information systems), a near optimal chain-based protocol that is an improvement over LEACH, is proposed, where each node communicates only with a close neighbor and takes turns transmitting to the base station, thus reducing the amount of energy spent per round.
Proceedings ArticleDOI
Spray and wait: an efficient routing scheme for intermittently connected mobile networks
TL;DR: A new routing scheme, called Spray and Wait, that "sprays" a number of copies into the network, and then "waits" till one of these nodes meets the destination, which outperforms all existing schemes with respect to both average message delivery delay and number of transmissions per message delivered.
Proceedings ArticleDOI
Power-aware routing in mobile ad hoc networks
TL;DR: In this article, the authors present a case for using new power-aware metn.cs for determining routes in wireless ad hoc networks and show that using these new metrics ensures that the mean time to node failure is increased si~cantly.
Journal ArticleDOI
PAMAS—power aware multi-access protocol with signalling for ad hoc networks
TL;DR: A new multiaccess protocol based on the original MACA protocol with the adition of a separate signalling channel that conserves battery power at nodes by intelligently powering off nodes that are not actively transmitting or receiving packets.
Journal ArticleDOI
Data gathering algorithms in sensor networks using energy metrics
TL;DR: This paper presents an improved scheme, called PEGASIS (power-efficient gathering in sensor information systems), which is a near-optimal chain-based protocol that minimizes energy, and presents two new schemes that attempt to balance the energy and delay cost for data gathering from sensor networks.
